What are the potential risks of automatically submitting a form button using JavaScript in PHP?

Automatically submitting a form button using JavaScript in PHP can lead to potential security risks such as CSRF attacks, where an attacker can trick a user into submitting a form without their knowledge. To prevent this, you can implement server-side validation to check for CSRF tokens before processing the form submission. 

<?php
// Check if the CSRF token is valid before processing the form submission
if(isset($_POST['csrf_token']) && $_POST['csrf_token'] === $_SESSION['csrf_token']) {
    // Process the form submission
    // Your code here
} else {
    // Invalid CSRF token, handle the error accordingly
    // Your code here
}
?>
