Create Custom Shipping Module in Magento 2

November 25, 2015  |  10 Comments  |  by Raj (MagePsycho)  |  Magento 2

As you know Magento 2 GA is already released on mid of November, 2015. Now the development of Magento 2 components is taking by storm and the developers are especially busy with porting their popular Magento 1 extensions.

In ours case, We are already into Magento 2 development: busy porting some of our popular Magento 1 Extensions and side by side learning new concepts introduced by Magento 2.

In this tutorial we will learn how to create a custom shipping module in Magento2 which is fairly easy as compared to CRUD & Payment modules.

Assumptions:
Namespace = MagePsycho
Module = Customshipping

Custom Shipping Module Development

1. Register the module
File: app/code/MagePsycho/Customshipping/etc/module.xml

<?xml version="1.0"?>
<!--

<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="../../../../../lib/internal/Magento/Framework/Module/etc/module.xsd">
    <module name="MagePsycho_Customshipping" setup_version="1.0.0">
    </module>
</config>

2. Add System Configuration Settings
File: app/code/MagePsycho/Customshipping/etc/adminhtml/system.xml

<?xml version="1.0"?>

        </section>
    </system>
</config>

3. Define shipping carrier model
File: app/code/MagePsycho/Customshipping/etc/config.xml

<?xml version="1.0"?>
<!--
/**
 * @category   MagePsycho
 * @package    MagePsycho_Customshipping
 * @author     magepsycho@gmail.com
 * @website    http://www.magepsycho.com
 * @license    http://opensource.org/licenses/osl-3.0.php  Open Software License (OSL 3.0)
 */
-->
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="../../../Magento/Store/etc/config.xsd">
    <default>
        <carriers>
            <magepsycho_customshipping>
                <active>0</active>
                <sallowspecific>0</sallowspecific>
                <price>0</price>
                <model>MagePsycho\Customshipping\Model\Carrier\Customshipping</model>
                <name>Fixed</name>
                <title>Custom Shipping</title>
                <specificerrmsg>This shipping method is not available. To use this shipping method, please contact us.</specificerrmsg>
            </magepsycho_customshipping>
        </carriers>
    </default>
</config>

Notes: ‘config/default/carriers/model’ node is used to define Model class for Custom Shipping which will be responsible for handling the Shipping Charges.
In fact this file is also used to set default values for Shipping Settings.

4. Create shipping carrier model class
File: app/code/MagePsycho/Customshipping/Model/Carrier/Customshipping.php

<?php

namespace MagePsycho\Customshipping\Model\Carrier;

use Magento\Quote\Model\Quote\Address\RateRequest;

/**
 * @category   MagePsycho
 * @package    MagePsycho_Customshipping
 * @author     magepsycho@gmail.com
 * @website    http://www.magepsycho.com
 * @license    http://opensource.org/licenses/osl-3.0.php  Open Software License (OSL 3.0)
 */
class Customshipping extends \Magento\Shipping\Model\Carrier\AbstractCarrier implements
	\Magento\Shipping\Model\Carrier\CarrierInterface
{
	/**
	 * @var string
	 */
	protected $_code = 'magepsycho_customshipping';

	/**
	 * @var bool
	 */
	protected $_isFixed = true;

	/**
	 * @var \Magento\Shipping\Model\Rate\ResultFactory
	 */
	protected $_rateResultFactory;

	/**
	 * @var \Magento\Quote\Model\Quote\Address\RateResult\MethodFactory
	 */
	protected $_rateMethodFactory;

	/**
	 * @param \Magento\Framework\App\Config\ScopeConfigInterface $scopeConfig
	 * @param \Magento\Quote\Model\Quote\Address\RateResult\ErrorFactory $rateErrorFactory
	 * @param \Psr\Log\LoggerInterface $logger
	 * @param \Magento\Shipping\Model\Rate\ResultFactory $rateResultFactory
	 * @param \Magento\Quote\Model\Quote\Address\RateResult\MethodFactory $rateMethodFactory
	 * @param array $data
	 */
	public function __construct(
		\Magento\Framework\App\Config\ScopeConfigInterface $scopeConfig,
		\Magento\Quote\Model\Quote\Address\RateResult\ErrorFactory $rateErrorFactory,
		\Psr\Log\LoggerInterface $logger,
		\Magento\Shipping\Model\Rate\ResultFactory $rateResultFactory,
		\Magento\Quote\Model\Quote\Address\RateResult\MethodFactory $rateMethodFactory,
		array $data = []
	) {
		$this->_rateResultFactory = $rateResultFactory;
		$this->_rateMethodFactory = $rateMethodFactory;
		parent::__construct($scopeConfig, $rateErrorFactory, $logger, $data);
	}

	/**
	 * @param RateRequest $request
	 * @return \Magento\Shipping\Model\Rate\Result
	 * @SuppressWarnings(PHPMD.UnusedLocalVariable)
	 */
	public function collectRates(RateRequest $request)
	{
		if (!$this->getConfigFlag('active')) {
			return false;
		}

