[Resolved] Video is not added to single product

Hi,

Welcome to WPML support. I will answer this question before the ticket is assigned to one of my colleagues.

This behavior is tied to how Woodmart and WPML handle synchronization of custom fields during translation:

When a product is first created in English (initial default), its video gallery field (woodmart_wc_video_gallery) is saved and works correctly.

Changing the site’s default language (to Greek, in your case) breaks the linkage between the original and translated entries—so the video gallery doesn’t appear unless uploaded under the new default.

WPML requires a translation relationship between the “default-language product” and its translations for custom fields marked “Copy” to propagate correctly.

How to fix it

1. Mark woodmart_wc_video_gallery custom field as Copy

- In WPML → Settings → Custom Fields Translation, set woodmart_wc_video_gallery to Copy.

- This ensures the video URL is copied to translated versions automatically

2. Re-establish translation linkage for affected products

For each product:

- Go to the default-language product (English version).

- Make and save a minor change (e.g., change or add a title).

- Open its translation in Greek (or default language view).

- Use the WPML translation editor or manual translation screen.

- Ensure the translation record shows it is linked to the default product (not “Create new”).

- Complete the translation on save. This re-establishes the link, allowing the copied field to sync.

See if it fixes the issue.

Thanks.

Thank you for your feedback.

Please test the following workaround by adding this code to the functions.php file:

// WPML Workaround for compsupp-7477
add_filter('get_post_metadata', 'wpml_compsupp7477_filter_woodmart_wc_video_gallery', 10, 4);
add_filter('woodmart_single_product_image_thumbnail_id', 'wpml_compsupp7477_translate_attachment_id', 10, 2);

function wpml_compsupp7477_filter_woodmart_wc_video_gallery($null, $object_id, $meta_key, $single) {
    
    // Target the specific meta key
    if ($meta_key !== 'woodmart_wc_video_gallery') {
        return $null;
    }

    // Prevent recursion by temporarily removing the filter
    remove_filter('get_post_metadata', 'wpml_compsupp7477_filter_woodmart_wc_video_gallery', 10);

    // Fetch the original meta value
    $video_gallery = get_post_meta($object_id, $meta_key, false);

    // Re-add the filter
    add_filter('get_post_metadata', 'wpml_compsupp7477_filter_woodmart_wc_video_gallery', 10, 4);

    // Check if we actually got an array
    if (isset($video_gallery[0]) && is_array($video_gallery[0])) {
        foreach ($video_gallery[0] as $key => $value) {
            // Apply the WPML filter to each item (video settings array key)
            $translated_key = apply_filters('wpml_object_id', $key, 'post', true);
            $video_gallery[0][$translated_key] = $value;
        }
    }

    return $video_gallery;
}

function wpml_compsupp7477_translate_attachment_id($attachment_id, $product) {
    return apply_filters('wpml_object_id', $attachment_id, get_post_type($attachment_id), true);
}

Please backup your database before making any changes.

Thank you for the update.

Could you please upload some screenshots showing the steps you followed and the results you’re seeing? Does the same issue occur if you create and test with a new product?

This will help me better understand the situation and provide the most accurate assistance.
