Undefined index errors

[Analog]

Notice: Undefined index: action in C:\wamp\www\xxx\xxx\file.php on line 24

 

I know the error is coming from $_GET['action'] being empty during the first view of the file.

So my question is....

 

Is there a way around this other than ditching the switch function and creating separate files for each case of the switch?

 

I tried this but of course still get the error...

if(!$_GET['action'])
{
	$_GET['action'] = "default";
}

You could use "isset()", http://uk.php.net/manual/en/function.isset.php

Example:

 

if(isset($_GET['action'])) { blah }

ohhh jeez....

I was really over thinking a solution to this.. lol

Never even thought about isset()

Another common way that people use is

 

$_GET['action']  = (isset($_GET['action']) && is_string($_GET['action'])) ? stripslashes(trim($_GET['action'])) : FALSE;

or disable notice reports.

That too Bertrand. Developing with error reporting set to ALL.

Thought it could improve my coding quite a bit if I try to get rid of all types of errors.
