Question

我在Zend_Navigation_Page_Mvc遇到了一个奇怪的问题。当我尝试渲染锚标记时，URL似乎是从页面上的另一个实例缓存的，因此href不正确。

要在我想要返回的操作中创建实例：

$request = $this->getRequest();

$back = new Zend_Navigation_Page_Mvc(
    array(
        'module'     => $request->getModuleName(),
        'controller' => $request->getControllerName(),
        'action'     => $request->getActionName(),
        'params'     => $params, // an array of params to pass
        'label'      => 'Back to listings',
        'class'      => 'back'
    )
);

然后我将其存储在会话中，然后检索它以提供back按钮。因此，在操作中，我从会话中获取实例并将其分配给视图。在视图中，我使用echo $this->navigation(new Zend_Navigation(array($this->back)));

var_dump $this->back生成此内容：

object(Zend_Navigation_Page_Mvc)[132]
  protected '_action' => string 'index' (length=5)
  protected '_controller' => string 'specialcall' (length=11)
  protected '_module' => string 'admin' (length=5)
  protected '_params' => 
    array (size=0)
      empty
  protected '_route' => null
  protected '_resetParams' => boolean true
  protected '_encodeUrl' => boolean true
  protected '_active' => boolean false
  protected '_scheme' => null
  protected '_hrefCache' => string '/digitallearning/admin/specialcall/view' (length=39)
  protected '_label' => string 'Back to listings' (length=16)
  protected '_fragment' => null
  protected '_id' => null
  protected '_class' => string 'back' (length=4)
  protected '_title' => null
  protected '_target' => null
  protected '_accesskey' => null
  protected '_rel' => 
    array (size=0)
      empty
  protected '_rev' => 
    array (size=0)
      empty
  protected '_order' => null
  protected '_resource' => null
  protected '_privilege' => null
  protected '_visible' => boolean true
  protected '_parent' => 
    object(Zend_Navigation)[130]
      protected '_pages' => 
        array (size=1)
          '00000000219cad71000000015ca8a15d' => 
            &object(Zend_Navigation_Page_Mvc)[132]
      protected '_index' => 
        array (size=1)
          '00000000219cad71000000015ca8a15d' => int 0
      protected '_dirtyIndex' => boolean false
  protected '_properties' => 
    array (size=0)
      empty
  protected '_customHtmlAttribs' => 
    array (size=0)
      empty
  protected '_pages' => 
    array (size=0)
      empty
  protected '_index' => 
    array (size=0)
      empty
  protected '_dirtyIndex' => boolean false

使用var_dump调用$this->back->getHref();会产生意外结果：

string '/digitallearning/admin/specialcall/view' (length=39)

view是当前操作，但正如您从上面的_action所看到的，它不是设置操作。

href似乎是从缓存中获取的（请参阅上面的_hrefCache）。所以我的问题是如何强制它生成href而不是从缓存中获取它？
