function i18n_book_navigation_theme in Book translation 6.2

Same name and namespace in other branches

1. 6 i18n_book_navigation.module \i18n_book_navigation_theme()
2. 7.2 i18n_book_navigation.module \i18n_book_navigation_theme()

Implementation of hook_theme()

The i18n_book_navigation uses the book-navigation.tpl.php file for theming the "footer" book navigation in book pages. It will use it to display this navigation on translated nodes, even if they're not part of a book outline. We must implement our own theme however, because the default book_navigation will call menu_tree_all_data() before i18n_book_navigation, which will store an empty tree statically, preventing us from using it and translating the links.
