Woocommerce Attributes Label Translations Are Not Showing

Resolved

Resolved in: 4.10.0

Overview of the issue

Due to malformed data saved in the database, it happens that product attribute label translations are not displayed on the product page.

Workaround

We are working on a fix for this issue, in the meanwhile, you can use the following patch, please do that only on a test site and if you are comfortable with editing PHP code and only after you have made sure you have a fully working backup of your site.

The follwoing patch is to be appllied in the file “wp-content/plugins/woocommerce-multilingual/inc/class-wcml-attributes.php” on line 379:

Replace the following code (the whole method “get_attr_label_translations”):

public function get_attr_label_translations( $product_id, $lang = false ) {
$trnsl_labels = get_post_meta( $product_id, 'attr_label_translations', true );</code>

if ( ! is_array( $trnsl_labels ) ) {
$trnsl_labels = [];
}

if ( isset( $trnsl_labels[ $lang ] ) ) {
return $trnsl_labels[ $lang ];
}

return $trnsl_labels;
}

With:

	public function get_attr_label_translations( $product_id, $lang = false ) {
		$trnsl_labels = get_post_meta( $product_id, 'attr_label_translations', true );

		$remove_empty_values = function ( $values ) {
			return wpml_collect( $values )->filter()->toArray();
		};

		if ( ! $lang && is_array( $trnsl_labels ) ) {
			return wpml_collect( $trnsl_labels )
				->map( $remove_empty_values )
				->toArray();
		}

		if ( isset( $trnsl_labels[ $lang ] ) ) {
			return $remove_empty_values( $trnsl_labels[ $lang ] );
		}

		return [];
	}
