使用Fieldsets时在ZF2中填充表单数据

Question

我目前正在使用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恢复到表单中时,我似乎陷入困境.我不确定我是否没有为字段集设置输入过滤器,或者我错过了什么.例如,我有以下内容(简化为明确):

调节器

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,最终得到两个名为'title'和'myfieldsetfoo'的输入元素(使用ViewHelper输出时给出的名称).所以当然我提交原始帖子时会显示'title'和'myfieldsetfoo'的值.但是,当我使用SetData()时,字段集的值没有被填充(尽管我可以看到原始post对象中的值).相反,检查'$ form-> getData()'的输出我收到:

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

我错过了什么？我需要做什么才能让ZF2了解如何填充字段集？

谢谢你的帮助,这让我发疯.

Answer 1

我为什么要连接InputFilter所以我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>

这将创建一个贴出的数组

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

过滤并验证:

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());
