3. Under this line of code, add the code and delete the blank lines if copied.

The code is as follows:

/ / add required fields to judge if ($required fields) {if (preg_match (', /', $required)) {$requireds = explode (',', $required); foreach ($requireds as $field) {if ($$field=='') {showMsg ('with * is required, please fill in','- 1 'correctly); exit () } else {if ($required=='') {showMsg ('with * is required, please fill in','- 1') correctly; exit ();} / / end
