 * Hello,
 * I’m using add_action( ‘woocommerce_product_data_panels’, ” ); to modify some 
   product metas while updating it.
    I wrote some code using the set_attributes()
   methode from WC_Product classes, but after saving the product using the save()
   methode, nothing appears in the Attributes pannel,
 * Can you help me please ?
 * Regards

 * Hi there,
 * Here is an approach that uses `wp_ajax_woocommerce_save_attributes`
    [https://stackoverflow.com/questions/52283313/how-can-i-save-a-custom-field-of-an-attribute-in-woocommerce](https://stackoverflow.com/questions/52283313/how-can-i-save-a-custom-field-of-an-attribute-in-woocommerce)–
   maybe you can use this as a starting point.

 * Hello,
 * I’ll just give up… I’m tiered of working on that.
 * mikejolley tells on github that ‘Using wp_ajax hooks is not ideal.’ [https://github.com/woocommerce/woocommerce/issues/16934](https://github.com/woocommerce/woocommerce/issues/16934)
   
   The exemple use neither the “_product_attributes” variable, or the “WC_product-
   >set_attributes()” methode. And I don’t understand why. Even if I update “_product_attributes”
   variable, it is not a unique field and will only result on an other stack impossible
   to get.
 * What I don’t understand is what blocking me from setting the attributes with 
   the dedicated methode of the class… I can do anything else like setting tags 
   and categories, but set_attributes always result in nothing.
 * Thanks,
