insert loop logic

Hi, Can you tell me whats the best way of doing this please? I am getting values from a form's checkboxes (eg <input type=checkbox name='id[]' value=1> <input type=checkbox name='id[]' value=2> etc) When i get these values I want to enter them into the database but 1)I should enter only the first 5 (and ignore the rest) into the database 2)it has to enter 1 record for every every "id" picked eg: if id[1], id[2],id[3] and id[4] were picked it should enter this as 4 differient records How do i do this? I have tried using a for loop but somewhere the logic is very very bad :-) and so i deleted the whole damn thing. What do you think? When replying if possible reply with a little code as am feeling braindead. Cheers, -Ryan
