function ajax_example_node_by_author_node_autocomplete_callback in Examples for Developers 7

Autocomplete callback for nodes by title but limited by author.

Searches for a node by title given the passed-in author username.

The returned $matches array has

• key: The title, with the identifying nid in brackets, like "Some node title [3325]"
• value: the title which will is displayed in the autocomplete pulldown.

Note that we must use a key style that can be parsed successfully and unambiguously. For example, if we might have node titles that could have [3325] in them, then we'd have to use a more restrictive token.

Parameters

int $author_uid: The author username to limit the search.

string $string: The string that will be searched.
