RE: [PHP] Multiple Select Stuff

You've got the right idea, and yes the select box is multiple-select. I was just hoping there was a way to format the array so that, at LEAST, it was the KEY that was set in the array (and not the value) so that.... instead of (for a multiple-select box): array(0=>"abc", 1=>"def"); It would be: array("def"=>1, "abc"=>0); That way, I could save myself the trouble of trying to loop through the array looking for a match, instead I could just do a if(isset($array['myselect']['def'])) Do you see what I mean?
