SysNotes devlog 3 - Ability to create a new profile

Welcome back to my SysNotes update! SysNotes is a system management app for people with DID, OSDD, and those who are otherwise plural.

(I will keep the intro text the same in all devlogs for context)

This devlog will be shorter than usual because I didn't want to lump it in with the next feature, which I expect will be quite long. In this devlog, I will add a way to create a new profile.

First Devlog (1) | Previous Devlog (2)

Quick Refactor before we jump in

"So I did some refactoring off-camera..." - originally, everything on the page was happening inside one component. I decided to split it up into the main page and the profile section, which is a new separate component. This will keep my code shorter and easier to maintain.

I also added a way to refer to each profile individually by their ID in the URL:

(Colin's profile is ID 4, which is shown in the URL)

I was also storing profile data as separate variables, which would be inconvenient to individually pass into the new main profile component. So I moved them all into one variable:

(old | new)

Design of the New Profile form

To be honest, I've been dreading this part since the beginning. I mean, how do I even lay this out? 💀

It is common for developers to avoid UI design because they are "coders not designers". I, for one, quite enjoy web design. Still, this task feels quite overwhelming to me. So, let's take this little mockup I made and turn it into something usable 💪

Too much stuff?

I think the biggest challenge here is the sheer number of inputs. And as the app grows, the number of inputs in this form will only increase.

The only mandatory input for a new profile is just their name. Therefore, the first step should be separating the Name field from the rest of the inputs.

The new and improved New Profile form is looking much better now:

...Yes, really! That's the whole form!

You are unlikely to know everything about an alter that has just split, so all those fields are completely unnecessary for an alter to be added to the list. Every other detail can be added later through the edit mode, where each field can be edited separately without needing one giant form.

Another big reason why I decided to forego the big form altogether is that the code for saving a new profile and the code for editing a profile would be almost exactly the same (including validation), and it wouldn't make sense to duplicate this code if I can just use it in one instance.

Saving a new profile

Let's add some validation to the input field to make sure that the user enters the name in a correct format.

As the Name is stored in the database as a string, it has the maximum length of 255 characters. Trying to save a longer name than this will cause errors, so we need to validate the input to make sure it's safe to insert into the database:

Here's what happens when I input a whole paragraph of Lorem Ipsum text and try to save it:

On the other hand, a shorter name saves just fine:

By the way, these flash messages are added in 2 ways: the success is a session message, and the error is an error stored separately by the validator. The flash messages originally have no styling, so I defined those myself using Tailwind's "@apply" for efficiency.

Once submitted, the name list automatically updates with our new profile:

(And if I click cancel it just empties the input)

Okay, let's click on Jenny's profile to see what it looks like! ...Oh

This is because the code tries to access Jenny's status, but she doesn't have one yet, she only has a name!

(When I pull the data from the database, I'm trying to access a non-existent value)

(And when I display the values I got from the database, the display may break if the value is NULL)

(This error applies to all profile fields, not just status, however the app crashes after just the first error it comes across so the remaining errors are not shown)

This can easily fixed by using PHP's "isset()" and/or "empty()" function, which checks if a variable has a value:

(I'm using a ternary operator as a more compact alternative to if-else. it basically goes: "if this condition is true ? then do it : if not, do something else")

(And here I just check if these values are not blank before rendering them)

Success, Jenny's profile shows!

Now, we just have to populate this profile with data about Jenny, and to do that we'll need to be able to edit each field. I will work on this in the next devlog, as I expect this to take quite some time.

Thanks so reading! As always, any suggestions are welcome!

SQL Injection

perhaps, the direct association with the SQLi is:

' OR 1=1 -- -

but what does it mean?

Imagine, you have a login form with a username and a password. Of course, it has a database connected to it. When you wish a login and submit your credentials, the app sends a request to the database in order to check whether your data is correct and is it possible to let you in.

the following PHP code demonstrates a dynamic SQL query in a login from. The user and password variables from the POST request is concatenated directly into the SQL statement.

