You can probably grab the referring page using the PHP $_SERVER array.

Specifically: HTTP_REFERER

You may need to parse the string to get the part that you need.

Some browsers may omit this field (private browsing mode, etc.), so don't forget to check for its existence: `if (isset($_SERVER['HTTP_REFERER'])) {...}` – Gras Double Oct 13 '14 at 23:38

**Note :** anybody can spoof it at anytime regardless of whether they clicked on a link or they simply don't sent it at all to begin with. [refrence](http://stackoverflow.com/questions/4662110/how-to-get-the-previous-url-using-php) – Karan Thakkar Oct 14 '14 at 05:13
