Can I Be a Full-Stack Developer with Python?

The field of software development is vast, and one question that often arises among aspiring developers is whether they can become full-stack developers using Python. This inquiry is particularly relevant given the increasing popularity of Python as a programming language due to its simplicity, versatility, and extensive library support. In this article, we'll explore what it means to be a full-stack developer, how Python fits into the equation, and the steps you can take to become a proficient full-stack developer using Python.

Understanding Full-Stack Development

Full-stack development refers to the ability to work on both the front-end and back-end of a web application. A full-stack developer is someone who possesses a comprehensive understanding of the various layers involved in web development, allowing them to create complete, functional web applications.

Key Components of Full-Stack Development

Front-End Development: This involves everything that users interact with directly in their web browsers. Front-end technologies typically include:

HTML: The standard markup language for creating web pages.

CSS: Used for styling HTML elements and making web pages visually appealing.

JavaScript: A programming language that enables interactive elements on web pages.

Back-End Development: This encompasses the server side of an application where data is processed, stored, and managed. Key components include:

Server-Side Languages: Languages like Python, Ruby, Java, and PHP are used to create server-side logic.

Databases: Systems like MySQL, PostgreSQL, and MongoDB are used to store and manage application data.

Server Management: Understanding how servers operate and how to deploy applications.

APIs: Application Programming Interfaces (APIs) allow different software applications to communicate. Full-stack developers often build and consume APIs to enable front-end and back-end integration.

Can You Be a Full-Stack Developer with Python?

Yes, you can absolutely become a full-stack developer using Python! In fact, Python is an excellent choice for full-stack development due to its versatility and the wealth of frameworks and libraries available for both front-end and back-end development.

Advantages of Using Python for Full-Stack Development

Ease of Learning: Python’s syntax is straightforward and readable, making it an ideal language for beginners. This can accelerate your learning curve as you delve into both front-end and back-end technologies.

Rich Ecosystem: Python boasts a rich ecosystem of frameworks and libraries that can facilitate rapid development. Some popular choices include:

Django: A high-level web framework that encourages rapid development and clean, pragmatic design. Django comes with built-in features like an ORM (Object-Relational Mapping), user authentication, and admin panel, making it easier to build robust back-end applications.

Flask: A micro-framework for Python that is lightweight and flexible, allowing developers to build web applications quickly and with more control over the components used.

Full-Stack Frameworks: Full-stack frameworks like Django can handle both front-end and back-end development. Django's templating engine allows for easy integration of front-end technologies, while its robust back-end capabilities manage data and business logic.

Community Support: Python has a large, active community, which means you’ll find plenty of resources, tutorials, and forums to assist you in your journey to becoming a full-stack developer.

How to Become a Full-Stack Developer with Python

If you’re looking to become a full-stack developer using Python, here’s a step-by-step approach:

Learn the Basics of Python:

Start with the fundamentals of Python programming. Familiarize yourself with data types, control structures, functions, and object-oriented programming.

Explore Front-End Technologies:

HTML: Learn how to structure web pages using HTML.

CSS: Understand styling and layout techniques to make your web applications visually appealing.

JavaScript: Get comfortable with JavaScript for creating interactive web elements. Frameworks like React, Vue.js, or Angular can also enhance your front-end development skills.

Master a Python Web Framework:

Choose a Python web framework like Django or Flask and learn how to build web applications with it. Focus on understanding how to create routes, handle requests, and manage databases.

Understand Databases:

Learn about databases and how to interact with them. Understand SQL (for relational databases) and NoSQL databases (like MongoDB). Explore ORMs, especially if you're using Django.

Learn About APIs:

Understand how to create and consume APIs. Practice building RESTful services using Django REST framework or Flask.

Deploy Your Applications:

Familiarize yourself with deployment practices. Learn how to use cloud services like Heroku, AWS, or DigitalOcean to host your applications.

Build Projects:

The best way to learn is by doing. Create projects that showcase your skills in both front-end and back-end development. Consider contributing to open-source projects or collaborating with others.

Stay Updated:

The tech field is ever-evolving. Keep learning new technologies and frameworks to stay relevant in the industry. Follow industry news, participate in coding communities, and engage with fellow developers.

Conclusion

In conclusion, becoming a full-stack developer with Python is not only possible but also highly rewarding. With Python’s versatility and the wealth of frameworks available, you can efficiently build both front-end and back-end components of web applications. By following a structured learning path, engaging in practical projects, and continuously improving your skills, you can carve a successful career in full-stack development.

Embrace the journey, stay curious, and enjoy the process of creating dynamic web applications with Python!

WHY SHOULD EVERY STARTUP THINK ABOUT WEB DEVELOPMENT?

