ZF2表单集合 - 筛选空记录

Question

我正在尝试如何筛选表单集合中的空记录。通过我的申请，我有两个实体，Competition和League。一场比赛可能有零或更多的联赛。所以我创建了一个竞赛表格（CompetitionForm），一个竞赛字段集合（CompetitionFieldset）和一个联盟字段集合（LeagueFieldset）。

将CompetitionFieldset添加到CompetitionForm，CompetitionFieldset使用Zend\Form\Element\Collection允许用户添加1个或更多联赛。我为下面的每个课程添加了当前的代码。

默认情况下，我想在比赛中显示了3轮联赛的输入字段，所以CompetitionFieldset内，当我添加了Zend\Form\Element\Collection项目，我计数选项设置为3

但是，如果用户没有按”为联赛提供任何数据，我想忽略他们。目前，我的数据库中创建了三个空的关联联赛。

如果我在LeagueFieldset上设置了InputFilter以使name字段成为必需字段，则表单将不会生效。

也许我应该还提到，我使用Doctrine2建模我的实体和滋润我的形式等

我敢肯定，我可以把它与一些额外的代码在我的模型中正常工作，甚至我的我处理表单的控制器，但我确定可能使用过滤器来获得更好的解决方案。

如果有人能指出我在正确的方向，将不胜感激。

非常感谢您提供的任何帮助。

我CompetitionForm

use Kickoff\Form\AbstractAdminForm; 
use Doctrine\Common\Persistence\ObjectManager; 
use DoctrineModule\Stdlib\Hydrator\DoctrineObject as DoctrineHydrator; 
use Zend\Stdlib\Hydrator\ClassMethods; 

class CompetitionForm extends AbstractAdminForm 
{ 
    public function __construct(ObjectManager $objectManager) 
    { 
     parent::__construct($objectManager, 'competition-form'); 

     $fieldset = new CompetitionFieldset($objectManager); 
     $fieldset->setUseAsBaseFieldset(true); 
     $this->add($fieldset); 

     $this->add(array(
      'name' => 'submit', 
      'attributes' => array(
       'type' => 'submit',

我CompetitionFieldset

     $this->setHydrator(new DoctrineHydrator($this->objectManager,'Kickoff\Model\Entities\Competition')) 
      ->setObject(new Competition()); 

     $this->setLabel('Competition'); 

     $this->add(array(

我LeagueFieldset

use Kickoff\Form\AbstractFieldset; 
use Kickoff\Model\Entities\League; 
use Doctrine\Common\Persistence\ObjectManager;

use Zend\InputFilter\InputFilterProviderInterface; 

class LeagueFieldset extends AbstractFieldset implements InputFilterProviderInterface 
{ 
    public function __construct(ObjectManager $objectManager) 
    { 
     parent::__construct($objectManager,'League'); 

     $this->setHydrator(new DoctrineHydrator($this->objectManager,'Kickoff\Model\Entities\League')) 
      ->setObject(new League()); 

     $this->setLabel('League'); 

     $this->add(array(
      'name' => 'name', 
      'options' => array(
       'label' => 'League name (e.g. First Qualifying Round)', 
      ), 
      'attirbutes' => array(

    public function getInputFilterSpecification() 
    { 
     return array(
      'name' => array(
       'required' => true,

     ); 
    } 

}

你需要将它传递给EntityManager的之前从请求得到的数据，即”当然。只需添加您自己的验证即可过滤空记录。您也可以提供JavaScript过滤器，以提交表单事件并在提交之前删除空字段。
