WPML GraphQL – Cannot Retrieve Translated Author Metadata

Overview of the Issue

If your are employing the WPGraphQL extension, you will notice that for already translated author metadata content, such as first names, WPGraphQL queries continue to return data in the default language.

Workaround

Please, make sure of having a full site backup of your site before proceeding.

• Open the …/wp-content/plugins/wp-graphql/src/Model/User.php file.
• Look for line 191.
• Replace:

  'firstName'                => function () {
  	return ! empty( $this->data->first_name ) ? $this->data->first_name : null;
  },

• With:

  'firstName'                => function () {
  
  	// WPML Workaround for compsupp-7323
  	if ( class_exists('SitePress') ) {
  		$post_language_details = apply_filters( 'wpml_post_language_details', NULL, $this->global_post->ID ) ;
  		$this->data->first_name = apply_filters('wpml_translate_single_string', $this->data->first_name , 'Authors', 'first_name_'.$this->data->ID);
  	}
  
  	return ! empty( $this->data->first_name ) ? $this->data->first_name : null;
  },
