Initial Code
function retain_post_data() {
	foreach($_POST as $key=>$index) {
		if (is_array($index) == false) {
			$index = trim($index);
			$form .= "<input name='$key' type='hidden' value='".$index."' />";
		else {
			foreach($index as $key2=>$index2) {
				if ($index2 != "") $form .= "<input name='".$key."[".$key2."]' type='hidden' value='$index2' />";
	return $form;}

Initial URL

Initial Description
I made this function to render hidden form elements in a new page based on what was sent from the last form. This function can be used to preserve input from a long multiple-page form.

What does it do:

1. Go through all the submitted POST elements.
2. Draw a loop of those POST elements into this new form (in form of hidden elements).
3. When that form submits, previous page's input is included inside this new form's submit action.

Note: Do not use the same form element name as it overwrites as it goes along.
