HTML:

<input type="hidden" name="link" value="http://site/see?v=12345" />

PHP:

$link = explode('=',$_POST['link']);
$link = $link[1]; // 12345

It will depend on how much your data varies, but here's a technique that will work with more complex urls:

// assuming $url = 'http://site/see?something=blah&v=ID&foo=bar'
$qs = parse_str(substr($url, strpos($url, '?')+1));
$varId = $qs['v'];

<?php
$html = 'http://site/see?v=ID';
$var-id = explode('=',$html);
$var-id = $var-id[1];
?>

You should really look at the existing answers before posting one that was already provided ;)

lol. I sometimes have my window open too long (multitasking). Don't want to steal your thunder. +1 to you. I always prefer exploding to using regex.
