Determining the URL of an external page

[donovanh]

Hi,

I'm putting together a tracking system on my site to track visitors. It uses the <img src="track.php"... method to plant the tracker onto multiple pages.

I've got the referer part working alright but when i try to put together a "Top 10 pages" list i've hit a brick wall.

I need to establish the url of the page that contains the img statement. For example, if the file was linked from www.foo.com, with the statement 'img src="http://www.bar.com/script.php"', how can the script on www.bar.com tell that the script is being called from foo?

I've tried "$REMOTE_ADDR" and "$_SERVER['REQUEST_URI']" without any success.

Any suggestions much appreciated,

Don

$_SERVER['HTTP_REFERER'] may be your best bet.

Thanks 🙂 That works well.

Just know that not all browsers will return the referer value. ;-)
