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