Website development is basically the task of creating a website for either the World Wide Web or an internal network (intranet). Development usually involves creating a simple single page of plain text or perhaps with a few lines of code. The next level-up would be building an interactive website, one with interactive elements such as drop-down menus, forms, search boxes, pop-up boxes, and images. Then you get to the really complicated stuff, which involves things like Java, Flash, and other kinds of multimedia systems, as well as database and content management systems.

Every Beginning Shouldn’t be Hard with Professional Website

The importance of websites for startups and small businesses in the world today is undeniable. Online shopping has become extremely popular over the last decade, and this popularity continues to grow. According to numerous web development agencies in Dubai, millions of people turn to the internet to do their shopping, and millions more use alternative shopping websites for the convenience of having everything they need to be shipped directly to their door. Because of these changes in customer expectations, website designers must work closely with marketing professionals to ensure that the final product is both user-friendly, attractive, and appropriate for the target market. This is why website development and marketing are absolutely integral parts of every business’ web strategy.

In fact, many small businesses mistakenly believe that their budgets should only cover the coding and design aspects of their websites. While the coding and design work is essential, be prepared to spend some money on web designers. While not nearly as important as the coding, marketing and advertising elements will make or break your business.

These are some of the things every startup should consider when it comes to web development:

1. It’s Hard to Develop, But It’s Worth Your Time and Money

One of the first things you must understand about website design and programming is that the internet is not a simple system. It’s filled with millions upon millions of programs and scripts, many of which will interact with each other. For instance, when building web pages, you may be writing HTML code, but the program that produces that HTML code is also writing JavaScript code, which interacts with your photos and videos. So, you must hire a professional web development agency in Dubai that’ll provide you with HTML experts. Moreover, these experts should understand the intricacies of all the various programs and scripts that make up your website. Otherwise, you’ll experience a lot of trouble when starting up your website, and it won’t be easy to make it run smoothly.

2. Web Development with Easy-to-Use Platforms

Even though hundreds of different website development platforms are available today, two of the most popular remain WordPress and Joomla. Every web development company in Dubai will tell you that both platforms are prevalent because they’re easy to use and have built-in SEO functionality. As a result, even someone relatively new to website development can build a great website, and it’ll start earning money almost immediately. WordPress, however, has become extremely popular among small businesses because of its flexible licensing terms. While Joomla does have rigid licensing terms, it’s still much more flexible to use than WordPress, and that’s why lots of startups are switching to Joomla over WordPress to develop their websites.

3. You Can Choose a Web Development Platform According to Your iOS

There are several key differences between WordPress and Joomla. Firstly, WordPress uses a version of PHP that’s called PHP/Linux-PHP. While this sounds like almost every website developer’s favorite, it’s actually not. Joomla is written in C++ and therefore works well on both Windows and Linux computers. Thus, if you’re a Windows user, then you can definitely use Joomla.

Secondly, both Joomla and WordPress allow their users to create a “front-end” or user interface, which the end-user sees when visiting a website. In other words, these applications allow the person reading your website to interact with it. If you’re writing code, then you probably know how challenging this can be. You want to be able to interact with the data, the layout, the colors, and so forth from a client, not having to go back to add in the code. If at any point you decide you need professional help, locate the closest web development agency in Dubai and hire them to develop you an incredible website.

4. Having Stable Coding Languages is of Vital Importance

Both WordPress and Joomla are written in very stable languages. Both languages are multithreaded, meaning that multiple threads can execute code simultaneously without any crashing or error messages being displayed. This means that both programmers and developers can simultaneously work on the project without any worries whatsoever. Programmers especially prefer these languages as they’ll never have to worry about them crashing. This, along with the fact that both languages are used worldwide, makes them some of the most sought-after coding languages today.

5. Ease-of-Use Allows Beginners to Develop Incredible Websites

Both Joomla and WordPress platforms are very intuitive, and there are plenty of materials and tutorials available online, so even beginners can develop their first websites. Sometimes hiring a web development company in Dubai may seem completely unnecessary, but truth to be told, it’s always better to leave web development to professionals. Having a professional backup is of vital importance if anything goes wrong with your web development project. For inexperienced people, web development may seem overwhelming. That’s why hiring some of the best web development companies in Dubai is a great idea as they offer various services to startups and small businesses. We at Igloo marketing agency can help you develop a website from your dreams without any hassle whatsoever, so make sure to contact us whenever you need our help.

Wrapping Up

Even though it’s quite straightforward to build your own website from scratch, there’s plenty of things you’d have to learn to complete this project successfully. Besides, building a website isn’t the only thing a startup needs, as marketing is vital for success as well. So, if you don’t want to waste months of your time and energy, make sure to hire professional help and let us do the work for you.

How to Create Your Own AJAX WooCommerce Wishlist Plugin

In this tutorial we will create lightweight wishlist functionality for WooCommerce using AJAX, WordPress REST API, and SVG graphics. WooCommerce doesn’t come with wishlist functionality as standard, so you’ll always need to rely on an extension to do the work for you. Unless you build it yourself for complete control..

