What are the advantages and disadvantages of using hidden fields to track form submission status in PHP?

Using hidden fields to track form submission status in PHP can be advantageous because it allows for a simple and straightforward way to pass data between form submissions. However, it can also be a security risk as the data stored in hidden fields can be manipulated by users. Additionally, hidden fields can clutter the HTML code and make it harder to maintain. 

<?php
// Check if form is submitted
if ($_SERVER["REQUEST_METHOD"] == "POST") {
    // Check if hidden field is set
    if(isset($_POST['form_submitted'])) {
        // Process form data
        // Redirect or display success message
    } else {
        // Handle invalid form submission
    }
}
?>

<form method="post" action="">
    <!-- Hidden field to track form submission status -->
    <input type="hidden" name="form_submitted" value="1">
    
    <!-- Other form fields -->
</form>
