Hi @shaar7
If you want to add a new field to the product upload form (popup/non-popup) then you can use the below-mentioned hook.
add_action( 'dokan_new_product_after_product_tags','your_custom_function',10 );
After that, you will need to use another hook that is mentioned below to save the data in order to edit and update it further.
add_action( 'dokan_new_product_added','function_to_save_product_meta', 10, 2 );
add_action( 'dokan_product_updated', 'function_to_save_product_meta', 10, 2 );
To show the data in the product edit page, use the hook mentioned below.
add_action('dokan_product_edit_after_product_tags','function_to_show_on_edit_page',20,2);
FInally, if you want to view the data in the single product page then you can use the below-mentioned hook.
add_action('woocommerce_single_product_summary','function_to_show_data',12);
As you are not interested in showing the data to the customer then you will not need to use the last hook.`
