zend-form - 使用字段集时在 ZF2 中填充表单数据

Question

我目前正在玩 ZF2 beta 4，当我尝试在表单中使用字段集并在提交表单时将数据返回到表单中时，我似乎被卡住了。我不确定我是否没有为字段集设置正确的输入过滤器，或者我遗漏了什么。例如，我有以下内容(简化以使其清楚):

Controller

public function indexAction(){
   $form = new MyForm();
   $request = $this->getRequest();
          if ($request->isPost()) {
                 $form->setData($request->post());
                 if ($form->isValid()) {
                        //Do something
                        print_r($form->getData()); //for debug
                 }
          }
   return array('form' => $form);
}

MyForm.php

class MyForm extends Form
{
    public function __construct()
    {
        parent::__construct();
        $this->setName('myForm');
        $this->setAttribute('method', 'post');

        $this->add(array(
                    'name' => 'title',
                    'attributes' => array(
                    'type'  => 'text',
                    'label' => 'Title',
                    ),
                 ));

        $this->add(new MyFieldset('myfieldset'));

        //setting InputFilters here
        $inputFilter = new InputFilter();
        $factory = new InputFactory();

        $inputFilter->add($factory->createInput(array(
            'name'     => 'title',
            'required' => true,
            'filters'  => array(
                array('name' => 'StripTags'),
                array('name' => 'StringTrim'),
            ),
        )));

        //Now add fieldset Input filter
        foreach($this->getFieldsets() as $fieldset){
              $fieldsetInputFilter = $factory->createInputFilter($fieldset->getInputFilterSpecification());
              $inputFilter->add($fieldsetInputFilter,$fieldset->getName());
        }

        //Set InputFilter
        $this->setInputFilter($inputFilter);
    }
}

MyFieldset.php

class MyFieldset extends Fieldset implements InputFilterProviderInterface{
    public function __construct($name)
    {
        parent::__construct($name);
        $factory = new Factory();

        $this->add($factory->createElement(array(
            'name' => $name . 'foo',
            'attributes' => array(
                'type'  => 'text',
                'label' => 'Foo',
            ),
        )));
    }

    public function getInputFilterSpecification(){
        return array(
            'foo' => array(
                'required' => true,
                'filters'  => array(
                    array('name' => 'StripTags'),
                    array('name' => 'StringTrim'),
                ),
            ),
        );
    }
}

我能够按预期输出表单，最后得到两个名为“title”和“myfieldsetfoo”的输入元素(使用 ViewHelper 输出时给出的名称)。因此，当我提交原始帖子时，当然会显示“title”和“myfieldsetfoo”的值。但是，当我使用 SetData() 时，字段集的值未被填充(尽管我可以在原始帖子对象中看到这些值)。相反，检查我收到的“$form->getData()”的输出:

Array(
   [title] => Test,
   [myfieldset] => Array(
                         [foo] =>
                        )
)

我错过了什么？我需要做什么才能使 ZF2 了解如何填充字段集？

感谢您的帮助，这让我发疯。

Answer 1

我这样做的原因是连接 InputFilter，这样我就可以处理发布的整个 HTML 表单数组。

<form method="POST">
<input type="text" name="main[name]" />
<input type="text" name="main[location]" />
<input type="text" name="contact[telephone]" />

<input type="submit" value="Send" />
</form>

这将创建一个像 posted 这样的数组

post["main"]["name"]
post["main"]["location"]
post["contact"]["telephone"]

过滤和验证:

use Zend\InputFilter\InputFilter;
use Zend\InputFilter\Factory as InputFactory;

$post = $this->request->getPost();
$inputFilter = new InputFilter();
$factory = new InputFactory();

// $post["main"]
$mainFilter = new InputFilter();
$mainFilter->add($factory->createInput(array(
    'name'     => 'name',
    'required' => true,
    'filters'  => array(
        array('name' => 'StripTags'),
        array('name' => 'StringTrim'),
    ),
    'validators' => array(
        array(
            'name'    => 'StringLength',
            'options' => array(
                'encoding' => 'UTF-8',
                'min'      => 1,
                'max'      => 100,
            ),
        ),
    ),
    )));

$mainFilter->add($factory->createInput(array(
    'name'     => 'location',
    'required' => true,
    'filters'  => array(
        array('name' => 'StripTags'),
        array('name' => 'StringTrim'),
    ),
    'validators' => array(
        array(
            'name'    => 'StringLength',
            'options' => array(
                'encoding' => 'UTF-8',
                'min'      => 1,
                'max'      => 100,
            ),
        ),
    ),
    )));
$inputFilter->add($mainFilter, "main");

// $post["contact"]
$contactFilter = new InputFilter();
$contactFilter->add($factory->createInput(array(
    'name'     => 'name',
    'required' => true,
    'filters'  => array(
        array('name' => 'StripTags'),
        array('name' => 'StringTrim'),
    ),
    'validators' => array(
        array(
            'name'    => 'StringLength',
            'options' => array(
                'encoding' => 'UTF-8',
                'min'      => 1,
                'max'      => 100,
            ),
        ),
    ),
    )));
$contactFilter->add($mainFilter, "contact");

//Set posted data to InputFilter
$inputFilter->setData($post->toArray());
