Framework Error

Missing required parameter 'csrf_token' in /var/www/html/user.php on line 55

What This Error Means

The CSRF (Cross-Site Request Forgery) token is a security measure to prevent malicious requests. This error occurs when a form submission is made without including the required CSRF token.

Why It Happens

This error typically happens when a form is submitted without including the CSRF token, which is usually generated by the framework's CSRF protection mechanism. The token is included in the form through a hidden input field. If the token is missing, the framework will throw an error to prevent potential security vulnerabilities.

How to Fix It

  1. 1To fix this error, you need to include the CSRF token in the form submission. Here's an example of how to do it:
  2. 2// Before (broken code)
  3. 3$form = new MyForm();
  4. 4$form->submit();
  5. 5// After (fixed code)
  6. 6$form = new MyForm();
  7. 7$form->csrf_token = $_SESSION['csrf_token'];
  8. 8$form->submit();

Example Code Solution

❌ Before (problematic code)

$form = new MyForm();
$form->submit();
✅ After (fixed code)
PHP
$form = new MyForm();
$form->csrf_token = $_SESSION['csrf_token'];
$form->submit();