Wish Upon a Star

Wishlist functionality will allow users to mark certain products, adding them to a list for future reference. In some eCommerce stores (such as Amazon) multiple wishlists can be created, and these can be shared with others, which makes them ideal for birthdays or weddings. In our case, the WooCommerce wishlist we’re going to create will enable customers to easily revisit products they’re considering.

Our wishlist functionality will add a heart icon to the product thumbs, which when clicked will add the product to a wishlist in a table.

Click the heart icon to add a product to the wishlist

Take a look at the demo for a proper idea of how it works.

1. Create the Plugin Structure

Let’s start by building our plugin. Create a folder with the name “wishlist” and a PHP file with the same name. Add the following snippet to the PHP file:

/* Plugin Name: Woocommerce wishlist Plugin URI: https://www.enovathemes.com Description: Ajax wishlist for WooCommerce Author: Enovathemes Version: 1.0 Author URI: http://enovathemes.com */ if ( ! defined( 'ABSPATH' ) ) { exit; // Exit if accessed directly }

We won’t go into detail about the plugin creation process, but if you are new to plugin development I highly recommend this amazing new course by Rachel McCollin:

WordPress

Introduction to WordPress Plugin Development

Rachel McCollin

Add the Plugin Functions

Let’s sketch out our plan so we know what to build:

Add wishlist toggle to products in loop and single pages using WooCommerce hooks

Create wishlist table shortcode to hold the products added to the wishlist

Create wishlist custom option in the user profile

All the plugin code will go inside the init action for the plugin, as we first need to make sure that the WooCommerce plugin is active. So right after the plugin details add the following code:

add_action('init','plugin_init'); function plugin_init(){ if (class_exists("Woocommerce")) { // Code here } }

And now let’s enqueue our plugin scripts and styles.

Add the following code to the main plugin file:

function wishlist_plugin_scripts_styles(){ wp_enqueue_style( 'wishlist-style', plugins_url('/css/style.css', __FILE__ ), array(), '1.0.0' ); wp_enqueue_script( 'wishlist-main', plugins_url('/js/main.js', __FILE__ ), array('jquery'), '', true); wp_localize_script( 'main', 'opt', array( 'ajaxUrl' => admin_url('admin-ajax.php'), 'ajaxPost' => admin_url('admin-post.php'), 'restUrl' => rest_url('wp/v2/product'), 'shopName' => sanitize_title_with_dashes(sanitize_title_with_dashes(get_bloginfo('name'))), 'inWishlist' => esc_html__("Already in wishlist","text-domain"), 'removeWishlist' => esc_html__("Remove from wishlist","text-domain"), 'buttonText' => esc_html__("Details","text-domain"), 'error' => esc_html__("Something went wrong, could not add to wishlist","text-domain"), 'noWishlist' => esc_html__("No wishlist found","text-domain"), ) ); } add_action( 'wp_enqueue_scripts', 'wishlist_plugin_scripts_styles' );

Here we enqueue the main style.css file and the main.js file for the plugin, also we pass some parameters to the main.js file to work with:

ajaxUrl – required to fetch some data from WordPress, like current User ID

ajaxPost – required to update user wishlist

restUrl – required to list the wishlist items in the wishlist table

shopName – required to add wishlist items to the session storage for non-registered or non-logged-in users

And some strings instead of hardcoding them into the js file, in case they need to be translatable.

So for now create a css, and js folder and put the corresponding files inside those folders: style.css in the css folder and main.js in the js folder.

2. Hook the Wishlist Toggle

Right inside the init action add the following code:

// Add wishlist to product add_action('woocommerce_before_shop_loop_item_title','wishlist_toggle',15); add_action('woocommerce_single_product_summary','wishlist_toggle',25); function wishlist_toggle(){ global $product; echo '<span class="wishlist-title">'.esc_attr__("Add to wishlist","text-domain").'</span><a class="wishlist-toggle" data-product="'.esc_attr($product->get_id()).'" href="#" title="'.esc_attr__("Add to wishlist","text-domain").'">'.file_get_contents(plugins_url( 'images/icon.svg', __FILE__ )).'</a>'; }

Here we add a wishlist toggle to each product in the loop and to each single product layout, using the woocommerce_before_shop_loop_item_title and woocommerce_single_product_summary hooks.

Here I want to point out the data-product attribute that contains the product ID–this is required to power the wishlist functionality. And also take a closer look at the SVG icon–this is required to power the animation. 

