Trouble Inserting Checkbox Array

[eluser]lenwood[/eluser]
If I do that then I'll need to write code to store them all in one array and save them in the cat_id field of my table. Is that the right way?

In a Google search I found that I should add brackets to the name attribute so that it becomes an array. I'm just not sure what to do with it beyond that.

Code:

<input type="checkbox" name="cat_id[]" value="<?php echo $row->id; ?>" />
