public FormValidator::executeValidateHandlers(&$form, FormStateInterface &$form_state)
Executes custom validation handlers for a given form.
Button-specific handlers are checked first. If none exist, the function falls back to form-level handlers.
$form: An associative array containing the structure of the form.
$form_state: The current state of the form. If the user submitted the form by clicking a button with custom handler functions defined, those handlers will be stored here.
Overrides FormValidatorInterface::executeValidateHandlers
public function executeValidateHandlers(&$form, FormStateInterface &$form_state) { // If there was a button pressed, use its handlers. $handlers = $form_state->getValidateHandlers(); // Otherwise, check for a form-level handler. if (!$handlers && isset($form['#validate'])) { $handlers = $form['#validate']; } foreach ($handlers as $callback) { call_user_func_array($form_state->prepareCallback($callback), array(&$form, &$form_state)); } }
