Add Symlinks to Organic Group(s) menu(s)

don't hardcode the menu naming structure, any menu can be enabled as an og_menu

Here's an approach to the patch that's working for us.

  $nids = array();
  
  if(!empty($node->group_group[LANGUAGE_NONE])) {
    $nids[] = $node->nid; 
  }
  
  foreach ($node->og_group_ref[LANGUAGE_NONE] as $gid) {
    $nids[] = $gid['target_id'];
  }
  
  if(!empty($nids)) {  
    $result = db_query('SELECT menu_name FROM {og_menu} WHERE gid IN(:nids) ORDER By weight', array(':nids' => $nids));
    
    foreach ($result as $og_menu) {
      $menus[] = $og_menu->menu_name;
    }

    $wanted_menus = array_intersect_key(menu_get_menus(), array_flip($menus));
    $original_item = $item;
    $mpos = menu_parent_options($wanted_menus, $item, NULL);
    $item = $original_item;
    foreach ($mpos as $og_menu_key => $og_menu_value) {
      $menu_parent_options[$og_menu_key] = $og_menu_value;
    }
    // Checks if menu and parent values exist.
    if (isset($item['menu_name']) && isset($item['plid'])) {
      // Sets default parent item.
      $menu_default_parent = "{$item['menu_name']}:{$item['plid']}";
      // Checks if item is new.
    } elseif (array_key_exists('new_item', $item)) {
      if ($item['new_item'] === TRUE) {
        if (is_array($menu_default_parent)) {
          // Sets menu parent options array to first element.
          reset($mpos);
          // Sets menu default parent to first menu option.
          $menu_default_parent = key($mpos);
        }
      }
    }    
  }

A revised version that captures the create phase...

if(module_exists('og_menu')) {
    global $user;

    $nids = array(
    
    $groups = og_menu_get_node_groups('user', $user);
  
    if(!empty($groups)) {
      foreach($groups as $group) {
        $nids[] = $group;
      }
    }
      
    if(!empty($nids)) {  
      $result = db_query('SELECT menu_name FROM {og_menu} WHERE gid IN(:nids) ORDER By weight', array(':nids' => $nids));
  
      foreach ($result as $og_menu) {
        $menus[] = $og_menu->menu_name;
      }
  
      $wanted_menus = array_intersect_key(menu_get_menus(), array_flip($menus));
      $original_item = $item;
      $mpos = menu_parent_options($wanted_menus, $item, NULL);
      $item = $original_item;
      
      foreach ($mpos as $og_menu_key => $og_menu_value) {
        $menu_parent_options[$og_menu_key] = $og_menu_value;
      }
      
      // Checks if menu and parent values exist.
      if (isset($item['menu_name']) && isset($item['plid'])) {
        // Sets default parent item.
        $menu_default_parent = "{$item['menu_name']}:{$item['plid']}";
        // Checks if item is new.
      } elseif(array_key_exists('new_item', $item)) {
        if ($item['new_item'] === TRUE) {
          if (is_array($menu_default_parent)) {
            // Sets menu parent options array to first element.
            reset($mpos);
            // Sets menu default parent to first menu option.
            $menu_default_parent = key($mpos);
          }
        }
      }    
    }
  }

This patch is the same as the one in #6, but with the appropriate number of subdirectories so that `drush make` can auto-apply it.

The patch in #10 was occasionally resulting in these warnings:

Notice: Undefined property: stdClass::$og_group_ref in _nodesymlinks_form_field() (line 229 of .../sites/all/modules/contrib/nodesymlinks/nodesymlinks.inc).
Warning: Invalid argument supplied for foreach() in _nodesymlinks_form_field() (line 229 of .../sites/all/modules/contrib/nodesymlinks/nodesymlinks.inc).

The attached patch addresses this.
