What are the potential pitfalls of using JavaScript onclick events to open hidden forms in PHP applications?

Using JavaScript onclick events to open hidden forms in PHP applications can lead to accessibility issues for users who have JavaScript disabled or unavailable. To ensure that all users can access the forms, it's better to use PHP to control the visibility of the forms based on user interactions. This can be achieved by using PHP to generate the necessary HTML elements with appropriate visibility settings. 

<?php
$showForm = false;

if(isset($_POST['show_form'])){
    $showForm = true;
}

?>

<!DOCTYPE html>
<html>
<head>
    <title>Hidden Form Example</title>
</head>
<body>
    <?php if($showForm): ?>
        <form action="process_form.php" method="post">
            <!-- Form fields go here -->
        </form>
    <?php else: ?>
        <button onclick="document.getElementById('hidden_form').style.display = 'block';">Show Form</button>
    <?php endif; ?>
</body>
</html>