3. Add SVG Icons

Now create an images folder in the plugin folder and put the following icon.svg in it:

<svg viewBox="0 0 471.701 471.701"> <path class="heart" d="M433.601,67.001c-24.7-24.7-57.4-38.2-92.3-38.2s-67.7,13.6-92.4,38.3l-12.9,12.9l-13.1-13.1 c-24.7-24.7-57.6-38.4-92.5-38.4c-34.8,0-67.6,13.6-92.2,38.2c-24.7,24.7-38.3,57.5-38.2,92.4c0,34.9,13.7,67.6,38.4,92.3 l187.8,187.8c2.6,2.6,6.1,4,9.5,4c3.4,0,6.9-1.3,9.5-3.9l188.2-187.5c24.7-24.7,38.3-57.5,38.3-92.4 C471.801,124.501,458.301,91.701,433.601,67.001z M414.401,232.701l-178.7,178l-178.3-178.3c-19.6-19.6-30.4-45.6-30.4-73.3 s10.7-53.7,30.3-73.2c19.5-19.5,45.5-30.3,73.1-30.3c27.7,0,53.8,10.8,73.4,30.4l22.6,22.6c5.3,5.3,13.8,5.3,19.1,0l22.4-22.4 c19.6-19.6,45.7-30.4,73.3-30.4c27.6,0,53.6,10.8,73.2,30.3c19.6,19.6,30.3,45.6,30.3,73.3 C444.801,187.101,434.001,213.101,414.401,232.701z"/> <g class="loading"> <path d="M409.6,0c-9.426,0-17.067,7.641-17.067,17.067v62.344C304.667-5.656,164.478-3.386,79.411,84.479 c-40.09,41.409-62.455,96.818-62.344,154.454c0,9.426,7.641,17.067,17.067,17.067S51.2,248.359,51.2,238.933 c0.021-103.682,84.088-187.717,187.771-187.696c52.657,0.01,102.888,22.135,138.442,60.976l-75.605,25.207 c-8.954,2.979-13.799,12.652-10.82,21.606s12.652,13.799,21.606,10.82l102.4-34.133c6.99-2.328,11.697-8.88,11.674-16.247v-102.4 C426.667,7.641,419.026,0,409.6,0z"/> <path d="M443.733,221.867c-9.426,0-17.067,7.641-17.067,17.067c-0.021,103.682-84.088,187.717-187.771,187.696 c-52.657-0.01-102.888-22.135-138.442-60.976l75.605-25.207c8.954-2.979,13.799-12.652,10.82-21.606 c-2.979-8.954-12.652-13.799-21.606-10.82l-102.4,34.133c-6.99,2.328-11.697,8.88-11.674,16.247v102.4 c0,9.426,7.641,17.067,17.067,17.067s17.067-7.641,17.067-17.067v-62.345c87.866,85.067,228.056,82.798,313.122-5.068 c40.09-41.409,62.455-96.818,62.344-154.454C460.8,229.508,453.159,221.867,443.733,221.867z"/> </g> <g class="check"> <path d="M238.933,0C106.974,0,0,106.974,0,238.933s106.974,238.933,238.933,238.933s238.933-106.974,238.933-238.933 C477.726,107.033,370.834,0.141,238.933,0z M238.933,443.733c-113.108,0-204.8-91.692-204.8-204.8s91.692-204.8,204.8-204.8 s204.8,91.692,204.8,204.8C443.611,351.991,351.991,443.611,238.933,443.733z"/> <path d="M370.046,141.534c-6.614-6.388-17.099-6.388-23.712,0v0L187.733,300.134l-56.201-56.201 c-6.548-6.78-17.353-6.967-24.132-0.419c-6.78,6.548-6.967,17.353-0.419,24.132c0.137,0.142,0.277,0.282,0.419,0.419 l68.267,68.267c6.664,6.663,17.468,6.663,24.132,0l170.667-170.667C377.014,158.886,376.826,148.082,370.046,141.534z"/> </g> </svg>

If you are new to working with SVGs I highly recommend you read these amazing tutorials on the subject:

SVG Viewport and viewBox (For Complete Beginners)

Kezz Bracey

Our SVG animation has 3 states:

Default: the heart path

Process: loading group (g tag)

End: check group (g tag)

If you now go to your shop page you will see the unstyled SVG icons piled on top of each other:

Let’s add some styling to fix this mess! Open the style.css file and paste the following code:

.wishlist-toggle { display: block; position: absolute; top: 16px; left: 16px; z-index: 5; width: 24px; height: 24px; outline: none; border:none; } .wishlist-title { display: none; } .entry-summary .wishlist-toggle { position: relative; top: 0; left: 0; display: inline-block; vertical-align: middle; margin-bottom: 8px; } .entry-summary .wishlist-title { display: inline-block; vertical-align: middle; margin-right: 8px; margin-bottom: 8px; } .wishlist-toggle:focus { outline: none; border:none; } .wishlist-toggle svg { fill:#bdbdbd; transition: all 200ms ease-out; } .wishlist-toggle:hover svg, .wishlist-toggle.active svg { fill:#000000; } .wishlist-toggle svg .loading, .wishlist-toggle svg .check { opacity: 0; } .wishlist-toggle.active svg .check { opacity: 1; } .wishlist-toggle.active svg .heart { opacity: 0; } .wishlist-toggle.loading svg .loading, .wishlist-table.loading:before { animation:loading 500ms 0ms infinite normal linear; transform-origin: center; opacity: 1; } .wishlist-toggle.loading svg .heart { opacity:0; } @keyframes loading { from {transform: rotate(0deg);} to {transform: rotate(360deg);} }

The logic here is as follows: 

Initially we show the heart path of our SVG.

