[Resolved] Single Product Layout cannot be translated

Problem:

The client was unable to translate the Single Product Layout using WPML as it would freeze and changes could not be saved. Other layouts were translating without issues.

Solution:

We identified that this issue was related to a known problem with the WoodMart theme, which has been documented here: WoodMart Fatal Error When Translating Product Layouts.

To resolve this, we recommended adding the following code to the functions.php file of the client's child theme and clearing the caches:

add_action( 'woocommerce_before_template_part', function () {
    global $product;
  
    if ( wp_is_json_request() && ! $product ) {
        $random_product = new WP_Query(
            array(
                'posts_per_page' => '1',
                'post_type'      => 'product',
            )
        );
  
        while ( $random_product->have_posts() ) {
            $random_product->the_post();
            $product_id = get_the_ID();
        }
  
        wp_reset_postdata();
  
        $product = wc_get_product( $product_id );
    }
} );

We advised the client to try translating the Product Layout again to ensure it works as expected.
