helloise,

Please use [php] and [/php] BBCode Tags when posting code, it makes it much easier for us to help you.

To parse arrays passed from a form:


$graphic = $_POST['graphic']; // graphic[];
foreach ($graphic as $val) {
  echo 'You checked the box that has the value of: '.$val;
  echo '<br />';
}

You can repeat the following for any checkbox arrays you have.

helloise

sorry the double post was an accident... thanks but how can i get the product_id as well for those that where checked?? for instance:
foreach ($graphic as $val) {
echo 'You checked the graphic box for product: '.$product_id; ???????
echo '<br />';
}

thanks
