Make custom shipping method available in admin order

Question

I have built a shipping module that calculates a number of things, then makes three options available for the customer to choose from. I am not using any of the built-in options for shipping.

When I try to create an order (from scratch or a reorder) from the admin, it gives me the message Sorry, no quotes are available for this order at this time.

How do I make my shipping method available to the admin? Do I have to create a separate module for the admin or is there xml I can add to make this available?

I am running version 1.9.

For the cart functions, I won't paste them all here, but some of the items in question have to do with getting the customer's cart. Do these things work for the admin?

$count = Mage::getSingleton('checkout/session')->getQuote()->getItemsSummaryQty();
$cart = Mage::getSingleton('checkout/cart');

This is how the functions are being initialized:

class ECB_Shipping_Model_Carrier
    extends Mage_Shipping_Model_Carrier_Abstract
        implements Mage_Shipping_Model_Carrier_Interface {

The easiest method, the better. If this isn't possible and there is a way to just override this completely and have the admin enter the shipping, that's a fine end solution.

Answer 1

No need create separate module for the admin or is there xml.

Your bellow code is not working both end (frontend & admin)

$count = Mage::getSingleton('checkout/session')->getQuote()->getItemsSummaryQty();
$cart = Mage::getSingleton('checkout/cart');

So please use bellow code in model file ECB_Shipping_Model_Carrier and it is no issue both end (admin & frontend) and shipping method also available to admin

<?php

class ECB_Shipping_Model_Carrier
    extends Mage_Shipping_Model_Carrier_Abstract
    implements Mage_Shipping_Model_Carrier_Interface

{

   ...
   ...
   ...
    public function collectRates(Mage_Shipping_Model_Rate_Request $request)
    {
        if (!$this->getConfigFlag('active')) {
            return false;
        }

        $freeBoxes = 0;
        $count = count($request->getAllItems());

        if ($request->getAllItems()) {
            foreach ($request->getAllItems() as $item) {

                if ($item->getProduct()->isVirtual() || $item->getParentItem()) {
                    continue;
                }

                if ($item->getHasChildren() && $item->isShipSeparately()) {
                    foreach ($item->getChildren() as $child) {
                        if ($child->getFreeShipping() && !$child->getProduct()->isVirtual()) {
                            $freeBoxes += $item->getQty() * $child->getQty();
                        }
                    }
                } elseif ($item->getFreeShipping()) {
                    $freeBoxes += $item->getQty();
                }
            }
        }

        ...
        ...
        ...

        return $result;
    }
    ...
    ...
    ...
}
?>
