$_get Error handeling

error_reporting(0);

if (!$GET['file']) {
include('content.box');
}
else {
$incl = $GET['file'];
include("$incl.box");
}

I'm trying to get file from www.mydomain.com/index.php?file=filename
This works exactly like i want it to but when I load www.mydomain.com/index.php it gives an error since there is no ?file=filename in the url. I turned error reporting off but there should be a better way to not have this error shown I think? 🙂

Does anyone know how?

hmm, does an error occur when using isset() ?

I thought I posted in newbie? 😉

Actually I wouldn't know about isset() ... i'll try to check it out, wish me luck 🙂

this will work:

if (IsSet($HTTP_GET_VARS["file"]) && $HTTP_GET_VARS["file"] != "") $file = $HTTP_GET_VARS["file"];
else $file = "";

if ($file == "") { 
include('content.box'); 
} 
else { 
$incl = $file; 
include("$incl.box"); 
}

or this should work-> slightly shorter version

$file=(isset($_GET['file'])?$_GET['file']:"content";
include("$file.box");

if (IsSet($_GET['file']) && $_GET['file'] != "") {
	$file = $_GET['file'];
	}
	else {
	$file = "";
	}

if ($file == "") {
	include('content.box');
	}
	else {
	$incl = $_GET['file'];
include("$incl.box");
}

I decided to do it like this and it doesn't give me any errors saying that 'file' doens't exist. Reason I used this is because I can quite easily understand what's going on here since it's rather basic I guess... and because like this I can use it again without going here and asking again 😉

Thanks guys!

What is actually the difference between $_GET and $HTTP_GET_VARS ? The manual isn't really clear about that imo.

$HTTP_GET_VARS is becoming depreciated, along with $HTTP_POST_VARS..

the "prefered" is now $GET, and $POST.. (theres others that follow the $_xxx thing too)

I got used to using $_GET so it will not be a problem... but when you send vars with an URL (mypage.php?var=var) how do you stop these errors from showing in your page besides using isset() or error_reporting(0)?

I think that it is best that you simply use isset() or empty() before using incoming variables
