Hello everyone,

i need for my multilanguage site a modified Menu() Function because not all subpages are going to be translated. So i need a way to display the other pages if there are not available in the current selected language.

I managed to modify the getMenu() Function in the ContentController Class that it works on Level1 Navigation. The english Fallbacks works great... BUT for the deeper Levels it aint working...

Here my modified Function so far:

public function getMenu($level = 1) {
      if($level == 1) {
         $result = Translatable::get_by_locale("SiteTree", "en_US", "\"ShowInMenus\" = 1 AND \"ParentID\" = 0");

      } else {
         $parent = $this->data();
      
         $stack = array($parent);
         
         if($parent) {
            while($parent = $parent->Parent) {
                  
               array_unshift($stack, $parent);
            }
         }
         
         if(isset($stack[$level-2])) $result = $stack[$level-2]->Children();
      }

      $visible = array();
      
      
      
      
      // Remove all entries the can not be viewed by the current user
      // We might need to create a show in menu permission
      if(isset($result)) {
         foreach($result as $page) {
            
            
            if($page->canView()) {
               
               if($page->hasTranslation(Translatable::get_current_locale())){
                  $page = $page->getTranslation(Translatable::get_current_locale());
                  $visible[] = $page;
               }else{
                  $page = $page->getTranslation('en_US');
                  $visible[] = $page;
               }
               
            }
            
         }
         
      }
      
      return new DataObjectSet($visible);
   }

As i said, i need the functionality that subpages are displayed even if they are not available in the current selected language. So that visitors will have at least the change so see/read the english pages...

Thank you in advance, any help is appreciated =)

cheers,
Alex

PS: I'm not sure if i posted this in the right section :S

EDIT::
Ok, for some super über weird reason it suddenly stopped working -..-
As soon i switch to german i get follow User Warning:

[User Warning] DataObjectSet::__construct: Passed item #6 is not an object or associative array, can't be properly iterated on in templates

Edit No.2:
Ok, it works again if i delete my other Page Classes which i hade extended from the Page Class.

cheers