When the user clicks on it we will hide the heart path and show the loading path.

Once the loading finishes we will show the checkmark indicating that the product was successfully added to the wishlist.

We will toggle the loading state via JavaScript later; the loading animation is a simple transform rotate. So for now if you refresh the page (don’t forget to clear the browser cache as sometimes old styles are cached) you will see a nice heart icon with each product. 

This toggle currently does nothing, so we’ll sort that out. But for now let’s keep with our plan.

4. Create Wishlist Table Shortcode

Add the following code in the init plugin action:

// Wishlist table shortcode add_shortcode('wishlist', 'wishlist'); function wishlist( $atts, $content = null ) { extract(shortcode_atts(array(), $atts)); return '<table class="wishlist-table loading"> <tr> <th><!-- Left for image --></th> <th>'.esc_html__("Name","text-domain").'</th> <th>'.esc_html__("Price","text-domain").'</th> <th>'.esc_html__("Stock","text-domain").'</th> <th><!-- Left for button --></th> </tr> </table>'; }

This is a very simple shortcode that you can add to any page, and the wishlist items will appear inside it. I won’t describe the shortcode creation process, but if you are new to this, I highly recommend reading this amazing tutorial:

Plugins

Getting Started With WordPress Shortcodes

Rohan Mehta

Make a Wishlist Page

Now from inside the WP admin create a page called “Wishlist” and put the [wishlist] shortcode inside it. Now if you go to the wishlist page you will see an empty table.

Did you notice the loading class on the table? We will remove the loading class with JavaScript later, once the wishlist items are ready to be appended to the table. But for now open the style.css and add the following code:

.wishlist-table { width:100%; position: relative; } .wishlist-table.loading:after { display: block; width: 100%; height: 100%; position: absolute; top: 0; left: 0; content: ""; background: #ffffff; opacity: 0.5; z-index: 5; } .wishlist-table.loading:before { display: block; width: 24px; height: 24px; position: absolute; top: 50%; left: 50%; margin-top:-12px; margin-left:-12px; content: ""; background-image: url('../images/loading.svg'); background-repeat: no-repeat; background-size: 100%; z-index: 6; } .wishlist-table td { position: relative; } .wishlist-table a.details { padding:4px 16px; background: #000000; color: #ffffff; text-align: center; border:none !important } .wishlist-table a.wishlist-remove { display: block; width: 24px; height: 24px; position: absolute; top: 50%; left: 50%; margin-top:-12px; margin-left:-12px; background-image: url('../images/remove.svg'); background-repeat: no-repeat; background-size: 100%; z-index: 6; border:none; opacity:0; } .wishlist-table td:hover > a.wishlist-remove { opacity:1; }

Add the loading.svg image to the images folder:

<svg xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink" viewBox="0 0 471.701 471.701"> <path d="M409.6,0c-9.426,0-17.067,7.641-17.067,17.067v62.344C304.667-5.656,164.478-3.386,79.411,84.479 c-40.09,41.409-62.455,96.818-62.344,154.454c0,9.426,7.641,17.067,17.067,17.067S51.2,248.359,51.2,238.933 c0.021-103.682,84.088-187.717,187.771-187.696c52.657,0.01,102.888,22.135,138.442,60.976l-75.605,25.207 c-8.954,2.979-13.799,12.652-10.82,21.606s12.652,13.799,21.606,10.82l102.4-34.133c6.99-2.328,11.697-8.88,11.674-16.247v-102.4 C426.667,7.641,419.026,0,409.6,0z"/> <path d="M443.733,221.867c-9.426,0-17.067,7.641-17.067,17.067c-0.021,103.682-84.088,187.717-187.771,187.696 c-52.657-0.01-102.888-22.135-138.442-60.976l75.605-25.207c8.954-2.979,13.799-12.652,10.82-21.606 c-2.979-8.954-12.652-13.799-21.606-10.82l-102.4,34.133c-6.99,2.328-11.697,8.88-11.674,16.247v102.4 c0,9.426,7.641,17.067,17.067,17.067s17.067-7.641,17.067-17.067v-62.345c87.866,85.067,228.056,82.798,313.122-5.068 c40.09-41.409,62.455-96.818,62.344-154.454C460.8,229.508,453.159,221.867,443.733,221.867z"/> </svg>

This is the same loading SVG separated from the main icon.svg. We could use SVG sprites, but I decided to stick with a separate loading SVG.

