How I can Force that isset to do what he must do

I tried to insert it everywhere in the code, before calling from the database, after, at the beginning, at the end... And the worst thing is when I include the wishlist_cart.php and when I press add_to_cart I get a message that it has been added to the basket, but the basket remains empty.

Isset 'add_to_cart' didnt work on only one page