$query ="SELECT * FROM users WHERE username='" +$_POST["user"] + "' AND password= '" + $_POST["password"]$ + '";"

"In a world of locked rooms, the man with the key is king",

and there is definitely one key as a SQL statement:

' OR 1=1-- -

supplying this value  inside the name parameter, the query might return more than one user.

most applications will process the first user returned, meaning that the attacker can exploit this and log in as the first user the query returned

the double-dash (--) sequence is a comment indicator in SQL and causes the rest of the query to be commented out

in SQL, a string is enclosed within either a single quote (') or a double quote ("). The single quote (') in the input is used to close the string literal.

If the attacker enters ' OR 1=1-- - in the name parameter and leaves the password blank, the query above will result in the following SQL statement:

SELECT * FROM users WHERE username = '' OR 1=1-- -' AND password = ''

executing the SQL statement above, all the users in the users table are returned -> the attacker bypasses the application's authentication mechanism and is logged in as the first user returned by the query. 

The reason for using  -- - instead of -- is primarily because of how MySQL handles the double-dash comment style: comment style requires the second dash to be followed by at least one whitespace or control character (such as a space, tab, newline, and so on). The safest solution for inline SQL comment is to use --<space><any character> such as -- - because if it is URL-encoded into  --%20- it will still be decoded as -- -.

PHP $ and $$ Variables

Understanding PHP $ Sign

The PHP parser uses the dollar sign, a reserved symbol, to figure out what you've specified as a compile-time variable. Certain words and symbols have been set aside in PHP so that the parser may analyse the code script and identify code blocks by establishing explicit rules. These guidelines, or reserved names, are a means of preventing naming conflicts between your classes, variables, and fundamental PHP functions, among other things. PHP separates itself from the rest of the string (script) using the dollar sign in its syntax. Symbols (Sigil's) were employed to display variables and their scope, drawing influence from Perl, which PHP shared many characteristics with in its early days.

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 }

🧪 Detecting XSS Automatically with a Free Tool

Want to find XSS vulnerabilities without writing a line of code?

Use the free security scanner by Pentest Testing Corp for a Website Security test. It scans your website for XSS, SQLi, Clickjacking, and many other issues.

🖼️ Screenshot of the Website Security Checker homepage

Screenshot of the free tools webpage where you can access security assessment tools.

📄 Sample XSS Detection Report

After scanning, you’ll get a detailed vulnerability report to check Website Vulnerability. Here’s a sample:

✅ Final Checklist for Preventing XSS in Symfony

✅ Use Twig’s auto-escaping.

✅ Never use |raw unless absolutely necessary.

✅ Validate user input with Symfony's Validator.

✅ Sanitize dynamic content before outputting.

✅ Scan your app regularly with tools like free.pentesttesting.com.

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.

