PHP Successfully validate then pass variables across multiple pages

[dissonantallure]

Okay I have finally figured out how to pass variables across multiple pages by using the following code.

<?php
foreach ($_POST as $key => $val) {
echo '<input type="hidden" name="' . $key . '" value="' . $val . '" />' . "\r\n";
}
?>

Now I am stuck on how to validate each field without using any JavaScript. I usually use:

<form action="<?php $_SERVER['PHP_SELF'] ?>" />

However, I cannot use that code and pass variables to the next page. Can anyone please help me successfully validate and pass form fields across several pages?

Why not use SESSION variables instead.

This is a fairly easy way of passing variables to multiple pages with no intricate code needed to access the variable values.

Have a look at how to use SESSION variables and see if that meets your requirements
