are you talking about
<input type="text" id="items[]" name="name1" />
<input type="text" id="items[]" name="name2" />
<input type="text" id="items[]" name="name2" />
I think thats how you do it, ive not used it in a while. if its not that, it might be name and id the other way around.
then $_POST['items'] is an array
