Zend FrameWork 2 Get ServiceLocator In Form and populate a drop down list

Question

I need to get the adapter from the form, but still could not.

In my controller I can recover the adapter using the following:

Answer 1

We handle this in the model, by adding a method that accepts a form

public function buildFormSelectOptions($form, $context = null)
{
    /** 
     * Do this this for each form element that needs options added
     */
    $model = $this->getServiceManager()->get('modelProject');

    if (empty($context)){
        $optionRecords = $model->findAll();
    } else {
        /**
         * other logic for $optionRecords
         */
    }

    $options = array('value'=>'', 'label'=>'Choose a Project');
    foreach ($optionRecords as $option) {
        $options[] = array('value'=>$option->getId(), 'label'=>$option->getName());
    }

    $form->get('project')->setAttribute('options', $options);
}

As the form is passed by reference, we can do something like this in the controller where the form is built:

    $builder = new AnnotationBuilder();
    $form = $builder->createForm($myEntity);
    $myModel->buildFormSelectOptions($form, $myEntity);

    $form->add(array(
        'name' => 'submitbutton',
        'attributes' => array(
            'type'  => 'submit',
            'value' => 'Submit',
            'id' => 'submitbutton',
        ),
    ));

    $form->add(array(
        'name' => 'cancel',
        'attributes' => array(
            'type'  => 'submit',
            'value' => 'Cancel',
            'id' => 'cancel',
        ),
    ));

Note: The example assumes the base form is build via annotations, but it doesn't matter how you create the initial form.
