Trapping Undefined Indicies

[IWP506]

Hey, here's some code:

switch ($_GET["content"]) {
case "1":
include("./1_content.html");
break;
case "2":
include("./2_content.html");
break;
default:
echo("nothing!");
}

That works perfectly... But what can I do about having the page not
show undefined index errors if they don't insert ?content= at the end
of the address?

Thanks,

use the isset() function to test if $_GET['content'] is set
before you do your switch statement. See

You don't even have to use switch:

if (isset($_GET['content']) &&
file_exists("./{$_GET['content']}_content.html")) {
include "./{$_GET['content']}_content.html";
} else {
print 'Nothing!';
}
