Check for $_SERVER['HTTP_REFERER']. It will return you the document refered URL. With that URL you can give the condition and disable the button.

The selected solution is wrong. This is not how to solve this problem. $_SERVER['HTTP_REFERER'] is not reliable. It can be spoofed and omitted which breaks this solution.

To prevent this you need to implement the POST/REDIRECT/GET pattern. Here is a tutorial that shows how it is done in PHP.
