function views_ui_taxonomy_autocomplete_validate in Views (for Drupal 7) 8.3

Same name and namespace in other branches

1. 7.3 includes/admin.inc \views_ui_taxonomy_autocomplete_validate()

Form element validation handler for a taxonomy autocomplete field.

This allows a taxonomy autocomplete field to be validated outside the standard Field API workflow, without passing in a complete field widget. Instead, all that is required is that $element['#field_name'] contain the name of the taxonomy autocomplete field that is being validated.

This function is currently not used for validation directly, although it could be. Instead, it is only used to store the term IDs and vocabulary name in the element value, based on the tags that the user typed in.
