zf2 表单集合绑定

Question

请解释我如何将值绑定到这样的表单：

<?php

namespace ZfcAdmin\Form;

use Zend\Form\Form;
use Zend\Form\Element;

class FeelistUploadForm extends Form {
        public function __construct($objectManager) {

                parent::__construct('feelist');

                $this->setAttribute('method', 'post');
                $this->setAttribute('class', 'form');

                $fieldset = new FeelistFieldset($objectManager);
                $fieldset->setUseAsBaseFieldset(true);
                $this->add(array(
                        'type' => 'Zend\Form\Element\Collection',
                        'name' => 'feelist',
                        'options' => array(
                                'label' => 'fee list',
                                'should_create_template' => true,
                                'allow_add' => true,
                                'target_element' => $fieldset,
                        ),
                ));


                $this->add(array(
                        'name' => 'submit',
                        'type' => 'Submit',
                        'attributes' => array(
                                'value' => 'Save',
                                'id' => 'submitbutton',
                                'class' => 'button',
                        ),
                ));

        }
}

和字段集

 class FeelistFieldset extends Fieldset implements InputFilterProviderInterface {

        public function __construct($objectManager, $options = array()) {
               $this->setHydrator(new DoctrineHydrator($objectManager, 'InsurancyProduct\Entity\Feelist'))
                        ->setObject(new Feelist());
                parent::__construct('feelist');

                 $this->add(array(
                        'name' => 'id',
                        'type' => 'Hidden',
                 ));


                $this->add(array(
                        'name' => 'csv',
                        'type' => 'Zend\Form\Element\File',
                        'options' => array(
                                'label' => 'csv',
                        ),
                ));


                 $this->add(array(
                        'type' => 'text',
                        'name' => 'valid_from',
                        'options' => array(
                                'label' => 'valid from',
                        ),
                        'attributes'=> array(
                                'id' => 'validfrom',
                        ),
                 ));


        }

     public function getInputFilterSpecification()
     {
         return array(
         );
     }


 }

在我使用的控制器中

$feelist_form = new \ZfcAdmin\Form\FeelistUploadForm($objectManager);
$feelist_form->bind( new feelist());

我可以像这样在控制器中获取绑定值

                $feelist = $objectManager
                        ->getRepository('InsurancyProduct\Entity\Feelist')
                        ->findBy(array('product_id' => $id));

我不能将它绑定到表单，它是对象数组，但表单只接收单个对象。 表单当然是空的，我不知道如何将这些值绑定到表单。请不要把我发给 RFTM，我在过去 48 小时里一直在阅读它，关于 zf2 水合作用、表格等:(

或许你可以看看rlandas wrote and uploaded to github这个例子

这是一个实现经典ZendFramework2 Product-Brand-Category sample的工作项目

这是控制器的代码：
