Re: newbie... - undefined var

Or, perhaps, you should do: (if register_globals off) if (!isset($_GET['vw'])){ echo "variable is not set"; } Of course, you can also do: (if you want to--for some reason) if ($_GET['vw'] == ""){ write this code } - E PS

Do all vars in PHP have to be defined first?

No.

BUT on the index.php I want to write this if statement: if ($vw == "") { write this code }

If you really mean to see if the variable has been set, try this instead: if (!isset($vw)) {

    echo "variable is not set";
