redirect needed based on query_string?

dotty

I have to redirect users based on the user ID which is passed as a URL query string, so I have something like:


if($_SERVER['QUERY_STRING'] = "PID****")
header ('Location: page1.php);
if($_SERVER['QUERY_STRING'] = "OID****")
header ('Location: page2.php);
else
header ('Location: page3.php);

where the **** are 4 digit variables - so basically any querystring beginning with PID is sent to 'page1.php' and those with OID sent to 'page2.php' and all others to a third page.

Can this be done? Anybody know?

Use the $_REQUEST method!

if($_REQUEST["PID")) {
   header ('Location: page1.php'); 
   }
else if($_REQUEST["OID")) 
   header ('Location: page2.php');
   }
else 
   header ('Location: page3.php');
   }

Any way there's an error you are not COMPARING the values! you are assigning them use == not = 😛

Dragnovich has given a good and valid reply. The actual answer to your question, of course, is yes. The ways to do it are many, mostly basic string work:

if (stristr("PID", $_SERVER['QUERY_STRING'])) {
   header("somepage.php");
} elseif (stristr("PID", $_SERVER['QUERY_STRING'])) {
   header("otherpage.php");
}

You probably could also do this with [man]strtok/man, [man]substr/man, and others...

Thank you dalecosp and Dragnovich - I'm stuck with using the query_string method as the URL is already defined and beyond my control. It is like: http://www.asite.com?OID1234 or http://www.asite.com?PID1234 and I need to send the OID's one way and the PID's another. The numbers in both strings vary.

I've tried using stings like:

if (substr("OID", $_SERVER['QUERY_STRING'])) { 
   header("Location: reg_message.php"); 
} elseif (substr("PID", $_SERVER['QUERY_STRING'])) { 
   header("Location: reg_message2.php"); 
}

but just the first redirect happens for all pages.

Have you any more suggestions?

Thanks in advance

I've found the following on the php.net site (strings) that seems to work:

$rest = substr($_SERVER['QUERY_STRING'], 0, 3); // returns "OID"

if ($rest == "OID") 
   header("Location: reg_message.php"); 
 else 
   header("Location: reg_message2.php");

Thanks for all your help guys.