		/** @var \Magento\Shipping\Model\Rate\Result $result */
		$result = $this->_rateResultFactory->create();

		$shippingPrice = $this->getConfigData('price');

		$method = $this->_rateMethodFactory->create();

		$method->setCarrier($this->_code);
		$method->setCarrierTitle($this->getConfigData('title'));

		$method->setMethod($this->_code);
		$method->setMethodTitle($this->getConfigData('name'));

		$method->setPrice($shippingPrice);
		$method->setCost($shippingPrice);
		
		$result->append($method);

		return $result;
	}

	/**
	 * Get allowed shipping methods
	 *
	 * @return array
	 */
	public function getAllowedMethods()
	{
		return [$this->_code => $this->getConfigData('name')];
	}
}

That’s all from development point of view.
Now you need to enable the module by running following series of commands(from root of your Magento 2 installation):

php bin/magento module:enable MagePsycho_Customshipping --clear-static-content
php bin/magento setup:upgrade

Go to the backend: System > Configuration > Sales > Shipping Methods > You will see new tab named ‘Custom Shipping’. And the settings looks like:

Magento 2 - Custom Shipping Method

Magento 2 – Custom Shipping Method

And the frontend looks like:

Magento2  - Custom Shipping at Checkout

Magento2 – Custom Shipping – Checkout

Magento2 - Custom Shipping - Checkout Summary

Magento2 – Custom Shipping – Checkout Summary

This module is available on GitHub.
In order to install the module from github:
Installation Using Composer

composer config repositories.magesycho-magento2-custom-shipping git git@github.com:MagePsycho/magento2-custom-shipping.git
composer require magepsycho/magento2-custom-shipping:dev-master

Installation Using Zip
Download the zip file, extract & upload the files to path: app/code/MagePsycho/Customshipping/

After installation, don’t forget to enable the Module as described above.

Happy Magento 2 Coding!

Change shipping price & handling fee on the fly in Magento

October 10, 2013  |  3 Comments  |  by Raj (MagePsycho)  |  Magento

Problem: How do I change shipping prices and handling fees on the fly?

You may want to have different shipping prices for different scenarios. Your scenario could be any of the following:

  1. 1. Different shipping price based on shipping address
  2. 2. Different shipping price based on weight
  3. 3. Different shipping price based on categories
  4. 4. Different shipping price based on no of items
  5. 5. Different shipping price based on your custom module
  6. 6. Different shipping price based on some conditions

There may be many solutions. A flexible solution which works for most cases is to develop a custom module which implements the event called ‘sales_quote_collect_totals_before’

Solution:

Assuming the skeleton module: MagePsycho_Shipmentfilter has already been created.
1. Register the event ‘sales_quote_collect_totals_before’:
Add the following xml code in app/code/local/MagePsycho/Shipmentfilter/etc/config.xml

...
<events>
    <sales_quote_collect_totals_before>
        <observers>
            <your_module>
                <type>singleton</type>
                <class>shipmentfilter/observer</class>
                <method>salesQuoteCollectTotalsBefore</method>
            </your_module>
        </observers>
    </sales_quote_collect_totals_before>
</events>
...

2. Implement the observer model:
Create the observer file: app/code/local/MagePsycho/Shipmentfilter/Model/Observer.php and add the following code:

class MagePsycho_Shipmentfilter_Model_Observer
{
    public function salesQuoteCollectTotalsBefore(Varien_Event_Observer $observer)
    {
        /** @var Mage_Sales_Model_Quote $quote */
        $quote = $observer->getQuote();
        $someConditions = true; //this can be any condition based on your requirements
        $newHandlingFee = 15;
        $store    = Mage::app()->getStore($quote->getStoreId());
        $carriers = Mage::getStoreConfig('carriers', $store);
        foreach ($carriers as $carrierCode => $carrierConfig) {
            if($carrierCode == 'fedex'){
                if($someConditions){
                    Mage::log('Handling Fee(Before):' . $store->getConfig("carriers/{$carrierCode}/handling_fee"), null, 'shipping-price.log');
                    $store->setConfig("carriers/{$carrierCode}/handling_type", 'F'); #F - Fixed, P - Percentage                  
                    $store->setConfig("carriers/{$carrierCode}/handling_fee", $newHandlingFee);
    
                    ###If you want to set the price instead of handling fee you can simply use as:
                    #$store->setConfig("carriers/{$carrierCode}/price", $newPrice);
    
                    Mage::log('Handling Fee(After):' . $store->getConfig("carriers/{$carrierCode}/handling_fee"), null, 'shipping-price.log');
                }
            }
        }
    }
}

Notes: Here we are adding handling fee of 15 for Fedex shipping carrier on some conditions.
If you want to set a new price instead of a handling fee then you can simply use:

$store->setConfig("carriers/{$carrierCode}/price", $newPrice);

in above code.
Similarly you can add any custom shipping price for any other shipping method.

3. Bingo!
