php - Magento Save Order function where it is? -

i'm checking since hours magento files. i'm in checkout onepage /checkout/onepage/reviews/info.phtml, order saved phone call ajax,

<script type="text/javascript"> //<![cdata[ review = new review('<?php echo $this->geturl('checkout/onepage/saveorder', array('form_key' => mage::getsingleton('core/session')->getformkey())) ?>', '<?php echo $this->geturl('checkout/onepage/success') ?>', $('checkout-agreements')); //]]> </script>

i'm new syntax, there no saveorder file in onepage template folder, need hack saveorder action alter redirect succes page payment gateway , come back. method is? don't understand phone call ajax new object instance.

any help appreciated.

so checkout/onepage/saveorder route corresponds module/controller/action. map to:

install_path/app/code/core/mage/checkout/controllers/onepagecontroller.php

and method looking saveorder.

that said should not ever go hacking core files. can observer or class rewrite override functionality.
