what variable is set

[BrainSmasher]

I got this code already

if(isset($_GET['page'])){if($_GET['page'] == ""){include("menu.php");}if($_GET['page'] == "form"){include("formular.php");}else{echo "This page doesnt exists!";}}

But now my question is how to include main.php if no variable or an other variable like ?id is set

[BrainSmasher]

someone there?

here i made your code the way i think you want iti dont really see a reason for the isset() so i did not put it in the code

<?php//include main.php if no var is selectedif(!$_GET['page']){include('main.php');}//include other pageselseif($_GET['page'] == ""){include("menu.php");}elseif($_GET['page'] == "form"){include("formular.php");}else{echo "This page doesnt excists!";}?>

if i dont use isset it gives an error

I dont get what you are asking...If those are all the things that you are checking for, then just put include("main.php") in the else statement of your code.

NVM then.I cant explain it better

do u want something like this:

if (file_exists($_GET["page"] . ".php"))	include($_GET["page"] . ".php")else	include("main.php")
