If you have multiple checkboxes with the same 'name' then you should name then with brackets, [], such as 'system[]'. This will tell PHP to make the results an array when the form is submitted. For any of the 'submit[]' checkboxes that are checked, they will be present in PHP array on the processing page. Those unchecked will not be present. Say you have the following. <input type="checkbox" name="submit[]" value="1">One <input type="checkbox" name="submit[]" value="2">Two <input type="checkbox" name="submit[]" value="3">Three If the method on your form is POST, and the user checks One and Three, then you'll have the following values in PHP on the ACTION page of the FORM. $_POST['submit'][0] ==> 1 $_POST['submit'][1] ==> 3 >From that data, though, there's no way to tell that checkbox "Two" was not checked, unless you go through and check all of the values. That's fine for small forms, but a hassle for large ones. You could also name your checkboxes like this: <input type="checkbox" name="submit[1]" value="1">One <input type="checkbox" name="submit[2]" value="2">Two <input type="checkbox" name="submit[3]" value="3">Three and if the user checks one and three again, you'll get $_POST['submit'][1] ==> 1 $_POST['submit'][3] ==> 3 Hopefully that clears some things up.