Now, if you go to the wishlist page and refresh it you will see an empty table with loading on it. Nice, let’s move further.

5. Wishlist Custom Option in the User Profile

Our wishlist functionality will work both for logged-in users and guest users. With logged-in users we’ll store the wishlist information in the user’s metadata, and with guest users we’ll store the wishlist in the session storage. 

You can also store the guest users’ wishlist in local storage, the difference being that session storage is destroyed when the user closes the tab or browser, and local storage is destroyed when the browser cache is cleared. It is up to you which option you use for guest users.

Now add the following code to the init action:

// Wishlist option in the user profile add_action( 'show_user_profile', 'wishlist_user_profile_field' ); add_action( 'edit_user_profile', 'wishlist_user_profile_field' ); function wishlist_user_profile_field( $user ) { ?> <table class="form-table wishlist-data"> <tr> <th><?php echo esc_attr__("Wishlist","text-domain"); ?></th> <td> <input type="text" name="wishlist" id="wishlist" value="<?php echo esc_attr( get_the_author_meta( 'wishlist', $user->ID ) ); ?>" class="regular-text" /> </td> </tr> </table> <?php } add_action( 'personal_options_update', 'save_wishlist_user_profile_field' ); add_action( 'edit_user_profile_update', 'save_wishlist_user_profile_field' ); function save_wishlist_user_profile_field( $user_id ) { if ( !current_user_can( 'edit_user', $user_id ) ) { return false; } update_user_meta( $user_id, 'wishlist', $_POST['wishlist'] ); }

Again, in order to remain within the scope of this tutorial, I won’t explain how to work with user metadata. If you are new to this I highly recommend reading this amazing tutorial:

WordPress

How to Work With WordPress User Metadata

Tom McFarlin

All we do here is create a text field input that will hold the wishlist items comma-separated IDs. With show_user_profile and edit_user_profile actions we add the structure of the input field, and with personal_options_update and edit_user_profile_update actions we power the save functionality. 

So once the wishlist is updated it will save to the database. I you go to your profile page you will see a new text field added to it. Add whatever value you want and hit save to test if the update functionality works. With admin CSS you can hide this field if you don’t want users to see it. I will leave it as is.

6. Turn it On!

Now we are ready to power everything up!

Open the main.js file and put the following code in it:

(function($){ "use strict"; })(jQuery);

All our code will go inside this function.

Now let’s gather the required data and create some variables:

var shopName = opt.shopName+'-wishlist', inWishlist = opt.inWishlist, restUrl = opt.restUrl, wishlist = new Array, ls = sessionStorage.getItem(shopName), loggedIn = ($('body').hasClass('logged-in')) ? true : false, userData = '';

As you might remember when we enqueued our main.js script we passed some parameters to it. Here, with JavaScript, we can collect these parameters.

Next, we will create an empty wishlist array that will contains wishlist items. We will need the session storage data with our shop name (the ls variable stands for local storage), and we will need to know if the user is guest or logged-in.

Let me explain the logic here: whenever the user visits the shop page we will need to know if he or she is logged-in or is a guest-user. If the user is logged-in we will need to check if he or she has wishlist items, and if so highlight these items. If not we need to see if there are any items in the session/local storage and highlight those. 

Why this is done like this? Imagine, if the user first visits the website as a guest, adds items to the wishlist, and then decides to login. If the user does not have items registered in the profile wishlist, we will need to show the ones that he or she added before login, that are stored in the session/local storage.

So let’s do that step by step:

If User is Logged-in

Fetch current user data with AJAX

If success update the wishlist

Highlight the wishlist items

Remove the session/local storage

If fail show error message in the console for the developer

if(loggedIn) { // Fetch current user data $.ajax({ type: 'POST', url: opt.ajaxUrl, data: { 'action' : 'fetch_user_data', 'dataType': 'json' }, success:function(data) { userData = JSON.parse(data); if (typeof(userData['wishlist']) != 'undefined' && userData['wishlist'] != null && userData['wishlist'] != "") { var userWishlist = userData['wishlist']; userWishlist = userWishlist.split(','); if (wishlist.length) { wishlist = wishlist.concat(userWishlist); $.ajax({ type: 'POST', url:opt.ajaxPost, data:{ action:'user_wishlist_update', user_id :userData['user_id'], wishlist :wishlist.join(','), } }); } else { wishlist = userWishlist; } wishlist = wishlist.unique(); highlightWishlist(wishlist,inWishlist); sessionStorage.removeItem(shopName); } else { if (typeof(ls) != 'undefined' && ls != null) { ls = ls.split(','); ls = ls.unique(); wishlist = ls; } $.ajax({ type: 'POST', url:opt.ajaxPost, data:{ action:'user_wishlist_update', user_id :userData['user_id'], wishlist :wishlist.join(','), } }) .done(function(response) { highlightWishlist(wishlist,inWishlist); sessionStorage.removeItem(shopName); }); } }, error: function(){ console.log('No user data returned'); } }); }

