WooCommerce Snippet

Set different language for some WooCommerce products

You might need to change the default language for some of your products written in another language. Assuming you have a shop category designated for this different language, you could use the following snippet:

// Add a filter to modify the language attributes
add_filter('language_attributes', function($lang) {
    // Check if the current page is a single product page
    if(is_product()) {
        // Retrieve the product categories
        $terms = get_the_terms(get_the_ID(), 'product_cat');
        // Loop through each category
        foreach($terms as $term) {
            // Check if the category slug matches 'czech-products'
            if($term->slug == 'czech-products') {
                // If a match is found, replace 'en-GB' with 'cs' in the language attributes
                $lang = str_replace('en-GB', 'cs', $lang);
                // Break the loop as we found the category we were looking for
    // Return the modified (or unmodified) language attributes
    return $lang;
