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,我会使用:
$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');
$form->get('address')->setValue('test address');
prev的最后一行。代码不起作用,出了什么问题?!
表单代码为:
<?php
namespace Companies\Form;
//use Zend\Form\Element;
use Zend\Form\Form;
class CompaniesForm extends Form {
public function __construct($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');
}

您可以使用Form populateValues()而不是setValue()方法来执行此操作:http://framework.zend.com/apidoc/2.3/classes/Zend.Form.Form.html#populateValues
所以在你的情况下你应该放入你的控制器:
$form = new CompaniesForm();
$addresses = array(
array(
'name' => 'address field 1 name'
),
array(
'name' => 'address field 2 name'
),
);
$form->get('address')->populateValues($addresses);
例如,您可以使用数据库中的数据生成地址数组。

好吧,似乎有些事情在这里混淆了。您尝试在EditForm
内手动分配字段值。那是......不好。
想象一个简单的表格
UserForm
textInput ("name")
textInput ("surname")
numberInput ("age")
现在您要编辑User
。所以你从数据库中获取数据
//$userData = $db->get('userdata')...
$userData = array(
'name' => 'Peter',
'surname' => 'Parker',
'age' => 23
);
要将现有值放入表单,您只需将FORM设置为此数据。
$form->setData($userData);
就是这样。在您的情况下,显然数据结构更加不同,更加困难。您必须拥有一个可以$form->bind()
的主对象,或者您需要修改使用$form->setData()
设置表单数据的数组。在你的情况下,这将是:
$data = array(
'id' => 1, // your objects id
'name' => 'someName',
'email' => 'foo@bar.baz',
'address' => array(
0 => array(
'streetName' => 'FooStreet',
'streetNumber' => 42
),
1 => array(
'streetName' => 'OofStreet',
'streetNumber' => 24
),
)
)
当您使用上述情况$form->setData($data)
时,您的表单将预先填充来自阵列的数据。当然,您必须从数据库获取数据,而不是手动编写数组。

如果要在控制器中使用getTargetElement()执行此操作,将返回集合中指定的元素或字段集。
$fieldset = $form->get('parent_fieldset');
$collection = $fieldset->get('collection');
$collectionFieldset = $collection->getTargetElement();
$collectionFieldset->get('element')->setValue($value);
