If you do it this way, how are you going to know which posts to query the database for? All you have is a series of numbers not relating to the posts at all (assuming $counter is something that starts at 0 or something and is incremented for each record in page one).

Yeah, and if for some reason you cannot use the recId in the query when doing a composite/multi one, then use your own primary key in the table (a unique integer ID field for example).

> I'm not familiar with is_array; I assume that it looks at $_POST['service'], which is an array, and the array will only contain elements that are non-empty, is that right? So the unchecked boxes won't build the array?

No. See php.net/in_array ;)
