function hook_content_taxonomy_tree_callback_alter in Content Taxonomy 7

Alter the term tree callback that is used for content taxonomy options lists.

By default taxonomy_get_tree is used to retrieve the list of terms. It is important that any provided tree callback must have the same function signature as hook_content_taxonomy_tree_callback_alter(). For example this hook can be used to exchange the callback with a language specific tree function.

Parameters

$tree_callback: The current callback that can be overridden.

$field: The term reference field info array.

$vocabulary: The vocabulary object for which the term list should be retrieved. One field can have multiple vocabularies attached, which leads to multiple invocations of this function.
