menu_tree_page_data() is not loading sub-menu items

Question

I have created a menu that has a handful of top level items and some sub-menu items. it is similar in structure to my "main menu". It is my understanding that each top level menu item is an array, which also contains an array of menu items that are "below" that menu item.

When I print out the array of the menu it will not show the sub-menu items. Am I doing something wrong?

$mm = menu_tree_page_data('menu-second-menu');
print_r($mm);

My ultimate goal is creating X amount of individual menus, and display them in various places throughout the theme.

When I print the array values for the "Main Menu", which is assigned to a block and working, I do see the sub-menu items right where I'd expect them to be.

Answer 1

If you want the whole array of the menu use this function,

menu_tree_all_data('MENU_NAME');

If you find any difficulty, please let me know!

Answer 2

But isn't menu_tree_page_data() suppose to do the task as well? If it doesn't we need to know why so we can address the issue right to the cause of the problem. I am using i18n_menu_translated_tree() and apparently it is also using menu_tree_page_data() to call the menu. But due to this factor, my translated menu is not showing properly (i.e. submenu not shown).

Anyone who has knowledge on this issue kindly share. Thanks in advance.
