Same name and namespace in other branches

1. 5 taxonomy_super_select.module \_tss_next_nested()

Recursive function to allow infinite depth vocabularies.

Parameters

array &$terms The result of taxonomy_get_tree for the vocabulary's $vid.:

array &$vid The vocabulary to work on. Passed by reference just to keep overhead: of copies down.

array &$input The portion of the vocabulary to look at (parent_type?). Passed by: reference just to keep overhead of copies down.

array $tss These are the settings for this module.:

array &$form_node This is a subsection of $form, namely $form['#node'] should be: passed in.

array &$form_branch This is a subsection of $form. Each iteration adds to the one: before, then passes itself as the new branch. _tss_branch() is called for each iteration and appended to it.

Return value

since values are passed in via reference, no return value is required.
