module using header hook

[morp]

Hi all,
I need to create a module that identify when people are on products page. I think I have to use header hook, and then put in the page's code some javascript function (some google adword code).

Is there any Class to detect if customers are viewing a specific product pagea of a specific category?


many thanks

You can use this to get product id

        $id_product = intval(Tools::getValue('id_product'));
