Description

ez_is_field_empty() is a Twig helper which checks if a Cont= ent item's field value is considered empty in the current language.

It returns a boolean value (true or false).

If the current language cannot be found as a translation for content, the m= ain language will be used. This behavior is identical when forcing a langua= ge.
