I am using an iframe to deliver a form to a number of customer web sites. Each site needs its own thank you page outside the iframe however I'm struggling to redirect the user to these pages outside the iframe.
I've tried writing a javascript window.parent.location command to the browser from the PHP script, but I think timing issues mean that the browser doesn't always obey this.
Using header ( "location : http://www.theirsite.com/thank_you.php" ); loads the page in the iframe rather than outside the iframe.
Any ideas how to solve this would be gratefully received.
Thanks
Chris
