[Assigned] Product Category count are not sync

Hi,

So in a nutshell, when products are added to or removed from the ‘Current Promotion / 今期優惠’ category, the product count is not syncing correctly between Chinese and English, causing one language to show zero and the other to retain an outdated number?

In WPML if you delete the original, translation would not get deleted unless "When deleting a post, delete translations as well" is activated (this option is on WPML -> Settings -> Posts and pages synchronization -> When deleting a post, delete translations as well.

Can you check this and try then?

This change would not resolve the issue, because the setting only applies after it is activated. That means products and their translations are deleted only from the moment the setting is enabled.

If some original products were deleted before the setting was active, their translations would not be removed automatically by this change.

Does that make sense?

Can I ask you to reproduce this issue here?

This is the sandbox site where I set everything already, there are few products and categories translated also.

Let me know if you see the issue here as well, so I could check with our developers.

So to confirm, we could see this like this?

Steps to reproduce

1. Open WordPress Admin.
2. Edit or create a product in the default language.
3. Assign the product to the category “Current Promotion”.
4. Save or update the product.
5. Confirm that the product count for the category is correct in all languages.
6. Edit the same product again.
7. Remove the “Current Promotion” category from the product.
8. Save or update the product.
9. Check the category product counts in different languages.

Result

* In the default language, the category count updates correctly (for example, becomes 0).
* In the translated language, the category count does not update and retains the previous number of products.

Expected result

* Removing a product from a category should update the category product count consistently across all languages.

Let me know if I missed something.

This has been escalated to our 2nd tier team team and may take some debugging time, I'll get back to you as soon as I have any news or questions for you.

We've escalated this to our developers for permanent fix. In the meantime, you can try this:

Step 1

In
`WCML_Synchronize_Product_Data::delete_term_relationships_update_term_count`
located at:
`wp-content/plugins/woocommerce-multilingual/inc/translation-editor/class-wcml-synchronize-product-data.php`

After the following line:

$original_product_id = $this->post_translations->get_original_element( $object_id );

add:

if ( $original_product_id === null ) {
    $original_product_id = $object_id;
}

Step 2

In
`WCML_Synchronize_Product_Data::wcml_update_term_count_by_ids`
in the same file, add the following code immediately after:

if ( empty( $tt_ids_trans ) ) {
    return;
}

Insert:

if ( empty( $taxonomy ) ) {
    $term = get_term( $tt_id_trans );
    $taxonomy = $term->taxonomy;
}
