Question

我们如何在视图中呈现表单元素，该表格元素是从控制器动态添加的？

Answer 1

我认为你想要这样的事情

在您的控制器中：

use Publicacion\Form\AlbumForm; 
use Zend\Form\Element;

class ControllerAlbum extends AbstractActionController 
{

    // example action
    public function addAction(){
        $album=new Album();
        $form=new AlbumForm();

        // create element username
        $username = new Element\Text('username');

        $username
            ->setLabel('Username')
            ->setAttributes(array('class' => 'username','size'  => '30',
            ));

        // create element password
        $password = new Element\Password('password');
        $password
            ->setLabel('Password')
            ->setAttributes(array('size'  => '30',
            ));

        $form->add($username);
        $form->add($password);

        $form->bind($album);

        $request=$this->request->getRequest();
        if($request->isPost()){
            //... doing anything
            return $this->redirect()->toRoute('album');
        }
        return new ViewModel(array('form' => $form));
    }
}

班级专辑形式：

//示例类

use Zend\Form\Form;

class AlbumForm extends Form
{
    public function __construct($name = null)
     {
         // we want to ignore the name passed
         parent::__construct('album');

         $this->add(array(
             'name' => 'id',
             'type' => 'Hidden',
         ));
         $this->add(array(
             'name' => 'title',
             'type' => 'Text',
             'options' => array(
                 'label' => 'Title',
             ),
         ));
         $this->add(array(
             'name' => 'artist',
             'type' => 'Text',
             'options' => array(
                 'label' => 'Artist',
             ),
         ));
         $this->add(array(
             'name' => 'submit',
             'type' => 'Submit',
             'attributes' => array(
                 'value' => 'Go',
                 'id' => 'submitbutton',
             ),
         ));
    }
}

视图add.phtml

<?php
$form = $this->form;
$form->setAttribute('action', $this->url('post', array('action' => 'add')));
$form->prepare();

echo $this->form()->openTag($form);
echo $this->formHidden($form->get('id'));
echo $this->formRow($form->get('title'));
echo $this->formRow($form->get('artist'));
echo $this->formRow($form->get('username'));
echo $this->formRow($form->get('password'));
echo $this->formSubmit($form->get('send'));
echo $this->form()->closeTag();
?>
