A form has an checkbox 'checkbox1' with just one item - yes|label (I dont want to have a 'no' item). If a user don't choose yes, I want to change the field value into 'no' for the mapping. I use following PHP code but it doesn't work (obviously the if clause?).

foreach($mappings as $mapping)
{
$data = unserialize($mapping->data);
if(strip_tags($_POST["form'"['"checkbox1"]) !== 'yes'){
$data["checkbox1"] = 'no';
}
$mapping->data = serialize($data);
}

Any help?

Problem solved with a PHP Script (called on form process)

if($_POST[0] !== 'ja'){
$_POST[0] = "nein";
}
