You cannot have anything in the brackets for the name in a checkbox group. The brackets specify that it is an array. The name of the array is the key in $_POST that contains the values of the checkbox group that were checked. You can have as many groups as you like.

Eh? Course you can. <form method="post" action="<?php echo $_SERVER['PHP_SELF']; ?>"> <input type="checkbox" name="data[field_name][]" id="my_checkbox_1" value="1" > Val 1 <input type="checkbox" name="data[field_name][]" id="my_checkbox_2" value="2" > Val 2 <input type="checkbox" name="data[field2][]" id="field1" value="1" > Val 1 (Field 1) <input type="checkbox" name="data[field2][]" id="field2" value="2" > Val 2 (Field 2) <input type="submit"> </form> <pre> <?php print_r($_POST); You end up with a multi-dimensional array. Array (

    [data] => Array
        (
            [field_name] => Array
                (
                    [0] => 1
                )

            [field2] => Array
                (
                    [0] => 1
                    [1] => 2
                )

        )
