Magento: Remove JavaScript from checkout page
I'm currently creating a checkout page in Magento based on "One Page Checkout" - or well, I emptied onepage.phtml and started from scratch.

The order gets placed and everything, but the user is never coming to the third-party payment page; some payment methods return a blank page while other returns the error code *"Error in Klarna::setConfig: Missing config field(s): secret"*.

I suspect that some missing JavaScript is involved, so my final question is: **Is it possible to make the checkout work without JavaScript and, in that case, how?**

If relevant, here is the PHP code I use to create the order (placed in the top of onepage.phtml).

    <?php
    	$checkout = Mage::getSingleton('checkout/type_onepage');
    	
    	//STEP(1)
    	$checkout->saveCheckoutMethod('guest');
    	
    	//STEP(2)
    	$checkout->saveBilling($_POST['billing'], false);
    	
    	//STEP(3)
    	$checkout->saveShipping($_POST, false);
    	
    	//STEP(4)
    	$checkout->saveShippingMethod('flatrate_flatrate');
    	
    	//STEP(5)
    	$checkout->savePayment($_POST['payment']);
    	
    	//STEP(6)
    	$checkout->saveOrder();
    ?>

Thank you in advance!
