View 如何在Zend Framework 2中实现应用程序/网站范围的表单？

在我的ZF2应用程序中，我有多个模块，其中一个是“搜索”。它提供了一个搜索表单、搜索逻辑和在数据库中找到的课程列表：

表单类

namespace Search\Form;

...

class CourseSearchForm extends Form {

    private $cities;

    public function __construct(array $cities) {
        parent::__construct('courseSearch');
        $this->setCities($cities);
        $this->setAttribute('method', 'post');
        $this->add(array(
            'name' => 'keyword',
            'attributes' => array(
                'type'  => 'text',
            ),
        ));
        $this->add(array(
            'name' => 'city',
            'type'  => 'Zend\Form\Element\Select',
            'options' => array(
                'label' => 'Stadt',
                'value_options' => $this->cities
            ),
        ));
        // ...
    }

    public function setCities(array $cities) {
        $this->cities = $cities;
    }

}

namespace Search\Controller;

...

class SearchController extends AbstractActionController {

    protected $courseTable;

    public function searchAction() {
        return $this->redirect()->toRoute('search-courses');
    }

    public function searchCoursesAction() {
        $form = $this->getServiceLocator()->get('Search\Form\CourseSearchForm');
        $request = $this->getRequest();
        if ($request->isPost()) {
            $courseSearchInput = new CourseSearchInput();
            $form->setInputFilter($courseSearchInput->getInputFilter());
            $form->setData($request->getPost());
            if ($form->isValid()) {
                $courseSearchInput->exchangeArray($form->getData());
                $courses = $this->getCourseTable()->findAllByCriteria($courseSearchInput);
            } else {
                $courses = null;
            }
        } else {
            $courses = null;
        }
        return new ViewModel(array(
            'form' => $form,
            'courses' => $courses,
            'cities' => $this->getServiceLocator()->get('Cache\Model\CityStorage')->getCities(),
        ));
    }

    /**
     * Gets a CourseTable object.
     * @return Search\Model\CourseTable
     */
    function getCourseTable() {
        if (!$this->courseTable) {
            $serviceLocator = $this->getServiceLocator();
            $this->courseTable = $serviceLocator->get('Search\Model\CourseTable');
        }
        return $this->courseTable;
    }

}

控制器类

namespace Search\Form;

...

class CourseSearchForm extends Form {

    private $cities;

    public function __construct(array $cities) {
        parent::__construct('courseSearch');
        $this->setCities($cities);
        $this->setAttribute('method', 'post');
        $this->add(array(
            'name' => 'keyword',
            'attributes' => array(
                'type'  => 'text',
            ),
        ));
        $this->add(array(
            'name' => 'city',
            'type'  => 'Zend\Form\Element\Select',
            'options' => array(
                'label' => 'Stadt',
                'value_options' => $this->cities
            ),
        ));
        // ...
    }

    public function setCities(array $cities) {
        $this->cities = $cities;
    }

}

namespace Search\Controller;

...

class SearchController extends AbstractActionController {

    protected $courseTable;

    public function searchAction() {
        return $this->redirect()->toRoute('search-courses');
    }

    public function searchCoursesAction() {
        $form = $this->getServiceLocator()->get('Search\Form\CourseSearchForm');
        $request = $this->getRequest();
        if ($request->isPost()) {
            $courseSearchInput = new CourseSearchInput();
            $form->setInputFilter($courseSearchInput->getInputFilter());
            $form->setData($request->getPost());
            if ($form->isValid()) {
                $courseSearchInput->exchangeArray($form->getData());
                $courses = $this->getCourseTable()->findAllByCriteria($courseSearchInput);
            } else {
                $courses = null;
            }
        } else {
            $courses = null;
        }
        return new ViewModel(array(
            'form' => $form,
            'courses' => $courses,
            'cities' => $this->getServiceLocator()->get('Cache\Model\CityStorage')->getCities(),
        ));
    }

    /**
     * Gets a CourseTable object.
     * @return Search\Model\CourseTable
     */
    function getCourseTable() {
        if (!$this->courseTable) {
            $serviceLocator = $this->getServiceLocator();
            $this->courseTable = $serviceLocator->get('Search\Model\CourseTable');
        }
        return $this->courseTable;
    }

}

/module/Search/view/Search/Search/Search-courses.phtml中的列表视图

...
<?php
$form = $this->form;
$form->setAttribute('action', $this->url('search-courses'));
$form->prepare();

echo $this->form()->openTag($form);
echo $this->formRow($form->get('keyword'));
echo $this->formRow($form->get('city'));
// ...
echo $this->formSubmit($form->get('submit'));
echo $this->form()->closeTag();
?>
<?php
if ($courses instanceof Zend\Db\ResultSet\ResultSetInterface) {
    echo $this->render('search/search/list-courses.phtml', array(
        'courses' => $courses
    ));
}
?>

。。。

现在，搜索表单应该显示在网站的每个页面上。如何实现这样的全局表单视图？是否有“标准”方法/最佳实践来做到这一点

Thx
您只需创建一个
ViewHelper
。将表单注入ViewHelper，然后渲染视图并返回它。ViewHelper本身看起来可能与ZfcUser提供的非常相似，可以通过某种方式显示它：

1.创建自己的视图辅助对象
为了激励你





2.使用插件转发
我更喜欢使用automatix，不是我干的，是社区干的。您的代码与我作为示例ViewHelper链接的内容没有什么区别，基本上只是另一个答案；）简单地做一些事情，比如回答，也许它会被认为比我的更好，你的答案也会被接受。ViewHelper的开销比
forward（）
要小得多。我忘了写的其他方法有：-部分视图-和布局变量部分仅呈现模板，它不知道表单-您不能在每个操作中对每个请求手动实例化表单。对于给定的用例，布局变量是非常错误的方法。forward（）或ViewHelper是可供选择的选项，如上所述，由于开销较小，ViewHelper更适合使用
