cat[] works because for each item 'in the array cat[]' you have a
corresponding checkbox. id[] doesn't work because you only have a single
hidden element. There are more than one to resolve this:
1) Have a hidden element for each id you need to pass:- id[0], id[1], etc.
2) Use sessions
3) Use serialize() on the array $id, this allows you to store the entire array
as a single hidden element. Then use unserialize() in comp_page4.php to
reconstruct $id.
