This Twig helper is available as of eZ Publish 5.2 / 2013.09

Using a Field as fieldDefIdentifier argument as of eZ Publish 5.3 / 2014.03

Description

ez_is_field_empty() is a Twig helper which checks if a Content 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, main language will be used. This behavior is identical when forcing a language.

Prototype and Arguments

ez_is_field_empty( eZ\Publish\Core\Repository\Values\Content\Content content, eZ\Publish\API\Repository\Values\Content\Field|string fieldDefIdentifier[, string forcedLanguage] )

Argument name	Type	Description
`content`	`eZ\Publish\Core\Repository\Values\Content\Content`	Content object the displayable field belongs to.
`fieldDefIdentifier`	`eZ\Publish\API\Repository\Values\Content\Field or string`	The field we want to check or its identifier.
`forcedLanguage`	`string`	Locale we want the content name translation in (e.g. "fre-FR"). Null by default (takes current locale)
