How To Populate Input With Form Data

I have a form where people enter some stuff. Then on submission it takes them to a forum page with a separate field on the page (not a gravity form generated field.)

I want to "grab" the input from one of the fields on my gravity form and then have it populate that field on the next page.

Here's what I have most recently...

$resource_url = null;
add_action('gform_after_submission_7', 'resource_submission_handler', 10, 2);
function resource_submission_handler($entry, $form){
	$GLOBALS['resource_url'] = $entry['30'];
}

Then I have this on my other page — the one I want to populate...

<input type="text" value="<?php echo $GLOBALS['resource_url']; ?>" tabindex="<?php bbp_tab_index(); ?>" name="resource_url" id="resource_url"/>

If I change "null" to something it will put that something in. But I can't get it to update based on the input of the gravity form.

Here's hoping some weekend warriors will help out! ;)

Thanks Chris!

I figured it out actually using PHP session variables. It let me do a bit "more" than I had expected to do with it.

I will post the code later — i.e. after I've slept.

@parkeast how did you populate data from gravityform into forum in bbpress?

Yes... and please feel free to do so.
