汽车导航空白链接按钮，跟我的老板正在寻找在导航栏设置一个导航链接，不是页面本身三个不同的父页面

Question

Image to describe issue better

，而是显示器显示下拉下拉列表中有3个单独的父页面（www.website.com/turkey，/ greece，/ italy）。他希望保留新网站的网址结构以避免过度的重定向，这个问题对我来说是个问题，我可以尝试自己解决。

Auto Nav本身使用php来根据网站结构生成导航栏，所以在没有任何php编辑的情况下合并这个导航栏的唯一方法就是使链接成为一个页面（而不仅仅是我的老板想要的空白链接） ，但是它破坏了他想要遵循的url文件结构。

我认为这将不得不在PHP中解决，但我不是很精通它自己，所以真的很感谢一些指导！

道歉，如果有点不清楚，如果需要更清晰，请让我知道！

/** 
* The $navItems variable is an array of objects, each representing a nav menu item. 
* It is a "flattened" one-dimensional list of all nav items -- it is not hierarchical. 
* However, a nested nav menu can be constructed from this "flat" array by 
* looking at various properties of each item to determine its place in the hierarchy 
* (see below, for example $navItem->level, $navItem->subDepth, $navItem->hasSubmenu, etc.) 
* 
* Items in the array are ordered with the first top-level item first, followed by its sub-items, etc. 
* 
* Each nav item object contains the following information: 
* $navItem->url  : URL to the page 
* $navItem->name  : page title (already escaped for html output) 
* $navItem->target  : link target (e.g. "_self" or "_blank") 
* $navItem->level  : number of levels deep the current menu item is from the top (top-level nav items are 1, their sub-items are 2, etc.) 
* $navItem->subDepth : number of levels deep the current menu item is *compared to the next item in the list* (useful for determining how many <ul>'s to close in a nested list) 
* $navItem->hasSubmenu : true/false -- if this item has one or more sub-items (sometimes useful for CSS styling) 
* $navItem->isFirst : true/false -- if this is the first nav item *in its level* (for example, the first sub-item of a top-level item is TRUE) 
* $navItem->isLast  : true/false -- if this is the last nav item *in its level* (for example, the last sub-item of a top-level item is TRUE) 
* $navItem->isCurrent : true/false -- if this nav item represents the page currently being viewed 
* $navItem->inPath  : true/false -- if this nav item represents a parent page of the page currently being viewed (also true for the page currently being viewed) 
* $navItem->attrClass : Value of the 'nav_item_class' custom page attribute (if it exists and is set) 
* $navItem->isHome  : true/false -- if this nav item represents the home page 
* $navItem->cID  : collection id of the page this nav item represents 
* $navItem->cObj  : collection object of the page this nav item represents (use this if you need to access page properties and attributes that aren't already available in the $navItem object)

/** For extra functionality, you can add the following page attributes to your site (via Dashboard > Pages & Themes > Attributes): 
* 
* 1) Handle: exclude_nav 
* (This is the "Exclude From Nav" attribute that comes pre-installed with concrete5, so you do not need to add it yourself.) 
* Functionality: If a page has this checked, it will not be included in the nav menu (and neither will its children/sub-pages). 
* 
* 2) Handle: exclude_subpages_from_nav 
* Type: Checkbox 
* Functionality: If a page has this checked, all of that pages children (sub-pages) will be excluded from the nav menu (but the page itself will be included). 
* 
* 3) Handle: replace_link_with_first_in_nav 
* Type: Checkbox 
* Functionality: If a page has this checked, clicking on it in the nav menu will go to its first child (sub-page) instead. 
* 
* 4) Handle: nav_item_class 
* Type: Text 
* Functionality: Whatever is entered into this textbox will be outputted as an additional CSS class for that page's nav item (NOTE: you must un-comment the "$ni->attrClass" code block in the CSS section below for this to work).

Answer 1

我建议只需添加一个特殊的配置，以ammend汽车导航菜单的类似链接如下：

$navItems = $controller->getNavItems(); 

$special_config = array(
    "www.website.com/turkey" /* url */=> array("level" => 2), 
    "www.website.com/greece" /* url */=> array("level" => 2) 
    // .. rest special config here 
); 

foreach ($navItems as &$navItem) 
{ 
    if (isset($special_config[$navItem->url])) 
    { 
      foreach ($special_config[$navItem->url] as $k=>$v) 
      { 
       // adjust navItem params as needed here by key=>value 
       $navItem->{$k} = $v; 
      } 
    } 
} 

// rest code follows 
// ... 

你甚至可以使一个功能ammend_nav_menu这样的：

function ammend_nav_menu($special_config, &$navItems) 
{ 
    foreach ($navItems as &$navItem) 
    { 
     if (isset($special_config[$navItem->url])) 
     { 
       foreach ($special_config[$navItem->url] as $k=>$v) 
       { 
        // adjust navItem params as needed here by key=>value 
        $navItem->{$k} = $v; 
       } 
     } 
    } 
} 

以及原样使用：

$navItems = $controller->getNavItems(); 
ammend_nav_menu(array(
    "www.website.com/turkey" /* url */=> array("level" => 2), 
    "www.website.com/greece" /* url */=> array("level" => 2) 
    // .. rest special config here 
), $navItems); 

修正菜单的特殊配置甚至可以在一个单独的php文件中，并根据需要加载/更新
