I implemented magento as an internal webshop of an organization. The shipping, billing and payment informations are same for all orders (and they will be automatically filled in by LDAP). Thus, I want to skip the first 4 checkout steps and to land on order "review".
I've already looked at the classes:
Controller/Checkout/controllers/OnepageController.php
Model/Checkout/Model/Type/Onepage.php
But I couldn't find, which Method is triggered by the button proceed the checkout.
How can I realize it?
