What are some potential pitfalls of using PHP scripts within an iFrame for PDF generation in an online shop?

One potential pitfall of using PHP scripts within an iFrame for PDF generation in an online shop is that it can expose sensitive data or functionality to potential security risks. To mitigate this risk, you can implement server-side validation and sanitization of user input to prevent malicious code injection. 

<?php
// Validate and sanitize user input
$input = $_POST['input'];
$sanitized_input = filter_var($input, FILTER_SANITIZE_STRING);

// Use the sanitized input to generate the PDF
// Your PDF generation code here
?>
