komaedas have you tried straw.page?

(i hope you don't mind if i make a big ollllle webdev post off this!)

i have never tried straw.page but it looks similar to carrd and other WYSIWYG editors (which is unappealing to me, since i know html/css/js and want full control of the code. and can't hide secrets in code comments.....)

my 2 cents as a web designer is if you're looking to learn web design or host long-term web projects, WYSIWYG editors suck doodooass. you don't learn the basics of coding, someone else does it for you! however, if you're just looking to quickly host images, links to your other social medias, write text entries/blogposts, WYSIWYG can be nice.

toyhouse, tumblr, deviantart, a lot of sites implement WYSIWYG for their post editors as well, but then you can run into issues relying on their main site features for things like the search system, user profiles, comments, etc. but it can be nice to just login to your account and host your information in one place, especially on a platform that's geared towards that specific type of information. (toyhouse is a better example of this, since you have a lot of control of how your profile/character pages look, even without a premium account) carrd can be nice if you just want to say "here's where to find me on other sites," for example. but sometimes you want a full website!

---------------------------------------

neocities hosting

currently, i host my website on neocities, but i would say the web2.0sphere has sucked some doodooass right now and i'm fiending for something better than it. it's a static web host, e.g. you can upload text, image, audio, and client-side (mostly javascript and css) files, and html pages. for the past few years, neocities' servers have gotten slower and slower and had total blackouts with no notices about why it's happening... and i'm realizing they host a lot of crypto sites that have crypto miners that eat up a ton of server resources. i don't think they're doing anything to limit bot or crypto mining activity and regular users are taking a hit.

↑ page 1 on neocitie's most viewed sites we find this site. this site has a crypto miner on it, just so i'm not making up claims without proof here. there is also a very populated #crypto tag on neocities (has porn in it tho so be warned...).

---------------------------------------

dynamic/server-side web hosting

$5/mo for neocities premium seems cheap until you realize... The Beautiful World of Server-side Web Hosting!

client-side AKA static web hosting (neocities, geocities) means you can upload images, audio, video, and other files that do not interact with the server where the website is hosted, like html, css, and javascript. the user reading your webpage does not send any information to the server like a username, password, their favourite colour, etc. - any variables handled by scripts like javascript will be forgotten when the page is reloaded, since there's no way to save it to the web server. server-side AKA dynamic web hosting can utilize any script like php, ruby, python, or perl, and has an SQL database to store variables like the aforementioned that would have previously had nowhere to be stored.

there are many places in 2024 you can host a website for free, including: infinityfree (i use this for my test websites :B has tons of subdomains to choose from) [unlimited sites, 5gb/unlimited storage], googiehost [1 site, 1gb/1mb storage], freehostia [5 sites/1 database, 250mb storage], freehosting [1 site, 10gb/unlimited storage]

if you want more features like extra websites, more storage, a dedicated e-mail, PHP configuration, etc, you can look into paying a lil shmoney for web hosting: there's hostinger (this is my promocode so i get. shmoney. if you. um. 🗿🗿🗿) [$2.40-3.99+/mo, 100 sites/300 databases, 100gb storage, 25k visits/mo], a2hosting [$1.75-12.99+/mo, 1 site/5 databases, 10gb/1gb storage], and cloudways [$10-11+/mo, 25gb/1gb]. i'm seeing people say to stay away from godaddy and hostgator. before you purchase a plan, look up coupons, too! (i usually renew my plan ahead of time when hostinger runs good sales/coupons LOL)

here's a big webhost comparison chart from r/HostingHostel circa jan 2024.

---------------------------------------

domain names

most of the free website hosts will give you a subdomain like yoursite.has-a-cool-website-69.org, and usually paid hosts expect you to bring your own domain name. i got my domain on namecheap (enticing registration prices, mid renewal prices), there's also porkbun, cloudflare, namesilo, and amazon route 53. don't use godaddy or squarespace. make sure you double check the promo price vs. the actual renewal price and don't get charged $120/mo when you thought it was $4/mo during a promo, certain TLDs (endings like .com, .org, .cool, etc) cost more and have a base price (.car costs $2,300?!?). look up coupons before you purchase these as well!

namecheap and porkbun offer something called "handshake domains," DO NOT BUY THESE. 🤣🤣🤣 they're usually cheaper and offer more appealing, hyper-specific endings like .iloveu, .8888, .catgirl, .dookie, .gethigh, .♥, .❣, and .✟. I WISH WE COULD HAVE THEM but they're literally unusable. in order to access a page using a handshake domain, you need to download a handshake resolver. every time the user connects to the site, they have to provide proof of work. aside from it being incredibly wasteful, you LITERALLY cannot just type in the URL and go to your own website, you need to download a handshake resolver, meaning everyday internet users cannot access your site.