If User is Guest

Fetch wishlist from the session/local storage

else { if (typeof(ls) != 'undefined' && ls != null) { ls = ls.split(','); ls = ls.unique(); wishlist = ls; } }

As you may have noticed here we have double-AJAX and some helper functions. So first let’s create the actions of the AJAX requests, and after that I will explain our helper functions. I won’t describe in detail the AJAX functionality in WordPress, but if you are new to AJAX and WordPress, I highly recommend reading this amazing tutorial on it:

Plugins

A Primer on Ajax in the WordPress Frontend: Understanding the Process

Tom McFarlin

Our first AJAX request gets the user id and the user wishlist data from WordPress. This is done with a custom AJAX action added to the plugin code file:

// Get current user data function fetch_user_data() { if (is_user_logged_in()){ $current_user = wp_get_current_user(); $current_user_wishlist = get_user_meta( $current_user->ID, 'wishlist',true); echo json_encode(array('user_id' => $current_user->ID,'wishlist' => $current_user_wishlist)); } die(); } add_action( 'wp_ajax_fetch_user_data', 'fetch_user_data' ); add_action( 'wp_ajax_nopriv_fetch_user_data', 'fetch_user_data' );

The most important part here is the action name (fetch_user_data)–make sure it is the same for AJAX and for functions wp_ajax_fetch_user_data and wp_ajax_nopriv_fetch_user_data. Here we’re preparing JSON formatted data with user ID and user wishlist data.

Our next AJAX request updates the user wishlist if there were already wishlist items from session/local storage. Take a close look at the url option–see it is different.

The logic is the same as for the first action–the difference is that here we don’t return or echo any data, but we update the wishlist option for the current user.

function update_wishlist_ajax(){ if (isset($_POST["user_id"]) && !empty($_POST["user_id"])) { $user_id = $_POST["user_id"]; $user_obj = get_user_by('id', $user_id); if (!is_wp_error($user_obj) && is_object($user_obj)) { update_user_meta( $user_id, 'wishlist', $_POST["wishlist"]); } } die(); } add_action('admin_post_nopriv_user_wishlist_update', 'update_wishlist_ajax'); add_action('admin_post_user_wishlist_update', 'update_wishlist_ajax');

And if our user is a guest we will need to check if there are any wishlist details in the session/local storage.

Helper Functions

Before we move to the events part I want to explain our helper functions

Array.prototype.unique = function() { return this.filter(function (value, index, self) { return self.indexOf(value) === index; }); } function isInArray(value, array) {return array.indexOf(value) > -1;} function onWishlistComplete(target, title){ setTimeout(function(){ target .removeClass('loading') .addClass('active') .attr('title',title); },800); } function highlightWishlist(wishlist,title){ $('.wishlist-toggle').each(function(){ var $this = $(this); var currentProduct = $this.data('product'); currentProduct = currentProduct.toString(); if (isInArray(currentProduct,wishlist)) { $this.addClass('active').attr('title',title); } }); }

The first helper function makes the array unique, by removing duplicates, the second one checks if the given value is present in the given array. The next function executes when an item is added to the wishlist and the last one shows items that are in the wishlist.

Add Toggle

Now let’s add a click event to the wishlist toggle to power the actual functionality. On each toggle click event the animation is triggered and if the user is logged-in the wishlist update action fires with AJAX. If the user is a guest the item is added to the session/local storage. 

Now if you go to the shop page, refresh the browser, and click on any wishlist toggle you will see it is working!

$('.wishlist-toggle').each(function(){ var $this = $(this); var currentProduct = $this.data('product'); currentProduct = currentProduct.toString(); if (!loggedIn && isInArray(currentProduct,wishlist)) { $this.addClass('active').attr('title',inWishlist); } $(this).on('click',function(e){ e.preventDefault(); if (!$this.hasClass('active') && !$this.hasClass('loading')) { $this.addClass('loading'); wishlist.push(currentProduct); wishlist = wishlist.unique(); if (loggedIn) { // get user ID if (userData['user_id']) { $.ajax({ type: 'POST', url:opt.ajaxPost, data:{ action:'user_wishlist_update', user_id :userData['user_id'], wishlist :wishlist.join(','), } }) .done(function(response) { onWishlistComplete($this, inWishlist); }) .fail(function(data) { alert(opt.error); }); } } else { sessionStorage.setItem(shopName, wishlist.toString()); onWishlistComplete($this, inWishlist); } } }); });

7. List Items in Wishlist Table

Now it is time to list our wishlist items in the wishlist table we created earlier.

