Filtering out specific meta keys for order line items?
-
Hello, I’m trying to remove specific meta keys from the generated invoices/package slips for each order line item. I see the code gets all meta data in
get_order_items
through$data['meta'] = wc_display_item_meta( $item, array( 'echo' => false, ) );It’s possible to filter out specific meta keys with the filter
woocommerce_order_item_get_formatted_meta_data(https://stackoverflow.com/a/52684694) – however, I do not want to filter out the meta keys in the admin interface, but only on the generated invoices/package slips.Does the plugin offer some kind of conditional tag, similar to something like is_admin, is_product, etc. for checking whether the filter is being called from the plugin?
Btw it’s an awesome plugin!

For now I’m using the code:
add_filter('woocommerce_order_item_get_formatted_meta_data', function ($formatted_meta, $item) { if (is_wc_endpoint_url()) { return $formatted_meta; } foreach ($formatted_meta as $key => $meta){ if(in_array($meta->key, array('delivery_date', 'delivery_text', 'quantity_shipped'))) { unset($formatted_meta[$key]); } } return $formatted_meta; }, 10, 2);And this allows me to return the meta data to the API, which is what we need, and it is being filtered from invoices/packing slips, which is also we were looking for. However now I’m not able to see those fields in the admin interface, which is what we prefer.
