ZF2 Fieldsets and Form Binding

Question

我正在尝试创建一个页面，其中包含两个字段集，每个字段集应该填充不同的表。

我可以轻松地创建一种形式作为专辑的教程，并绑定该数据是这样的：

$pageForm = new PageForm(); 
    $pageForm->bind($page); 

我PageForm类，如下所示：

class PageForm extends Form 
{ 

    public function __construct($name = null) 
    { 
     // we want to ignore the name passed 
     parent::__construct('page'); 
     $this->setAttribute('method', 'post');  


     $this->add(array(
      'name' => 'id', 
      'attributes' => array(
       'type' => 'hidden', 
      ), 
     )); 
    } /// and a bunch of other elements 

，但如果我把这些元素到字段集的绑定不再起作用，除此之外，我需要将每个字段集绑定到一个单独的表，并且一旦表单被引用，他们需要保存到单独的表中。

我该如何解决这个问题，我想我可以使用两种形式来实现，但这可能不是正确的方法（如果我正确理解fieldset的概念）？

您必须在每个Fieldset中使用setObject并为其提供水化器。例如：

<?php 
// file My/Form/Product.php 

namespace My\Form; 

use Zend\Form\Fieldset; 
use My\Entity\Product as ProductEntity; 
use Zend\Stdlib\Hydrator\ClassMethods(); 

class Product extends Fieldset 
{ 
    public function __construct($name = 'product') 
    { 
     parent::__construct($name); 
     $this->setObject(new ProductEntity()) 
      ->setHydrator(new ClassMethods()); 

     $this->add(array(
      'name' => 'name', 
      'options' => array('label' => 'Product name'), 
     )); 

     // Brand fieldset 
     $brand = new Brand(); 
     $this->add($brand); 
    } 
} 



// File My/Form/Brand.php 
namespace My\Form; 

use Zend\Form\Fieldset; 
use My\Entity\Brand as BrandEntity; 
use Zend\Stdlib\Hydrator\ClassMethods(); 

class Brand extends Fieldset 
{ 
    public function __construct($name = 'brand') 
    { 
     parent::__construct($name = 'brand'); 
     $this->setObject(new BrandEntity()) 
      ->setHydrator(new ClassMethods()); 

     $this->add(array(
      'name' => 'name', 
      'options' => array('label' => 'Brand name'), 
     )); 
    } 
} 


// File My/Form/ProductForm.php 
namespace My\Form; 

use Zend\Form\Form; 
use My\Entity\Product as ProductEntity; 
use Zend\Stdlib\Hydrator\ClassMethods(); 

class ProductForm extends Form 
{ 
    public function __construct($name = 'product') 
    { 
     parent::__construct($name); 
     $this->setObject(new ProductEntity()) 
      ->setHydrator(new ClassMethods()); 

     // Product Fieldset 
     // Here, we define Product fieldset as base fieldset 
     $product = new Product(); 
     $product->setUseAsBaseFieldset(true); 
     $this->add($product); 
    } 
} 

// In Module.php 
// ... 
    public function getServiceConfig() 
    { 
     return array(
      'invokables' => array(
       'My\Form\Product' => 'My\Form\Product', 
      ), 
     ); 
    } 
// ... 

// In Controller 
// You don't need to use $form->bind($productEntity), except if you're editing a product. 
// The form already has an Object, do you remenber??? "$this->setObject(new ProductEntity())" on form??? 

// ... 
    $form = $this->getServiceLocator()->get('My\Form\Product'); 
// ...