---------------------------------------

hosting a static site on a dynamic webhost

you can host a static (html/css/js only) website on a dynamic web server without having to learn PHP and SQL! if you're coming from somewhere like neocities, the only thing you need to do is configure your website's properties. your hosting service will probably have tutorials to follow for this, and possibly already did some steps for you. you need to point the nameserver to your domain, install an SSL certificate, and connect to your site using FTP for future uploads. FTP is a faster, alternative way to upload files to your website instead of your webhost's file upload system; programs like WinSCP or FileZilla can upload using FTP for you.

if you wanna learn PHP and SQL and really get into webdev, i wrote a forum post at Mysidia Adoptables here, tho it's sorted geared at the mysidia script library itself (Mysidia Adoptables is a free virtual pet site script, tiny community. go check it out!)

---------------------------------------

file storage & backups

a problem i have run into a lot in my past like, 20 years of internet usage (/OLD) is that a site that is free, has a small community, and maybe sounds too good/cheap to be true, has a higher chance of going under. sometimes this happens to bigger sites like tinypic, photobucket, and imageshack, but for every site like that, there's like a million of baby sites that died with people's files. host your files/websites on a well-known site, or at least back it up and expect it to go under!

i used to host my images on something called "imgjoe" during the tinypic/imageshack era, it lasted about 3 years, and i lost everything hosted on there. more recently, komaedalovemail had its webpages hosted here on tumblr, and tumblr changed its UI so custom pages don't allow javascript, which prevented any new pages from being edited/added. another test site i made a couple years ago on hostinger's site called 000webhost went under/became a part of hostinger's paid-only plans, so i had to look very quickly for a new host or i'd lose my test site.

if you're broke like me, looking into physical file storage can be expensive. anything related to computers has gone through baaaaad inflation due to crypto, which again, I Freaquing Hate, and is killing mother nature. STOP MINING CRYPTO this is gonna be you in 1 year

...um i digress. ANYWAYS, you can archive your websites, which'll save your static assets on The Internet Archive (which could use your lovely donations right now btw), and/or archive.today (also taking donations). having a webhost service with lots of storage and automatic backups can be nice if you're worried about file loss or corruption, or just don't have enough storage on your computer at home!

if you're buying physical storage, be it hard drive, solid state drive, USB stick, whatever... get an actual brand like Western Digital or Seagate and don't fall for those cheap ones on Amazon that claim to have 8,000GB for $40 or you're going to spend 13 days in windows command prompt trying to repair the disk and thenthe power is gong to go out in your shit ass neighvborhood and you have to run it tagain and then Windows 10 tryes to update and itresets the /chkdsk agin while you're awayfrom town nad you're goig to start crytypting and kts just hnot going tot br the same aever agai nikt jus not ggiog to be the saeme

---------------------------------------

further webhosting options

there are other Advanced options when it comes to web hosting. for example, you can physically own and run your own webserver, e.g. with a computer or a raspberry pi. r/selfhosted might be a good place if you're looking into that!

if you know or are learning PHP, SQL, and other server-side languages, you can host a webserver on your computer using something like XAMPP (Apache, MariaDB, PHP, & Perl) with minimal storage space (the latest version takes up a little under 1gb on my computer rn). then, you can test your website without needing an internet connection or worrying about finding a hosting plan that can support your project until you've set everything up!

there's also many PHP frameworks which can be useful for beginners and wizards of the web alike. WordPress is one which you're no doubt familiar with for creating blog posts, and Bluehost is a decent hosting service tailored to WordPress specifically. there's full frameworks like Laravel, CakePHP, and Slim, which will usually handle security, user authentication, web routing, and database interactions that you can build off of. Laravel in particular is noob-friendly imo, and is used by a large populace, and it has many tutorials, example sites built with it, and specific app frameworks.

