Can you detail a little? Where exactly do you want to call, directly in the controller? Through a module in a certain hook?

I'm trying writing a module, for my website to synchronize quantities through in a webservice in hook of the product page, everything works for me, except in case the product has combinations.
I need to check the product id of the current combination and update the quantities via the reference.

 $product = new 
         
               Product(Tools::getValue('id_product'));
               $idarticolo = $product->reference;               

            if ($product->hasAttributes()) {

                        $id_product_attribute=Tools::getValue('id_product_attribute');
                         $combination = new Combination($id_product_attribute);                        
                        $idarticolo = $combination->reference;

            }
     

can you help me?

can someone help me? I can't get the id of the current combination in any way

[Ress]

Can you also show in which function you wrote that code? In a specific hook?

[pavel83]

for products without combinations, there are no problems, for those with combinations I can't query find the current id combination of the active product so it doesn't work for me

i am trying this

     $id_product_attribute=Tools::getValue('id_product_attribute');

but doens't work
