I have a question on how to know where this $_GET value come from
$book = isset($_GET['book']) ? $_GET['book'] : null;
The problem is that this site that i am working with, has too many pages and its hard to find it, im trying to solve an error dealing with the $_GET value but first I need to know where it is comming from. Any suggestion? Thanks
With $_SERVER["HTTP_REFERER"] you will get the URL of the page that was opened before getting to your actual page. Use this to know where the people come from.
Search the page manually and comment it in the php file it's the best way I could think off this is why you can comment out in languages its there and not for nothing...
