本文实例讲述了Zend Framework教程之视图组件Zend_View用法。分享给大家供大家参考，具体如下：

Zend_View是Zend Framework的视图组件，MVC中的视图层。 Zend_View也是应用的直接对用户展示的页面。这里介绍一下Zend_View的实现类，以及如何和Controller结合在一起的。

View的实现

Zend_View的实现主要是通过如下目录的类实现：

root@coder-671T-M:/library/Zend# tree | grep View.PHP │ └── View/ ├── View.PHP

root@coder-671T-M:/library/Zend/View# tree . ├── Abstract.PHP ├── Exception.PHP ├── HelPEr │ ├── Abstract.PHP │ ├── Action.PHP │ ├── BaseUrl.PHP │ ├── Currency.PHP │ ├── Cycle.PHP │ ├── DeclareVARs.PHP │ ├── Doctype.PHP │ ├── Fieldset.PHP │ ├── FormButton.PHP │ ├── FormCheckBox.PHP │ ├── FormElement.PHP │ ├── FormErrors.PHP │ ├── FormFile.PHP │ ├── FormHidden.PHP │ ├── FormImage.PHP │ ├── ForMLabel.PHP │ ├── FormMultiCheckBox.PHP │ ├── FormNote.PHP │ ├── FormPassword.PHP │ ├── Form.PHP │ ├── FormRadio.PHP │ ├── FormReset.PHP │ ├── FormSelect.PHP │ ├── FormSubmIT.PHP │ ├── FormTextarea.PHP │ ├── FormText.PHP │ ├── Gravatar.PHP │ ├── HeadLink.PHP │ ├── HeadMeta.PHP │ ├── HeadScript.PHP │ ├── HeadStyle.PHP │ ├── HeadTitle.PHP │ ├── HtmlElement.PHP │ ├── HtmlFlash.PHP │ ├── HtmlList.PHP │ ├── HtmlObject.PHP │ ├── HtmlPage.PHP │ ├── HtmlQuickTime.PHP │ ├── InlineScript.PHP │ ├── Interface.PHP │ ├── Json.PHP │ ├── Layout.PHP │ ├── Navigation │ │ ├── Breadcrumbs.PHP │ │ ├── HelperAbstract.PHP │ │ ├── Helper.PHP │ │ ├── Links.PHP │ │ ├── Menu.PHP │ │ └── Sitemap.PHP │ ├── Navigation.PHP │ ├── paginationControl.PHP │ ├── Partial │ │ └── Exception.PHP │ ├── PartialLoop.PHP │ ├── Partial.PHP │ ├── Placeholder │ │ ├── Container │ │ │ ├── Abstract.PHP │ │ │ ├── Exception.PHP │ │ │ └── Standalone.PHP │ │ ├── Container.PHP │ │ ├── Registry │ │ │ └── Exception.PHP │ │ └── Registry.PHP │ ├── Placeholder.PHP │ ├── RenderToPlaceholder.PHP │ ├── ServerUrl.PHP │ ├── TinySrc.PHP │ ├── Translate.PHP │ ├── Url.PHP │ └── UserAgent.PHP ├── Interface.PHP └── Stream.PHP

Zend_View和Zend_Controller的整合

主要在Zend_Controller_Action类中,

getInvokearg('noVieWrenderer') && $this->_helper->hasHelper('vieWrenderer')) {
      return $this->view;
    }
    require_once 'Zend/View/Interface.PHP';
    if (isset($this->view) && ($this->view instanceof Zend_View_Interface)) {
      return $this->view;
    }
    $request = $this->getRequest();
    $module = $request->getModuleName();
    $dirs  = $this->getFrontController()->getControllerDirectory();
    if (empty($module) || !isset($dirs[$module])) {
      $module = $this->getFrontController()->getDispatcher()->getDefaultModule();
    }
    $baseDir = dirname($dirs[$module]) . DIRECTORY_SEPARATOR . 'views';
    if (!file_exists($baseDir) || !is_dir($baseDir)) {
      require_once 'Zend/Controller/Exception.PHP';
      throw new Zend_Controller_Exception('Missing base view directory ("' . $baseDir . '")');
    }
    require_once 'Zend/View.PHP';
    $this->view = new Zend_View(array('basePath' => $baseDir));
    return $this->view;
  }
  /**
   * Render a view
   *
   * Renders a view. By default,views are found in the view script path as
   * /.phtml. You may change the script suffix by
   * resetting {@link $viewSuffix}. You may omit the controller directory
   * PRefix by specifying boolean true for $noController.
   *
   * By default,the rendered contents are appended to the response. You may
   * specify the named body content segment to set by specifying a $name.
   *

   * @param string|null $name Response object named path segment to use; defaults to null

   * @return void
   */
  public function render($action = null,$name = null,$noController = false)
  {
    if (!$this->getInvokeArg('noviewrenderer') && $this->_helper->hasHelper('viewRenderer')) {
      return $this->_helper->viewRenderer->render($action,$name,$noController);
    }
    $view  = $this->initView();
    $script = $this->getViewScript($action,$noController);
    $this->getResponse()->appendBody(
      $view->render($script),$name
    );
  }
  /**
   * Render a given view script
   *
   * Similar to {@link render()},this method renders a view script. Unlike render(),* however,it does not autodetermine the view script via {@link getViewScript()},* but instead renders the script passed to it. Use this if you know the
   * exact view script name and path you wish to use,or if using paths that do not
   * conform to the spec defined with getViewScript().
   *
   * By default,the rendered contents are appended to the response. You may
   * specify the named body content segment to set by specifying a $name.
   *
   * @param string $script
   * @param string $name
   * @return void
   */
  public function renderScript($script,$name = null)
  {
    if (!$this->getInvokeArg('noViewRenderer') && $this->_helper->hasHelper('viewRenderer')) {
      return $this->_helper->viewRenderer->renderScript($script,$name);
    }
    $view = $this->initView();
    $this->getResponse()->appendBody(
      $view->render($script),$name
    );
  }
