A few points that you must keep in mind....
1. If you want to limit the number of selections to the user, one way
you can do this is with JavaScript. In that case, be sure that the use
of Name and Id properties of the checkboxes is ok. For example,
usually the name of a collection of checkboxes is
NAME='checkbox_name[]' and the id can be ID='checkbox_id_1'. Why?
Because the PHP script take the value of NAME as an array with
$_POST['checkbox_name'], and some function with JavaScript can limit
the number of selected options, using the ID (must be unique!!!!).
Only the selected options are submitting to the PHP script.
2. Be careful, the Radio control only accept one selection.
3. If you are using a Select Multiple control, be sure that you are
selecting every selected option before submitting the information of
the form.
I hope this help.
Sorry for my english.....
