Today we have been searching for an easy and fast way to store and reuse $_POST variables over 2 pages and more without using a session. This can save you a lot of work in some cases. This possiblity is completly browser based, so there is no need for the server to re-identify a user.


Save $_POST or some other array to a hidden field by converting it to the JSON-format. Use URL-encode to make sure that there will be no encoding problems.


Decode the hidden-fields' value on the server-side. Replace the $_POST variables depending on your needs or take the new ones.


// We save previous POST values in the 'post_saver', to provide page navigation and so on
if(strlen($_POST['post_saver'])>0) {

	$previous_post_object = json_decode(urldecode($_POST['post_saver']));
	unset($_POST['post_saver']);
	
	foreach($previous_post_object as $pkey=>$pval) {
		if(strlen($_POST[$pkey]) <= 0) {
			$_POST[$pkey] = $pval;
		}
	}
}
