So when using this code on my form I get the following output:

WHILE:

p2p
on
category
Revenants

PHP:
Code:
while($i = current($_POST)) {
		echo key($_POST);
		echo '<br />';
		echo $i;
		echo '<br />';
		next($_POST);
	}
Form (too long to post here): http://pastebin.com/5Gcsz42m

Why doesn't it echo all of it?
