How do i override the submission url when i place order in magento. <p>so i have recently started using magento 1.9. and i have a specific problem i am not sure how to solve. I created a custom payment module, that shows up in the payment options, and when the user places the order , it redirects to my custom checkout success message. However this is not exactly what i want. I want to be able to redirect the user to my custom url if ANY payment option is selected, eg paypal or creditcard.</p> <p>In my custom controller, I want to append some info to the form, then forward it to the gateway. </p> <p>I guess the question is similar to this. But i dont want to edit magento's core code, I would like to override from my custom module. <a href="https://stackoverflow.com/questions/7749748/magento-place-order-redirection-for-payment-gateway">Magento &quot;place order&quot; redirection for payment gateway</a></p> <p>is there anyone that can help or point me in the right direction? </p>
