This happens anyway, as only the values for checked checkboxes are returned to the script -- you'll never get to see unchecked boxes. However, the way you've written the form causes a problem here: since all text boxes, but only checked checkboxes, are sent, you'll see 5 elements in the name[] and tel[] arrays (name[0] to name[4] and tel[0] to tel[4]) but only as many entries in the check[] array as there are boxes checked -- you might get, for example, check[0] and check[1], so you know 2 boxes were checked but not *which* boxes (it might have been the ones for Entry Three and Entry Five). The way to combat this is to use explicit subscripts in your form field names, like so: <p>Entry One <input type=text name=name[1]> <input type=text name=tel[1]> <input type=checkbox name=check[1] value=1> <p>Entry Two <input type=text name=name[2]> <input type=text name=tel[2]> <input type=checkbox name=check[2] value=1> <p>Entry Three <input type=text name=name[3]> <input type=text name=tel[3]> <input type=checkbox name=check[3] value=1> <p>Entry Four <input type=text name=name[4]> <input type=text name=tel[4]> <input type=checkbox name=check[4] value=1> <p>Entry Five <input type=text name=name[5]> <input type=text name=tel[5]> <input type=checkbox name=check[5] value=1> Now, you'll still get all five entries for name[] and tel[] ([1] to [5] in this instance), but you'll also helpfully get the corresponding elements of check[] for the boxes which were actually checked -- so, if only Entry Two and Entry Four are checked, you'll get check[2] and check[4] set (but no other elements of the check[] array). All you need to do is foreach() along the check array, and take action for each key that that returns you. Cheers!
