How to integrate an index.php file (in which is a form) into a fan gate, so it's just visible for fans?

how to integrate an index.php file (in which is 开发者_如何学Goa form) into a fan gate (so it's just visible for fans)? I already got the fangate php file but I don't know how to integrate another php file in the fangate.

It doesn't work with " include "index.php"; " because everytime someone clicks the Send/Participate button of the form in the index.php file a new white/empty site is loading. But the index.php file works without the fan gate integration.

Has someone had the same problem or has anyone an idea what I can do to solve the problem?

An immediate solution would be to modify your fan_gate.php file so it will redirect the fans to the index.php file

However, the better solution would be to fix your form. It should work fine with include, I have several includes in my app and it works just fine. The problem is probably with your form's target (action). Change it to fan_gate.php if you use include.

If it still doesn't work, can you give me a link to the page?
