Posted by Alin Cojocaru on Feb 4th, 2008 For a "POST" form, you can validate the checkbox like this: if(isset($_POST['checkbox_name'])) { echo 'The checkbox was selected'; //Here you do whatever you want to do next. } else { echo 'The checkbox wasn't selected'; } Regarding the radio button, if you have an option like "yes" or "no", here is an example: <input type="radio" name="option" value="yes"> <input type="radio" name="option" value="no"> //processing page if($_POST['option'] == 'yes') { echo '"Yes" option was selected.'; } elseif($_POST['option'] == 'no') { echo '"No" option was selected.'; } else { echo 'None of the options were selected.'; } Good Luck POST A REPLY
