Gravity Forms Validation WordPress

Kyle answers:

Try this for 1 and 2 (you have to add the css class 'postcode' to the zip field):



add_filter('gform_validation_5', 'validate_postcode');
function validate_postcode($validation_result) {

$form = $validation_result["form"];
$current_page = rgpost('gform_source_page_number_' . $form['id']) ? rgpost('gform_source_page_number_' . $form['id']) : 1;
foreach($form['fields'] as &$field){
if(strpos($field['cssClass'], 'postcode') === false)
continue;

$field_page = $field['pageNumber'];
$is_hidden = RGFormsModel::is_field_hidden($form, $field, array());

if($field_page != $current_page || $is_hidden)
continue;

$field_value = rgpost("input_5.5");
$is_valid = is_postcode($field_value);
if($is_valid)
continue;


$validation_result['is_valid'] = false;
$field['failed_validation'] = true;
$field['validation_message'] = 'De postcode is niet correct ingevuld.';

}

$validation_result['form'] = $form;
return $validation_result;

}

function is_postcode($value) {

$is_valid = false;
