Question

Is there a better way of doing this?

I have a simple form with 30 check boxes.
If they are not checked, as far as PHP is concerned they don’t exist (not set), so I am setting the value to 0 as I am updating a database directly below this code:

if(!isset($_POST['checkbox1'])) {
   $_POST['checkbox1'] = '0';
}

if(!isset($_POST['checkbox2'])) {
   $_POST['checkbox2'] = '0';
}

if(!isset($_POST['checkbox3'])) {
   $_POST['checkbox3'] = '0';
}

If they are checked the value is 1 so that part is fine.

I tried playing around with this but to no avail:

foreach($_POST AS $key=>$value) {
    if($value != '1') { $_POST[$key] = '0'; }
}

How about

foreach (array('checkbox1', 'checkbox2', 'checkbox3') as $k) {
    if (!isset($_POST[$k])) {
        $_POST[$k] = '0';
    }
}
