On my going Project a client requirement was adding custom shipping method so I was trying to solve the problem at last got a solution and it so i liked to share it hope it will be helpful for you.

In this article I will Discuss how to write custom shipping method in Magento commerce. First we need to write our shipping method, it’s a class in folder app/code/core/Mage/Shipping/Model/Carrier/.
I called it Inchoocustom.php and it’s based on Flat rate shipping method but you can developed your own class

getConfigFlag(‘active’)) {

return false;

}

$freeBoxes = 0;

if ($request->getAllItems()) {

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

if ($item->getFreeShipping() && !$item->getProduct()->isVirtual()) {

$freeBoxes+=$item->getQty();

}

}

}

$this->setFreeBoxes($freeBoxes);

$result = Mage::getModel(‘shipping/rate_result’);

if ($this->getConfigData(‘type’) == ‘O’) { // per order

$shippingPrice = $this->getConfigData(‘price’);

} elseif ($this->getConfigData(‘type’) == ‘I’) { // per item

$shippingPrice = ($request->getPackageQty() * $this->getConfigData(‘price’)) – ($this->getFreeBoxes() * $this->getConfigData(‘price’));

} else {

$shippingPrice = false;

}

$shippingPrice = $this->getFinalPriceWithHandlingFee($shippingPrice);

if ($shippingPrice !== false) {

$method = Mage::getModel(‘shipping/rate_result_method’);

$method->setCarrier(‘inchoocustom’);

$method->setCarrierTitle($this->getConfigData(‘title’));

$method->setMethod(‘inchoocustom’);

$method->setMethodTitle($this->getConfigData(‘name’));

if ($request->getFreeShipping() === true || $request->getPackageQty() == $this->getFreeBoxes()) {

$shippingPrice = ‘0.00’;

}

$method->setPrice($shippingPrice);

$method->setCost($shippingPrice);

$result->append($method);

}

return $result;

}

public function getAllowedMethods()

{

return array(‘inchoocustom’=>$this->getConfigData(‘name’));

}

}

?>

Pay attention on following lines:

$method->setCarrier(‘inchoocustom’);

$method->setCarrierTitle($this->getConfigData(‘title’));

$method->setMethod(‘inchoocustom’);

$method->setMethodTitle($this->getConfigData(‘name’));

They determine how we will set up our method. Keyword is ‘inchoocustom’. In folder app/code/core/Mage/Shipping/etc/ we need to edit

system.xml and config.xml in order to enable our new shipping method.

Now we need to enable our new shipping method in admin panel (System->Configuration->Shipping Methods) And we have our custom shipping method. Enjoy coding.
