PHP Code:

$request = \Config\Services::request();

// leave PropertyName blank to get all properties.
$data = $request->getPost('PropertyName'); 


Code:

$request = \Config\Services::request();
$priority_array = $request->getPost('priority');
$id_array = $request->getPost('id');
$temp = array_combine($id_array, $priority_array);
print_r($temp);
