function views_handler_filter_term_node_tid::validate_term_strings

Validate the user string. In order to handle multiple input sources, this is abstracted out a bit; since this can come from either the form, or the exposed filter.

Parameters

$form: The form which is used, either the views ui or the exposed filters.

$values: The taxonomy names which will be converted to tids.

Return value

array: The taxonomy ids fo all validated terms.
