function i18n_book_navigation_theme in Book translation 7.2

Same name and namespace in other branches

1. 6.2 i18n_book_navigation.module \i18n_book_navigation_theme()
2. 6 i18n_book_navigation.module \i18n_book_navigation_theme()

Implements 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.

Note that, because of the way Drupal template auto-discovery works, a theme cannot override the i18n_book_navigation rendering using the book-navigation.tpl.php template. Drupal bases the template discovery on the theme key, NOT the template property. So, if a theme wishes to override the default template, it must use i18n-book-navigation.tpl.php instead.
