PHP not recognizing GET variables with hash in the URL

Question

I have a URL like:

http://www.example.com/page.php#tabname

The hash will automatically open a specific tab on the page.

I need to work with a _GET variable, and the URL is like:

http://www.example.com/page.php#tabname?color=red

Then on the page, I have:

echo $_GET['red'];

...but I am getting an undefined index error. How do I get PHP to recognize the variable?

The # part of a url typically stays on the client - the browser doesn't send any of it to the server. You could have some javascript that queries it and sends it... — James Thorpe

Anything after the hash is not sent to the server. Regardless, you should probably format your url so you send the GET parameters correctly.

You need to put the query string before the hash:

http://www.example.com/page.php?color=red#tabname