Add the following code into main.js at the very bottom of our wrapper function:

setTimeout(function(){ if (wishlist.length) { restUrl += '?include='+wishlist.join(','); restUrl += '&per_page='+wishlist.length; $.ajax({ dataType: 'json', url:restUrl }) .done(function(response){ $('.wishlist-table').each(function(){ var $this = $(this); $.each(response,function(index,object){ $this.append('<tr data-product="'+object.id+'"><td><a class="wishlist-remove" href="#" title="'+opt.removeWishlist+'"></a>'+object.image+'</td><td>'+object.title["rendered"]+'</td><td>'+object.price+'</td><td>'+object.stock+'</td><td><a class="details" href="'+object.link+'">'+opt.buttonText+'</a></td></tr>'); }); }); }) .fail(function(response){ alert(opt.noWishlist); }) .always(function(response){ $('.wishlist-table').each(function(){ $(this).removeClass('loading'); }); }); } else { $('.wishlist-table').each(function(){ $(this).removeClass('loading'); }); } },1000);

Here we are using the WordPress REST API to get the products by ID in the wishlist array. 

For each of the products we get we are adding a table row with the required data to display. We need the product image, title, stock status, button and price. 

Here we have two options for the REST API: 

using the WordPress REST API 

using the WooCommerce REST API. 

The difference here is that product data is already present in the Woocommerce REST API, but an API key is required. With the default WordPress REST API product data is absent by default, but can be added, and no API key is required. For such a simple task as a wishlist I don’t think that an API key is needed, so we will do it by extending the default WordPress REST API to return our product price, image code and the stock level.

Go to the main plugin file and at the very bottom add the following code:

// Extend REST API function rest_register_fields(){ register_rest_field('product', 'price', array( 'get_callback' => 'rest_price', 'update_callback' => null, 'schema' => null ) ); register_rest_field('product', 'stock', array( 'get_callback' => 'rest_stock', 'update_callback' => null, 'schema' => null ) ); register_rest_field('product', 'image', array( 'get_callback' => 'rest_img', 'update_callback' => null, 'schema' => null ) ); } add_action('rest_api_init','rest_register_fields'); function rest_price($object,$field_name,$request){ global $product; $id = $product->get_id(); if ($id == $object['id']) { return $product->get_price(); } } function rest_stock($object,$field_name,$request){ global $product; $id = $product->get_id(); if ($id == $object['id']) { return $product->get_stock_status(); } } function rest_img($object,$field_name,$request){ global $product; $id = $product->get_id(); if ($id == $object['id']) { return $product->get_image(); } } function maximum_api_filter($query_params) { $query_params['per_page']["maximum"]=100; return $query_params; } add_filter('rest_product_collection_params', 'maximum_api_filter');

All this does is create new fields for REST API and extends the maximum items limit per request. Again, if you are new to this subject I highly recommend reading this series.

For now, if you go to your wishlist table and refresh the page you will see the list of items that are added to your wishlist. 

8. Removing Items From Wishlist

We are almost done; only the remove functionality remains. So let’s create that! Add the following code at the very bottom of the wrapper function in the main.js file

$(document).on('click', '.wishlist-remove', function(){ var $this = $(this); $this.closest('table').addClass('loading'); wishlist = []; $this.closest('table').find('tr').each(function(){ if ($(this).data('product') != $this.closest('tr').data('product')) { wishlist.push($(this).data('product')); if (loggedIn) { // get user ID if (userData['user_id']) { $.ajax({ type: 'POST', url:opt.ajaxPost, data:{ action:'user_wishlist_update', user_id :userData['user_id'], wishlist :wishlist.join(','), } }) .done(function(response) { $this.closest('table').removeClass('loading'); $this.closest('tr').remove(); }) .fail(function(data) { alert(opt.error); }); } } else { sessionStorage.setItem(shopName, wishlist.toString()); setTimeout(function(){ $this.closest('table').removeClass('loading'); $this.closest('tr').remove(); },500); } } }); });

Once the remove icon is clicked (make sure you have a remove.svg in the images folder, you can use whatever icon you want), we need to check if the user is logged-in. If so, we then remove the item ID from the wishlist using AJAX with the user_wishlist_update action. If the user is a guest we need to remove the item ID from the session/local storage.

Now go to your wishlist and refresh the page. Once you click on the remove icon your item will be removed from the wishlist.

Conclusion

That was quite a project! A simple, but comprehensive wishlist feature for your WooCommerce stores. You are free to use this plugin in any project; you can extend, modify it and make suggestions. I hope you liked it. Here is the link to the source files on GitHub. And here is the demo.
