i'am new at cs.cart and develop for an addon for german "age-verification" (AltersprÃ¼fung / Schufa Premium) for my ezigarettes-customer.
My addon now is working, but i wan't to make it perfect. In mein checkout.pre.php controller i have the follow code, if the verification is negative:
return array(CONTROLLER_STATUS_REDIRECT, 'checkout.checkout');
Now i wan't redirect to the checkout. How i can redirect to the checkout and open step2, so that is open? I need it because the customer must check his biling-data,
