the DRY version

Code:

$editData = array();

foreach(array('Shortcode','ListName','InjectPassword','APIusername') as $expected)
{
   if ($this->input->post($expected)) { $editData[$expected] = $this->input->post($expected); }
}

$this->service->editService($this->input->post('service_id'), $editData);
