Custom Shipping Method - Please specify a shipping method - php

Question

I'm working on a custom shipping method and I've been getting exception each times I try to place an order with my method ("Please specify a shipping method").
I tried with the Magento 2 Flat Rate method and it worked.
I found that in Magento/Quote/Model/QuoteValidator.php on line 52, the getShippingMethod() returned nothing because that function :
public function getShippingMethod()
{
return $this->getData('shipping_method');
}
in Magento/Quote/Model/Quote/Address.php returned nothing.
Just in case my code was wrong, I also tried with this custom shipping method (I followed this tutorial to create the method) http://www.blog.magepsycho.com/create-custom-shipping-module-in-magento-2/ (just activate the module and tried to place an order with that method) but I'm facing the same issue.
Does someone know how I can resolve this issue ?
Thanks.
Here is my Model/Carrier/method.php :
class Method extends \Magento\Shipping\Model\Carrier\AbstractCarrier implements \Magento\Shipping\Model\Carrier\CarrierInterface
{
protected $_logger;
/**
* #var string
*/
protected $_code = 'coursierprive_transport';
/**
* #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;
$this->_logger = $logger;
parent::__construct($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);
if ($request->getAllItems())
{
foreach ($request->getAllItems() as $item)
{
// Some stuff used to check dimensions, weight, post code... etc
}
}
if (//some tests)
return (false);
$result = $this->_rateResultFactory->create();
$shippingPrice = 5.5;
$method = $this->_rateMethodFactory->create();
$method->setCarrier($this->_code);
$method->setCarrierTitle($this->getConfigData('title'));
$method->setMethod($this->_code);
$method->setMethodTitle($this->getConfigData('name'));
if ($request->getFreeShipping() === true || $request->getPackageQty() == $this->getFreeBoxes())
$shippingPrice = 0;
$method->setPrice($shippingPrice);
$method->setCost($shippingPrice);
$result->append($method);
return ($result);
}
/**
* Get allowed shipping methods
*
* #return array
*/
public function getAllowedMethods()
{
return (['coursierprive_transport' => $this->getConfigData('name')]);
}
}
Here is my Config.xml :
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="../../../Magento/Store/etc/config.xsd">
<default>
<carriers>
<coursierprive_transport>
<active>1</active>
<sallowspecific>0</sallowspecific>
<price>5.5</price>
<model>CoursierPrive\Transport\Model\Carrier\Method</model>
<name>Express</name>
<title>Coursier Privé</title>
<specificerrmsg>This shipping method is not available. To use this shipping method, please contact us.</specificerrmsg>
</coursierprive_transport>
</carriers>
</default>
</config>
I think that I know what messed up. I suppose there is a size limit for the method name and my first name contained too many chars.

Answer 1

Try to change the code to something short like:
protected $_code = 'couriertransport';
I am not sure if this is the issue but doing so fixed the issue:

Answer 2

My case : protected $_code = 'effectconnect_shipment';
=> so full code must be 'effectconnect_shipment_effectconnect_shipment'
I checked the length of this code is only 40 so rename it to $_code = 'effectconnect'; and it work !!!