Erweiterte Portale in FileMaker: Liste mit PHP und Web Viewer

Erweiterte Portale in FileMaker: Anlagenliste mit PHP und Web Viewer FileMaker ist ein vielseitiges Werkzeug für Datenbankanwendungen. Doch manchmal stoßen wir an technische Grenzen, wie die fehlende Möglichkeit, innerhalb eines Portals ein weiteres Portal zu platzieren. Diese Einschränkung können wir mit PHP und einem Web Viewer umgehen. In diesem Blog zeigen wir, wie du Anlagen zu einem Auftrag in einem Popover-Button darstellen kannst – inklusive interaktiver Buttons, die FileMaker-Scripts ausführen. Somit wirst Du in die Lage versetzt einen Datensatz auch in FileMaker anzusprechen und nicht nur den WebViewer zur Anzeige zu nutzen. In Meinem Beispiel, gehe ich von Aufträgen aus. Diese werden über ein Portal angezeigt. Jeder Auftrag kann mehrere Anlagen, bei meinem derzeitigen Kunden, sind es halt Anlagen im Bereich der Wasserversorgung. Das Ziel 1. Anzeigen der Anlagen eines Auftrags: Eine dynamische Liste von Anlagen, dargestellt in einem Web Viewer. 2. Interaktive Aktionen: Buttons, die ein FileMaker-Script starten, um die jeweilige Anlage anzuzeigen. Lösung: FileMaker + PHP 1. Datenübergabe von FileMaker an PHP Der erste Schritt ist, die relevanten Daten – z. B. eine Liste von Anlagen – an ein PHP-Script zu übergeben. Dies geschieht mit einem FileMaker-Script, das die Web Viewer-URL dynamisch setzt: Set Variable [ $auftragID ; Aufträge::ID ] Set Variable [ $anlagenListe ; Austauschen ( List ( Anlagen::AnlagenID ) ; "¶" ; "|" ) ] Set Variable [ $url ; "https://deine-webseite.de/anlagenanzeige.php?auftrag=" & $auftragID & "&anlagen=" & $anlagenListe ] Set Web Viewer [ Object Name: "WebViewer_Anlagen" ; URL: $url ] Es ist natürlich auch möglich dem WebViewer Dynamisch eine Globale Variable zu übergeben. Dann sage ich einfach setze Variable $$WebViewer0 $url. Nun benötigen wir natürlich noch ein PHP Script mit der beispielhaften Bezeichnung, -anlagenanzeige.php-. Dieses muss nach Erstellung auf den entsprechenden Server geladen werden. ```php <?php // Daten aus der URL übernehmen $auftragID = $_GET['auftrag'] ?? ''; $anlagenListe = $_GET['anlagen'] ?? ''; $anlagenArray = explode('|', $anlagenListe); // Sicherheitsmaßnahmen $auftragID = htmlspecialchars($auftragID, ENT_QUOTES, 'UTF-8'); $anlagenArray = array_map(function($anlage) { return htmlspecialchars($anlage, ENT_QUOTES, 'UTF-8'); }, $anlagenArray); ?> <!DOCTYPE html> Anlagen zu Auftrag <?= $auftragID ?>

body { font-family: Arial, sans-serif; margin: 20px; } .anlage { margin: 10px 0; padding: 10px; border: 1px solid #ddd; } .anlage-btn { padding: 5px 10px; background-color: #4285F4; color: white; border: none; cursor: pointer; }

Anlagen zu Auftrag <?= $auftragID ?>

<?php if (!empty($anlagenArray)): ?> <?php foreach ($anlagenArray as $anlage): ?>

Anlage ID: <?= $anlage ?>

')">Anlage öffnen

<?php endforeach; ?> <?php else: ?>

Keine Anlagen gefunden.

<?php endif; ?> function openInFileMaker(anlageID) { const fileMakerUrl = `fmp://$/DeineDatenbank?script=AnlageAnzeigen&param=${encodeURIComponent(anlageID)}`; window.location.href = fileMakerUrl; } ``` Dieses Script: • Nimmt die Anlagenliste entgegen und zerlegt sie in ein Array. • Baut eine HTML-Darstellung mit Buttons für jede Anlage. • Bindet JavaScript ein, um bei einem Klick auf den Button ein FileMaker-Script zu starten. 3. Web Viewer in FileMaker Füge einen Web Viewer in dein Layout ein und setze dessen URL mit dem oben gezeigten FileMaker-Script. Die Daten werden beim Öffnen des Popovers automatisch geladen und angezeigt. Ergebnis 1. Dynamische Anzeige: Die Anlagenliste wird aus der FileMaker-Datenbank geladen und dynamisch dargestellt. 2. Interaktive Aktionen: Ein Klick auf einen Button ruft die entsprechende Anlage direkt in FileMaker auf. Vorteile dieses Ansatzes • Dynamik: Änderungen in den Datenbankeinträgen werden sofort berücksichtigt. • Erweiterbarkeit: PHP bietet dir volle Flexibilität in der Anzeige und Funktionalität. • Nutzerfreundlichkeit: Direkte Interaktion aus dem Web Viewer heraus. Fazit Die Kombination aus FileMaker und PHP eröffnet spannende Möglichkeiten, Einschränkungen des FileMaker-Portalsystems zu umgehen. Ob für die Darstellung von Listen, Diagrammen oder interaktiven Inhalten – mit Web Viewern kannst du deine FileMaker-Lösung erheblich erweitern. In meinem Beispielbild, wird aufgrund von übergebenen Aufträgen, per Maps API eine Reihe aller in Umgebung befindlichen Aufträge angezeigt. Ein Button öffnet noch die Maps Kartenansicht, ein Button ruft ein FileMaker Script auf, übergibt per Parameter die sortierten Aufträge an FileMaker. Weiterverarbeitung ist somit jederzeit möglich. Natürlich ist auch ein Klick auf die Auftrags ID möglich, es kann dann je nach Bedarf in FileMaker weiterverarbeitet werden.

