我正在尝试使用带有两个字段集的表单创建一个页面,每个字段集应该填充一个不同的表。

我可以像在相册教程中一样轻松地创建一个表单,并像这样绑定数据:

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

我的 PageForm 类如下:

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

但如果我将这些元素放入字段集中,则绑定不再有效,此外我需要将每个字段集绑定到单独的表,并且一旦提交表单,它们需要保存到单独的表中。

我将如何解决这个问题,我想我可以使用两种形式来做到这一点,但这可能不是正确的方法(如果我正确理解字段集的概念)?

您必须在每个 Fieldset 中使用 setObject 并为其提供水合器。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');
// ...
