Joomla：如何获取关联菜单项的URL（多语言/从当前页面）

Question

i want to manually add a hreflang-attribute to the HTML-Head of a page.

I'm using Joomla 3.4.8 + SEBLOD component for a multilingual site. If I associate menu items of different languages, usually a "link-tag" and a "hreflang-attribute" are added to the head to make the relationship between the menu items visible for search engines.

For some reason, this tag is not added, if I'm in a list-and-search-view of the Seblod component. That's why I manually want to write the missing tags to the head.

I know how to add meta information to the head and how to get the ID of the current menu item, but I can't figure out how to get the ID (or SEO-friendly URL) of the associated menu items of my current page.

Any ideas?

I hope I described myself well... Thanks in advance!

Example: The menu item of the current page is in german language. It is associated / connected with a menu item in english language (which is showing the english version of the current page). What I need is the SEF-URL of the english menu item.

The easiest solution would be to query the active menu so you get all of the variables for the menu. The code below should return the current active route for the menu:

$app = JFactory::getApplication();
$menu   = $app->getMenu()->getActive();

$sefUrl = $menu->route;

echo '<pre>';
print_r($menu);
echo '</pre>';

echo $sefUrl;

//HERE IS THE PHP TO SET A META DYNAMICALLY IF YOU NEED IT AS WELL
$doc =& JFactory::getDocument();
$doc->setMetaData( 'tag-name', 'tag-content', true );

If the route that is being returned is not the correct route that matches your page you can check to see if the link attribute includes index.php using strpos and then concatenate that and the menu id to run through JRoute for an SEF url as well like so:

if(strpos($menu-Link,'index.php?') !== false){
    $sefUrl = JRoute::_($menu->link.'&Itemid='.$menu->id);
}

Hope this works for you.