---------------------------------------

addendum: storing sensitive data

if you decide to host a server-side website, you'll most likely have a login/out functionality (user authentication), and have to store things like usernames, passwords, and e-mails. PLEASE don't launch your website until you're sure your site security is up to snuff!

when trying to check if your data is hackable... It's time to get into the Mind of a Hacker. OWASP has some good cheat sheets that list some of the bigger security concerns and how to mitigate them as a site owner, and you can look up filtered security issues on the Exploit Database.

this is kind of its own topic if you're coding a PHP website from scratch; most frameworks securely store sensitive data for you already. if you're writing your own PHP framework, refer to php.net's security articles and this guide on writing an .htaccess file.

---------------------------------------

but. i be on that phone... :(

ok one thing i see about straw.page that seems nice is that it advertises the ability to make webpages from your phone. WYSIWYG editors in general are more capable of this. i only started looking into this yesterday, but there ARE source code editor apps for mobile devices! if you have a webhosting plan, you can download/upload assets/code from your phone and whatnot and code on the go. i downloaded Runecode for iphone. it might suck ass to keep typing those brackets.... we'll see..... but sometimes you're stuck in the car and you're like damn i wanna code my site GRRRR I WANNA CODE MY SITE!!!

↑ code written in Runecode, then uploaded to Hostinger. Runecode didn't tell me i forgot a semicolon but Hostinger did... i guess you can code from your webhost's file uploader on mobile but i don't trust them since they tend not to autosave or prompt you before closing, and if the wifi dies idk what happens to your code.

---------------------------------------

ANYWAYS! HAPPY WEBSITE BUILDING~! HOPE THIS HELPS~!~!~!

Computer Language

Computer languages, also known as programming languages, are formal languages used to communicate instructions to a computer. These instructions are written in a syntax that computers can understand and execute. There are numerous programming languages, each with its own syntax, semantics, and purpose. Here are some of the main types of programming languages:

1.Low-Level Languages:

Machine Language: This is the lowest level of programming language, consisting of binary code (0s and 1s) that directly corresponds to instructions executed by the computer's hardware. It is specific to the computer's architecture.

Assembly Language: Assembly language uses mnemonic codes to represent machine instructions. It is a human-readable form of machine language and closely tied to the computer's hardware architecture

2.High-Level Languages:

Procedural Languages: Procedural languages, such as C, Pascal, and BASIC, focus on defining sequences of steps or procedures to perform tasks. They use constructs like loops, conditionals, and subroutines.

Object-Oriented Languages: Object-oriented languages, like Java, C++, and Python, organize code around objects, which are instances of classes containing data and methods. They emphasize concepts like encapsulation, inheritance, and polymorphism.

Functional Languages: Functional languages, such as Haskell, Lisp, and Erlang, treat computation as the evaluation of mathematical functions. They emphasize immutable data and higher-order functions.

Scripting Languages: Scripting languages, like JavaScript, PHP, and Ruby, are designed for automating tasks, building web applications, and gluing together different software components. They typically have dynamic typing and are interpreted rather than compiled.

Domain-Specific Languages (DSLs): DSLs are specialized languages tailored to a specific domain or problem space. Examples include SQL for database querying, HTML/CSS for web development, and MATLAB for numerical computation.

3.Other Types:

Markup Languages: Markup languages, such as HTML, XML, and Markdown, are used to annotate text with formatting instructions. They are not programming languages in the traditional sense but are essential for structuring and presenting data.

Query Languages: Query languages, like SQL (Structured Query Language), are used to interact with databases by retrieving, manipulating, and managing data.

Constraint Programming Languages: Constraint programming languages, such as Prolog, focus on specifying constraints and relationships among variables to solve combinatorial optimization problems.

Smart Documentation

I’ve made the decision to tightly integrate documentation into SavageGardens. I hesitated to talk about this aspect of SavageGardens because programmers don’t think of documentation as a language. Still, the goal for SavageGardens is to extend our ability to manage massively complex projects. Documentation is important for large projects, therefore I am including it.

It is a somewhat controversial decision to include documentation as part of the source code. It makes SavageGardens a rather complex application in itself. I am actually asking to integrate a wiki data and discussion forum data inside the source code. It changes the face of SavageGardens but, so be it. I see it as the future. A future which I first saw in StarTrek the Next Generation. That TV Show has several scenes where Geordi La Forge documents his work and accesses documentation. That is the goal. That is the dream.

