POST Validation Loop

This code starts by creating an array that holds the name of various inputs being submitted via a POST.

getFormData() is then called, where the required fields are passed in. Inside the function an array is created to hold various pieces of data related to the form. $formData[‘valid’] is a boolean referencing if all data was provided and valid, $formData[‘fields’] is an array keyed by the name of the input with their respective value from the POST data, $formData[‘notValidFields’] is an array that will contain the names of any inputs that were not passed or that had non-valid data.

$requiredFields = array('field1', 'field2', 'field3', 'field4');
$formData = getFormData($requiredFields);

function getFormData($requiredFields){
   $formData = array();
   $formData['valid'] = true;
   $formData['fields'] = array();
   $formData['notValidFields'] = array();

   for($a = 0; $a < count($requiredFields); $a++){
       $field = $requiredFields[$a];
           $value = $_POST[$field];
                $formData['valid'] = false;
                $formData['notValidFields'][] = $field;
                $formData['fields'][$field] = $value;
           $formData['valid'] = false;
           $formData['notValidFields'][] = $field;
   return $formData;
