description:

WPML applies this hook filter on custom field values when a translation is saved either via the translation editor screen or via an XLIFF import. The custom field value is in this way made available to external themes and plugins for further manipulation before saving e.g. encoding or substitution.

Note: This hook requires the WPML Translation Management module
