首先，我很抱歉，因为它会有点长。但这将描述行动中的形式。所以请耐心等待！
假设你知道 ZF3 默认Application 模块。在Application 模块中创建了一些文件夹，用于分隔每个元素。您需要按如下方式创建它们。
让我们首先创建您的字段集。 Zend\Form\Fieldset 组件表示一组可重用的元素，并且依赖于 Zend\From\Form 组件。这意味着您需要将此附加到Zend\Form\Form。
module/Application/src/Form/Fieldset/YourFieldset.php
<?php
namespace Application\Form\Fieldset;
use Zend\Form\Element;
use Zend\Form\Fieldset;
class YourFieldset extends Fieldset
{
public function __construct($name = null)
{
parent::__construct('your-fieldset');
$this->add([
'name' => 'name_1',
'type' => Element\Checkbox::class,
'options' => [
'label' => 'Value 1',
'use_hidden_element' => true,
'checked_value' => 'yes',
'unchecked_value' => 'no',
],
'attributes' => [
'value' => 'no',
],
]);
// Creates others as your needs
}
}
现在我们将使用Zend\From\Form 附加从Zend\From\Fieldset 创建的字段集来创建表单。
module/Application/src/Form/YourForm.php
<?php
namespace Application\Form;
use Application\Form\Fieldset\YourFieldset;
use Zend\Form\Form;
class YourForm extends Form
{
public function __construct($name = null)
{
parent::__construct('your-form');
$this->add([
// This name will be used to fetch each checkbox from
// the CheckboxFieldset::class in the view template.
'name' => 'fieldsets',
'type' => YourFieldset::class
]);
$this->add([
'name' => 'submit',
'attributes' => [
'type' => 'submit',
'value' => 'Get Values',
'class' => 'btn btn-primary'
],
]);
}
}
我们的 from 几乎准备好了。如果我们希望它在控制器的任何操作中使用，我们需要使其可服务。所以让我们这样做吧。
更新您的模块配置文件。如果service_manager键不存在则添加如下sn-p代码，否则只更新factories和aliases键如下。
修复模块配置文件中的命名空间。
模块/Application/config/module.config.php
'service_manager' => [
'factories' => [
// Form service
Form\YourForm::class => Zend\ServiceManager\Factory\InvokableFactory::class,
// Other services
],
'aliases' => [
// Make an alias for the form service
'YourForm' => Form\YourForm::class,
],
],
现在表格可以使用了。这需要注入到我们的控制器中。当我在处理Application 模块时，我会将表单注入IndexController::class 的构造函数中。然后我们将在 IndexController::fieldsetAction() 方法中使用该表单。
module/Application/src/Controller/IndexController.php
<?php
namespace Application\Controller;
use Zend\Form\FormInterface;
use Zend\Mvc\Controller\AbstractActionController;
use Zend\View\Model\ViewModel;
class IndexController extends AbstractActionController
{
protected $YourForm;
public function __construct(FormInterface $YourForm)
{
$this->YourForm = $YourForm;
}
public function fieldsetAction()
{
$request = $this->getRequest();
$viewModel = new ViewModel(['form' => $this->YourForm]);
if (! $request->isPost()) {
return $viewModel;
}
$this->YourForm->setData($request->getPost());
if (! $this->YourForm->isValid()) {
return $viewModel;
}
$data = $this->YourForm->getData()['fieldsets'];
echo '<pre>';
print_r($data);
echo '</pre>';
return $viewModel;
}
}
由于这个控制器在其构造函数中接受参数，我们需要为这个控制器创建一个工厂（工厂创建其他对象）。
模块/Application/src/Factory/Controller/IndexControllerFactory.php
<?php
namespace Application\Factory\Controller;
use Application\Controller\IndexController;
use Interop\Container\ContainerInterface;
use Zend\ServiceManager\Factory\FactoryInterface;
class IndexControllerFactory implements FactoryInterface
{
public function __invoke(ContainerInterface $container, $requestedName, array $options = null)
{
// We get form service via service manager here
// and then inject controller's constructor
$YourForm = $container->get('YourForm');
return new IndexController($YourForm);
}
}
再一次，我们需要更新模块配置文件。这次我们将在controllers键下添加工厂如下
'controllers' => [
'factories' => [
Controller\IndexController::class => Factory\Controller\IndexControllerFactory::class,
],
],
最后，在视图模板中回显表单如下：
module/Application/view/application/index/fieldset.phtml
<h1>Checkbox Form</h1>
<?php
$form = $this->form;
$form->setAttribute('action', $this->url());
// Here is the catch, remember this name from the CheckboxForm::class
$fieldset = $form->get('fieldsets');
$name_1 = $fieldset->get('name_1');
$name_2 = $fieldset->get('name_2');
$name_3 = $fieldset->get('name_3');
$submit = $form->get('submit');
$submit->setAttribute('class', 'btn btn-primary');
$form->prepare();
echo $this->form()->openTag($form);
?>
<fieldset>
<legend>My legend value</legend>
<?= $this->formElement($name_1) ?>
<?= $this->formLabel($name_1) ?>
<?= $this->formElement($name_2) ?>
<?= $this->formLabel($name_2) ?>
<?= $this->formElement($name_3) ?>
<?= $this->formLabel($name_3) ?>
<?= $this->formSubmit($submit) ?>
</fieldset>
<?php
echo $this->form()->closeTag();
希望对您有所帮助！