In SavageGardens, Sub-Layer 0 or the ground level is designated for this purpose. Everything on this layer is strictly for human consumption. Human-to-Human communication. None of its constructs will translate to actual code that the machine will see. Never the less documentation will be tightly integrated into the source code, because part of my design goals is to facilitate in code comprehension and code navigation.

How is documentation related to code comprehension is pretty straight forward. Most of use make use of tutorials before we start using a new library or platform. Why not allow the designer of those libraries to include a tutorial as part of his source code. Let the senior developer include a couple of diagrams as to how the data structures or APIs are structured.

Using documentation for code navigation is new and revolutionary. Most of us navigate code by opening a file manager, going thru the directories, opening and closing source files trying to find a lead or a clue that will help us. Some of us are bit more clever and use grep to do the searching. I find that approach archaic. The future I want to live in is one where you open the source code and you find diagrams that visually outline how the source code is organized. Then you click on parts of these diagrams to navigate different aspects of the source code until you find what you want. Hollywood style.

In the diagram above, its a case use for a team manager. Lets say you are a team manager and you want to audit someone's work. You pull up the smart-diagram of your team. You click on the person you want to audit. It runs a script that pulls up everything he worked on recently. Then you click on what you want to audit. That is code navigation like few of us have seen before.

The following are a set of constructs I am considering. I am borrowing some ideas from the web. I am not importing technologies from the web thou. I see it done all around me and I don’t like it. Apps these days are pretty much integrated web-browsers.

1) Hyper text: The idea to click on text and it brings up source code. Or vice versa. Clicking on a function call and it brings up related documentation. Rather then HTML, I will probably adopt a simpler format like markdown.

2) Smart Diagrams: This idea is the same as image maps in HTML. You have a picture or diagram and certain areas are clickable. This is how you would navigate source code.

3) Mind-Maps: This is to allow developers to brain storm and keep track of themselves and they proceed with their project. Also used to navigate code.

4) Document side scripting: serves a purpose similar to PHP, it allows for dynamic documentation. Documentation that updates itself as changes are made.

NOTE: constructs from lower layers will cooperate in creating self updating documentation. For example every time you create a variable or function, an entry is made in an internal database that keeps track of them. Depending on the changes certain documents will be automatically created and updated. Quick examples of this is a table of contents, an index table and a quick reference guide.

Prevent File Inclusion in Symfony Securely

File inclusion vulnerabilities can be catastrophic if not identified and patched promptly. In Symfony-based web applications, improper handling of file paths can lead to Local File Inclusion (LFI) or Remote File Inclusion (RFI)—giving attackers potential access to sensitive files, system configurations, and even arbitrary code execution.

In this blog post, we’ll cover:

What is file inclusion?

How it affects Symfony apps

Real-world coding examples

How to detect it using our Free Website Security Scanner

A link to our new Web App Penetration Testing Service

Useful references and external links

Also, don’t forget to explore more technical deep dives at our blog: 📌 Pentest Testing Blog

🔍 What is File Inclusion?

File inclusion is a web security issue that occurs when input from users is used to construct file paths. If this input isn't properly sanitized, attackers can manipulate it to include arbitrary files from the local system (LFI) or remote locations (RFI).

Common symptoms of file inclusion:

Unintended file access

Leaked server environment variables

Code execution from included scripts

🧱 Symfony & File Inclusion

Symfony offers a powerful file handling system through its templating engine (Twig), controller logic, and PHP integrations. But this flexibility comes with risk when user input is not carefully validated.

❌ Vulnerable Example (Insecure File Inclusion)

// src/Controller/PageController.php use Symfony\Bundle\FrameworkBundle\Controller\AbstractController; use Symfony\Component\HttpFoundation\Request; use Symfony\Component\HttpFoundation\Response; class PageController extends AbstractController { public function view(Request $request): Response { $page = $request->query->get('page'); $filepath = __DIR__ . '/../Pages/' . $page . '.php'; if (file_exists($filepath)) { include $filepath; } else { return new Response('File not found', 404); } return new Response(); } }

🚨 What’s wrong?

The page parameter is directly passed into the file path.

No input sanitization.

Easy target for ../../../etc/passwd or remote URL inclusion.

