function TaxonomyIndexTid::validate_term_strings

Validate the user string. Since this can come from either the form or the exposed filter, this is abstracted out a bit so it can handle the multiple input sources.

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.
