get or request array problems

hi guys,

Im revisiting php for my final year project and Im forgetting or not realising silly things.

I have a collapsable / expandable list which is controlled by a variable in the query string of the URL telling the page what to keep open.

When i load the page initially I don't want to have to specify a value for the variable in the URL ie nothing is selected so why bother?

I have the following code at the top of the page:

$selected = $_REQUEST['listSel'];
if ($selected == "") {
$selected = "none";
}

it works when I have a value in the URL but not when there isnt. it causes an error. What do I need to do? I know in ASP it doesnt matter if the listSel variable isnt there in the query string.

Thanks for you help in advance.

cheers,

Something like this:

$selected = "none";
if(isset($_GET['listSel'])){
    $selected = $_GET['listSel'];
}

So the $selected will be set to none if nothing is passed through the URL (that is listSel) and if something is then $selected becomes that...

Is this even close to what you need? If it isn't please post what error you get with your code...
