Much of this should be familiar to you from 3 This form contains a mixture of text input fields and selection lists, corresponding closely with the fields in the item database table created earlier in the chapter All the fields use the HTMLEntities and StringTrim input filters, and many of them include input validators as well In particular, notice the use of the Regex validator for validating names and telephone numbers using a custom pattern As explained in 3, the form elements are organized into display groups for greater usability, and, in a few cases, custom error messages are used as well

Zend Framework: A Beginner s Guide
The most interesting thing about this form definition in the preceding code, however, is the use of Doctrine models to populate the three selection lists Notice that the class includes three ancillary methods, getCountries(), getGrades(), and getTypes(), which internally invoke the Doctrine models created in 4 to retrieve a list of options from the corresponding master tables These options are then attached to form elements via the addMultiOption() method
Defining Controllers and Views
The action URL for the form defined in the previous section is specified as /catalog/ item/create Under standard Zend Framework naming conventions, this corresponds to ItemController::createAction in the catalog module This controller was created in 4; now it needs to be updated with the new action Here s what the code looks like:
< php class Catalog_ItemController extends Zend_Controller_Action { public function createAction() { // generate input form $form = new Square_Form_ItemCreate; $this->view->form = $form; // // // // if test for valid input if valid, populate model assign default values for some fields save to database ($this->getRequest()->isPost()) { if ($form->isValid($this->getRequest()->getPost())) { $item = new Square_Model_Item; $item->fromArray($form->getValues()); $item->RecordDate = date('Y-m-d', mktime()); $item->DisplayStatus = 0; $item->DisplayUntil = null; $item->save(); $id = $item->RecordID; $this->_helper->getHelper('FlashMessenger')->addMessage( 'Your submission has been accepted as item #' $id ' A moderator will review it and, if approved, it will appear on the site within 48 hours'); $this->_redirect('/catalog/item/success'); }
} } public function successAction()
