Zf2 - 在集合内部的元素中设置值

Question

我有一个在表单中使用的集合,我知道,如果我想在普通元素中设置一个值,我使用:

$form->get('submit')->setValue('Update');

如何在"地址"字段中设置值例如"'在集合中''"我使用zend Framework 2".

$companies = $this->getCompaniesTable()->getCompanies($id);
$form = new CompaniesForm();
$form->bind($companies);
$form->get('submit')->setValue('Update');
$form->get('submit')->setValue('Update');
$form->get('address')->setValue('test address');

最后一行的上一页.代码不起作用,有什么问题？!

表单代码是:

<?php

namespace Companies\Form;

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

class CompaniesForm extends Form {

    public function __construct($name = null) {
        parent::__construct('companies');
        $this->setAttribute('method', 'post');
        $this->setAttribute('enctype', 'multipart/form-data');

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

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

        // address field
        $this->add(array(
            'type' => 'Zend\Form\Element\Collection',
            'name' => 'address',
            'options' => array(
                'count' => 1,
                'should_create_template' => false,
                'allow_add' => true,
                'template_placeholder' => '__placeholder__',
                'target_element' => array(
                    'type' => 'Companies\Form\AddressFieldset'
                )
            ),
        ));
        // address field

        // email field
        $this->add(array(
            'name' => 'email',
            'type' => 'text',
            'options' => array('label' => 'Email:'),
        ));

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

}

addressFieldset文件:

<?php

namespace Companies\Form;

use Companies\Entity\Address;
use Zend\Form\Fieldset;
use Zend\InputFilter\InputFilterProviderInterface;
use Zend\Stdlib\Hydrator\ClassMethods as ClassMethodsHydrator;

class AddressField {

    /**
     * @var string
      \ */
    protected $name;

    /**
     * @param string $name
     * @return Address
      \ */
    public function setName($name) {
        $this->name = $name;
        return $this;
    }

    /**
     * @return string
      \ */
    public function getName() {
        return $this->name;
    }

}

class AddressFieldset extends Fieldset implements InputFilterProviderInterface {

    public function __construct() {
        parent::__construct('Address');
        $this->setHydrator(new ClassMethodsHydrator(false))->setObject(new AddressField());

        $this->add(array(
            'name' => 'name',
            'options' => array(
                'label' => 'Address: '
            )
        ));
    }

    /**
     * @return array
      \ */
    public function getInputFilterSpecification() {
        return array(
            'name' => array(
                //'required' => true,
            )
        );
    }

}

您需要从表单中将集合作为元素,并获得集合的字段集列表.在你看来:

$collection = $form->get('address');
$fieldSets = $collection->getFieldsets();

// In your example you use one element as field set count = 1
// I guess you want to change field named address in your collection of the same name

$address = $fieldSets[0]->get('address');
$address->setValue('test adress');

//If you have more field sets in your collection for example count = 3 and you want this    
//value for all of them just iterate your field sets.

foreach($fieldsets as $fieldset){
    $fieldset->get('address')->setValue('test adress');
}
