How to pass multiple variables across multiple pages?

Question

My website involves a user submitting data over several pages of forms. I can pass data submitted on one page straight to the next page, but how do I go about sending it to

Answer 1

This is my workaround of this problem: instead of manually typing in hidden input fields, I just go foreach over $_POST:

foreach ($_POST as $key => $value) {
    echo '<input type="hidden" name="' . $key . '" value="' . $value . '" />';
}

Hope this helps those with lots of fields in $_POST :)
