when q is empty in ?q=something

[etrader]

I have search page in the form of search.php?q=query, as the php script calls for other files and a long process. When visiting search.php directly, the value of q is indeed null, and it makes a long loop and use lots of cpu.

 

How to kill the script or redirect to the main page when visiting search.php?

Are you using IF ELSE statments or Switch/Case for your search page?

 

If your using either, add a IF ELSE to deal with a null value for q OR add a case for a null q.

Actually, I tried IF ELSE, but it was not successful, probably due to the complicated process. I hope to find a safer way to kill the process upon direct access to search.php; something like die upon direct access for mysql

if ( !isset($_GET['q']) ) {
//throw an error message
}

Thanks for this. I think my mistake was using $q instead of $_GET['q']
