的Joomla 3菜单不工作

Question

活跃状态我与Joomla 3

一个问题，我让菜单使用自定义模板位于/templates/mytemplate/html/mod_menu/mainmenu.php

但当我进入菜单中的任何链接时，“活动”数组索引始终为false。

例如，CURENT页是http://localhost/about.html

和阵列中的“活跃”指数是空

Answer 1

从所述基部的外表mod_menu文件，活性属性始终通过设定为false加载菜单的助手，而是使用自己的检查来查看活动的内容。也就是说，基mod_menu.php文件设置这些值：

$list  = ModMenuHelper::getList($params); 
$base  = ModMenuHelper::getBase($params); 
$active  = ModMenuHelper::getActive($params); 
$active_id = $active->id; 
$path  = $base->tree; 

所以active_id将包含当前菜单项的ID。因此，如果你想在当前菜单中，您可以检查这样的：

foreach ($list as $i => &$item) : 
if ($item->id == $active_id) { 
     // do something with active item 
    } 
    .... 
} 

$list由主文件中设置的，所以这是在你的布局文件访问。

您还可以检查父项目在本次检查中相同的foreach循环活动项目之上：

if (in_array($item->id, $path)) {} 

从技术上讲，你可以运行第一foreach循环，并设置$item->active到true，如果你想要的。但是，那时你可能只是完成了你想要的东西！
