bascially I have a form page which uses an external page to display some of it's php so I want it to be POSTing to this page before the form is completed and sent through again through the server
$_POST is only ever set when the method is "post" you could use "$_GET" instead and append variables in pairs to the query string such as "index.php?id=34&happy=true" used as $_GET['id'] and $_GET['happy'] in the script.

You have the script you want to send data to, then a question mark, then a series of key/value pairs, with the value name on the left of the equals sign, and the value itself on the right. These pairs are separated by the ampersand (&) character.
So the above example is sending the value called foo ('hello') and the value called bar (42) to the script somescript.php.
Then in somescript.php, the data is accessible via the $_GET superglobal:
