Germanized compatibility PHP error

Hi there,

I’m the plugin author of Germanized for WooCommerce. Seems like you are providing a custom integration for Germanized within controllers/products-manager/wcfm-controller-integrations-product-manage.php which uses custom logic to store meta data for Germanized via wcfm_woocommerce_germanized_product_meta_save. Could you please use defensive programming and check for function existence to prevent fatal errors? Germanized does not provide wc_ts_set_crud_data as a function.

Anyway it would be more suitable to call WC_Germanized_Meta_Box_Product_Data::instance()->save_product_data() instead of copying the whole logic. See https://github.com/vendidero/woocommerce-germanized/blob/master/includes/admin/meta-boxes/class-wc-germanized-meta-box-product-data.php#L1046 for details.

Cheers