✅ Secure File Inclusion in Symfony

Here’s how to fix it using whitelisting and Symfony services:

✅ Secure Version with Whitelisting

// src/Controller/PageController.php class PageController extends AbstractController { public function view(Request $request): Response { $page = $request->query->get('page'); $allowedPages = ['home', 'about', 'contact']; if (!in_array($page, $allowedPages, true)) { return new Response('Invalid page', 400); } $filepath = __DIR__ . '/../Pages/' . $page . '.php'; include $filepath; return new Response(); } }

🔒 More Secure (Using Twig Templates)

Avoid include() altogether and use Twig:

// src/Controller/PageController.php public function view(Request $request): Response { $page = $request->query->get('page'); $allowedPages = ['home', 'about', 'contact']; if (!in_array($page, $allowedPages, true)) { return new Response('Invalid page', 400); } return $this->render("pages/{$page}.html.twig"); }

This approach uses Symfony’s own rendering engine, eliminating direct file access vulnerabilities.

🧪 How to Detect File Inclusion Issues

Use our Free Website Security Checker Tool to instantly assess your website for file inclusion and other critical vulnerabilities.

Future of PHP: What’s Coming in PHP 9? – Discuss upcoming features and trends in PHP development

Introduction

Despite numerous predictions about its decline, PHP continues to be a cornerstone of web development. From powering small personal blogs to massive social media platforms, PHP has proven its resilience and adaptability. With the upcoming release of PHP 9.0, developers are eager to explore the new features and improvements that will shape the future of PHP development Services.

While the official release date of PHP 9.0 remains unknown, community discussions and leaks provide insight into the major changes and enhancements expected. In this post, we will delve into the evolution of PHP, its key features, and why it remains an essential tool for developers worldwide. Additionally, we will discuss upcoming features and trends in PHP development, offering insights into the direction PHP is heading.

Evolution of PHP: A Brief Overview

PHP (Hypertext Preprocessor) has come a long way since its inception in 1994. Originally created as a simple scripting language for building dynamic web pages, PHP has evolved into a robust and powerful language that powers a significant portion of the internet.

PHP 5

Introduced object-oriented programming (OOP) features.

Implemented PDO (PHP Data Objects) for secure database interactions.

Improved exception handling and memory management.

PHP 7

Boosted performance with the Zend Engine 3.0.

Introduced scalar type declarations and return type hints.

Implemented null coalescing operator (??).

Improved error handling with Throwable exceptions.

PHP 8

Brought Just-In-Time (JIT) compilation for significant performance improvements.

Introduced Union Types, Match Expression, Named Arguments, and Attributes.

Implemented Constructor Property Promotion to reduce boilerplate code.

Now, with PHP 9 on the horizon, what can we expect?

Key Features of PHP 8 That Paved the Way for PHP 9

Before diving into PHP 9.0, let's briefly review some of the most impactful features introduced in PHP 8:

1) Just-In-Time (JIT) Compiler

Performance: JIT compilation allows code to be compiled at runtime, significantly improving execution speed for computationally intensive tasks.

Impact: While not drastically enhancing standard web applications, JIT opens doors for PHP’s use in fields like scientific computing and machine learning.

2) Union Types

Flexibility: Allows functions to accept multiple data types, enhancing type safety and robustness.

Example: function foo(int|float $number) { /* ... */ }

3) Attributes (Annotations)

Meta-programming: Introduces structured metadata for classes, methods, and properties.

Usage: Simplifies code annotation, improving integration with frameworks and tools.

4) Match Expression

Simplicity: Provides a more readable alternative to switch statements.

Example:

$result = match ($value) {

    1 => 'one',

    2 => 'two',

    default => 'other',

};

5) Constructor Property Promotion

Efficiency: Reduces boilerplate code for class property initialization.

Example:

class Point {

    public function __construct(private int $x, private int $y) {}

}

6) Nullsafe Operator

Error Handling: Reduces null checks, making code more concise.

Example: $country = $session?->user?->getAddress()?->country;

Anticipated Features in PHP 9

As PHP 9 is still under development, specific features may change. However, based on leaks and discussions, here are the expected improvements:

1) Removal of Deprecated Features

PHP 9.0 will eliminate features deprecated in PHP 8.1 - 8.4, streamlining the language and enhancing maintainability.

