$_POST & $_GET Question

[The_PHP_Newb]

I have some pages on my site where I need to display data coming from EITHER a form OR a URL link. This depends on where the user is coming from.

if (($POST['something'] == 1) || ($GET['something'] == 1)) {
do something
}

This seems to capture the variable being sent from both a form and a link URL and it works but again, there must be a better way?

$_REQUEST

Great thank you. Can you tell me why someone wouldn't just always use $REQUEST rather than $POST or $_GET (individually).

One example would be if you wanted to only have something posted, so it couldn't just be passed in the URL. Request also contains the cookie array, so if you didn't want that in there, you wouldn't use request. Not using it gives you more strict control over your pages and leaves less room for variable collision and hack jobs.

Much appreciated. This forum is the best!

If you want your script to accept either $POST or $GET and not be interrupted by cookie vars, use the following memory-friendly code at the beginning of your script:

if (strtolower($_SERVER['REQUEST_METHOD']) == 'get')
	$vars =& $_GET;
else
	$vars =& $_POST;

/*
   Don't forget to use 
    =&
   or else you'll copy everything.
*/
