问题描述

我需要更改Zend_View_Helper_Navigation_Menu 的输出.我找到了需要修改的两个函数，并且知道如何进行所需的更改.我不知道如何让 Navigation 对象使用我的视图助手而不是 Zend .

I need to change the output of Zend_View_Helper_Navigation_Menu. I've found the two functions that I'll need to modify, and I know how to make the changes I need. What I don't know is how to make the Navigation object use my view helper instead of the Zend one.

代表我的类扩展的代码片段:

Code snippet representing my class extension:

// file /library/My/View/Helper/Navigation/Menu.php
class My_View_Helper_Navigation_Menu extends Zend_View_Helper_Navigation_Menu
{
    protected function _renderDeepestMenu(Zend_Navigation_Container $container,
                                          $ulClass,
                                          $indent,
                                          $minDepth,
                                          $maxDepth)
    {
        // modified code here
    }

    protected function _renderMenu(Zend_Navigation_Container $container,
                                   $ulClass,
                                   $indent,
                                   $minDepth,
                                   $maxDepth,
                                   $onlyActive)
    {
        // modified code here
    }
}

编辑以澄清

我想更改

元素的类并删除 EOL 和缩进.菜单视图脚本没有选项可以做到这一点，这就是我必须扩展它的原因.

I want to change the class of the <li> elements and remove the EOL and indentation. There are no options to do that with the menu view script, which is why I'll have to extend it.

在我的 Bootstrap 中初始化导航对象:

Initializing the navigation object in my Bootstrap:

$navTable = new Default_Model_Site_DbTable_Navigation();
$view = $this->getResource('view');
$view->navigation(new Zend_Navigation($navTable->getNavigation()));

在我的布局中渲染菜单:

Rendering the menu in my layout:

echo $this->navigation()->menu();

解决方案

我通过如下重命名使其工作，但我不清楚为什么我不能重载/覆盖 _Menu 类和 menu() 函数.

I got it working by renaming things as follows, but I am not clear on why I can't overload/overwrite the _Menu class and menu() function.

将类名更改为My_View_Helper_Navigation_MyMenu
在类中添加myMenu函数(return parent::menu($container);)
在布局中调用echo $this->navigation()->myMenu();

类线框:

// file /library/My/View/Helper/Navigation/MyMenu.php
class My_View_Helper_Navigation_MyMenu extends Zend_View_Helper_Navigation_Menu
{
    public function myMenu(Zend_Navigation_Container $container = null)
    {
        return parent::menu($container);
    }

    protected function _renderDeepestMenu(Zend_Navigation_Container $container,
                                          $ulClass,
                                          $indent,
                                          $minDepth,
                                          $maxDepth)
    {
        // modified code here
    }

    protected function _renderMenu(Zend_Navigation_Container $container,
                                   $ulClass,
                                   $indent,
                                   $minDepth,
                                   $maxDepth,
                                   $onlyActive)
    {
        // modified code here
    }
}