2) Transformation of Warnings to Errors

Warnings for undefined variables and properties will be converted into errors, demanding more precise coding practices.

3) Deprecated Dynamic Properties

Dynamic properties, deprecated in PHP 8.2, will now trigger ErrorException, enforcing structured coding practices.

4) New Random Extension

A new random number generator is being introduced, improving performance, security, and simplicity.

5) Standalone Types for null, true, and false

PHP 9.0 will recognize null, true, and false as standalone types, enhancing type precision.

6) Disjunctive Normal Form (DNF) Types

DNF types will enable complex combinations of union and intersection types, making PHP's type system more powerful.

7) Constants in Traits

PHP 9.0 will allow traits to define constants, expanding their capabilities for reusable code blocks.

8) Redact Sensitive Parameters in Backtraces

A crucial security improvement, this feature prevents sensitive data from being exposed in error backtraces.

9) Enhancements in Enum Property Fetching

PHP 9.0 will simplify the retrieval of enum properties in constant expressions, making enums more useful.

10) Additional Changes

Changes to return types in DateTime methods.

Deprecation of utf8_encode() and utf8_decode().

Locale-insensitive strtolower() and strtoupper().

Signature changes in SPL methods.

Introduction of "n" modifier in PCRE library.

Changes in ODBC username and password escaping.

Deprecation of ${} string interpolation.

PHP Constants

PHP constants are names or identifiers that can't be changed during the execution of the script except for magic constants, which are not really constants. 2 ways can define PHP constants:

Using define() function

Using const keyword

Constants are similar to the variable, except once they are defined, they can never be undefined or changed. They remain constant across the entire program. PHP constants follow the same PHP variable rules. For example, it can be started with a letter or underscore only. Conventionally, PHP constants should be defined in uppercase letters.

Prevent XSS Attacks in Symfony Applications

Cross-Site Scripting (XSS) remains one of the most exploited web vulnerabilities, especially in modern PHP frameworks like Symfony. In this post, we'll explore how XSS vulnerabilities can creep into Symfony apps, how attackers exploit them, and how to fix or prevent these issues with practical code examples.

You’ll also see how you can scan your site for free using the Website Vulnerability Scanner, which helps detect XSS vulnerabilities and other issues automatically.

🔍 What is Cross-Site Scripting (XSS)?

Cross-Site Scripting (XSS) is a type of vulnerability that allows attackers to inject malicious JavaScript into webpages viewed by other users. The goal? Stealing cookies, session tokens, or redirecting users to malicious sites.

There are three common types:

Stored XSS – Malicious script is permanently stored on the target server.

Reflected XSS – Script is reflected off a web server, often in search results or error messages.

DOM-based XSS – Happens entirely on the client side using JavaScript.

⚠️ XSS in Symfony: How it Happens

Even though Symfony is a robust framework, developers may still accidentally introduce XSS vulnerabilities if they don’t properly escape output or trust user input blindly.

✅ Vulnerable Example: Output Without Escaping

// src/Controller/SampleController.php public function unsafeOutput(Request $request): Response { $name = $request->query->get('name'); return new Response("<h1>Hello, $name!</h1>"); }

If a user visits:

http://example.com?name=<script>alert('XSS')</script>

This JavaScript will execute in the browser. That’s a textbook XSS vulnerability.

🛡️ Secure Coding: Escaping Output in Symfony

Symfony uses Twig by default, which automatically escapes variables. But developers can override this behavior.

✅ Safe Example with Twig

{# templates/welcome.html.twig #} <h1>Hello, {{ name }}</h1>

This is safe because Twig escapes {{ name }} by default. But if you do this:

<h1>Hello, {{ name|raw }}</h1>

You disable escaping, making it vulnerable again. Avoid using |raw unless you're 100% sure the content is safe.

✋ Validating and Sanitizing Input

Always sanitize and validate input using Symfony’s form and validator components.

✅ Example Using Symfony Validator

use Symfony\Component\Validator\Constraints as Assert; use Symfony\Component\Validator\Validation; $validator = Validation::createValidator(); $violations = $validator->validate($userInput, [ new Assert\NotBlank(), new Assert\Regex([ 'pattern' => '/^[a-zA-Z0-9\s]*$/', 'message' => 'Only alphanumeric characters allowed.' ]), ]); if (count($violations) > 0) { // Handle validation errors }