MySQL Naming Conventions

What is MySQL?

MySQL is a freely available open source Relational Database Management System (RDBMS) that uses Structured Query Language (SQL). SQL is the most popular language for adding, accessing and managing content in a database. It is most noted for its quick processing, proven reliability, ease and flexibility of use.

What is a naming convention?

In computer programming, a naming convention is a set of rules for choosing the character sequence to be used for identifiers that denote variables, types, functions, and other entities in source code and documentation.

General rules — Naming conventions

Using lowercase will help speed typing, avoid mistakes as MYSQL is case sensitive.

Space replaced with Underscore — Using space between words is not advised.

Numbers are not for names — While naming, it is essential that it contains only Alpha English alphabets.

Valid Names — Names should be descriptive of the elements. i.e. — Self-explanatory and not more than 64 characters.

No prefixes allowed.

Database name convention

Name can be singular or plural but as the database represents a single database it should be singular.

Avoid prefix if possible.

MySQL table name

Lowercase table name

MySQL is usually hosted in a Linux server which is case-sensitive hence to stay on the safe side use lowercase. Many PHP or similar programming frameworks, auto-detect or auto-generate class-based table names and most of them expect lowercase names.

Table name in singular

The table is made up of fields and rows filled with various forms of data, similarly the table name could be plural but the table itself is a single entity hence it is odd and confusing. Hence use names like User, Comment.

Prefixed table name

The table usually has the database or project name. sometimes some tables may exist under the same name in the database to avoid replacing this, you can use prefixes. Essentially, names should be meaningful and self-explanatory. If you can’t avoid prefix you can fix it using php class.

Field names

Use all above cases which include lowercase, no space, no numbers, and avoid prefix.

Choose short names no-longer than two words.

Field names should be easy and understandable

Primary key can be id or table name_id or it can be a self-explanatory name.

Avoid using reserve words as field name. i.e. — Pre-defined words or Keywords. You can add prefix to these names to make it understandable like user_name, signup_date.

Avoid using column with same name as table name. This can cause confusion while writing query.

Avoid abbreviated, concatenated, or acronym-based names.

Do define a foreign key on database schema.

Foreign key column must have a table name with their primary key.

e.g. blog_id represents foreign key id from table blog.

Avoid semantically — meaningful primary key names. A classic design mistake is creating a table with primary key that has actual meaning like ‘name’ as primary key. In this case if someone changes their name then the relationship with the other tables will be affected and the name can be repetitive losing its uniqueness.

Conclusion

Make your table and database names simple yet understandable by both database designers and programmers. It should things that might cause confusion, issues with linking tables to one another. And finally, it should be readable for programming language or the framework that is implemented.

PHP Static Variables

What is a Variable?

Variables in a program are used to store values or data that can be reused later in the code. Think of them as containers for numbers, characters, strings, memory addresses, and more. PHP has its own specific

rules for declaring and using variables:

All PHP variable names start with a dollar sign ($), followed by the variable name.

Variable names can be long and descriptive (e.g., $factorial, $even_nos) or short (e.g., $n, $x).

Variable names can contain alphanumeric characters and underscores (a-z, A-Z, 0-9, and _), but cannot begin with a number.

Constants are like variables whose values cannot change. They are also case-sensitive.

Assignment in PHP is done using the = operator. The variable is on the left, and the value or expression is on the right.

PHP is a loosely typed language, meaning you don't have to declare the type of a variable-its inferred based on the value assigned.

PHP variables are case-sensitive ($sum and $SUM are different).
