Question

I am creating a website and on one particular page, am wanting to send the user back to the previous page. I am fairly new to PHP/HTML and have been using some existing code for ideas and help.

The existing code uses the following method:

if (! empty($HTTP_REFERER))  {     header('Location: $HTTP_REFERER'); } else  {     header('Location: $CFG->wwwroot'); } 

However, when I use this code the HTTP_referer is always treated as empty and the user redirected to the root page. Any obvious flaws in this code?

Answer 1

You need to use:

$_SERVER['HTTP_REFERER']
