Question

我写了几个自定义视图帮助程序，但我使用它们有点麻烦。如果我在控制器操作中添加辅助路径，如下所示：

public function fooAction()
{
    $this->view->addHelperPath('My/View/Helper', 'My_View_Helper');
}

然后我可以毫无问题地使用该路径中的视图。但是当我在bootstrap文件中添加这样的路径时：

protected function _initView()
{
    $this->view = new Zend_View();
    $this->view->doctype('XHTML1_STRICT');
    $this->view->headScript()->appendFile($this->view->baseUrl()
                                          . '/js/jquery-ui/jquery.js');
    $this->view->headMeta()->appendHttpEquiv('Content-Type',
                                       'text/html; charset=UTF-8');
    $this->view->headMeta()->appendHttpEquiv('Content-Style-Type',
                                             'text/css');
    $this->view->headMeta()->appendHttpEquiv('Content-Language', 'sk');
    $this->view->headLink()->appendStylesheet($this->view->baseUrl()
                                              . '/css/reset.css');
    $this->view->addHelperPath('My/View/Helper', 'My_View_Helper');
}

然后视图助手不起作用。这是为什么？在每个控制器动作中添加路径太麻烦了。以下是我的自定义视图助手的外观示例：

class My_View_Helper_FooBar
{
    public function fooBar() {
        return 'hello world';
    }
}

我在视图中使用它们：

<?php echo $this->fooBar(); ?>

我应该发布我的整个引导程序文件吗？

添加完整的bootstrap文件以防万一：

class Bootstrap extends Zend_Application_Bootstrap_Bootstrap
{
    protected function _initFrontController()
    {
        $this->frontController = Zend_Controller_Front::getInstance();
        $this->frontController->addModuleDirectory(APPLICATION_PATH

        Zend_Controller_Action_HelperBroker::addPath(
            'My/Controller/Action/Helper',
            'My_Controller_Action_Helper'
        );
        $this->frontController->registerPlugin(new My_Controller_Plugin_Auth());
        $this->frontController->setBaseUrl('/');
    }

    protected function _initView()
    {
        $this->view = new Zend_View();

        $this->view->headMeta()->appendHttpEquiv('Content-Type',

Answer 1

解决。我只需要在_initView（）方法的末尾添加这些行：

$viewRenderer = Zend_Controller_Action_HelperBroker::getStaticHelper('ViewRenderer'); 
$viewRenderer->setView($this->view);

Answer 2

我在_initView（）中有类似这样的内容：

 protected function _initView() {

    $view =  new Zend_View();

    #some view initialization ...

    $view->addHelperPath(APPLICATION_PATH . '/views/helpers', 'My_View_Helper');

    return $view;
}

然后在视图中我可以执行：

<?php echo $this->fooBar(); ?>

没有APPLICATION_PATH，它在我的情况下不起作用。

Answer 3

只是想一想：你确定你在引导程序中创建的视图（$ this-＆gt; view = new Zend_View（）;）与视图文件中的'$ this'相同吗？

我认为您需要将initView代码更改为以下内容：

protected function _initView()
{
  $view = new Zend_View();
  $view->doctype('XHTML1_STRICT');
  $view->headScript()->appendFile($this->view->baseUrl()
                                      . '/js/jquery-ui/jquery.js');
  $view->headMeta()->appendHttpEquiv('Content-Type',
                                   'text/html; charset=UTF-8');
  $view->headMeta()->appendHttpEquiv('Content-Style-Type',
                                         'text/css');
  $view->headMeta()->appendHttpEquiv('Content-Language', 'sk');
  $view->headLink()->appendStylesheet($this->view->baseUrl()
                                          . '/css/reset.css');
  $view->addHelperPath('My/View/Helper', 'My_View_Helper');

  return $view;
}

如果您的config.ini文件中有一些与View相关的设置，您可能想稍微更改一下代码：

protected function _initMyView()
{
   $view = $this->bootstrap('view')->getResource('view');
   ...

而不是：

protected function _initView()
{
  $view = new Zend_View();
  ....

Answer 4

您可以考虑为视图助手添加另一个init函数：

protected function _initViewHelpers()
{
     $this->bootstrap('view');
     $view = $this->getResource('view');

     $view->addHelperPath('My/View/Helper', 'My_View_Helper');
}

这样就不会覆盖内置的视图设置。

Answer 5

如果只添加$this->view->addHelperPath('My/View/Helper', 'My_View_Helper'); 在你的bootstrap中使用这种格式：

class Zend_View_Helper_FooBar extends Zend_View_Helper_Abstract {  
    public function fooBar() {
        return 'hello world';  
    }  
}
