The shipping method would display $10 and customers would pay $10 for using the new shipping method. This is because the collectRates method sets the price and cost of the shipping method to 10 in the result object. The price is what is shown to the customer on the frontend and the cost is what is charged to the customer when they place the order. The handling fee is not used in this case because it is set to zero in the config.xml file. Verified References: [Magento 2.4 DevDocs] [Magento Stack Exchange]

The developer can add a custom filter to the virtual type Magento\Catalog\Model\Api\SearchCriteria\CollectionProcessor\ProductFilterProce5sor for supplier_id field. In the custom filter, the developer can apply the needed join and filter to the passed $collection. This is the recommended way to extend the search criteria for products using dependency injection and plugins. Verified References: [Magento 2.4 DevDocs] [Magento Stack Exchange]

Two options to get the connection credentials for the environment’s deployed services are to run the magento-cloud relationships CLI command and to connect to the server via SSH and read $_ENV[‘services’] variable. The magento-cloud relationships CLI command displays information about the relationships between an environment and its services, such as database, cache, search, etc. The developer can use this command to get the connection data for each service in JSON format. Alternatively, the developer can connect to the server via SSH and read the $_ENV[‘services’] variable, which contains the same information as the CLI command output.

To display the "file upload" field and process the actual CSV import, the following two requirements must be met:

The developer must create a new system configuration setting that specifies the path to the CSV file.

The developer must create a new controller action that handles the file upload and import process.

The system.xml file is used to define system configuration settings. The following XML snippet shows how to define a new system configuration setting for the CSV file path:

XML

/path/to/csv/file

The Controller\Adminhtml\ShipmentFees controller class is used to handle the file upload and import process. The following code shows how to create a new controller action that handles the file upload and import process:

PHP

public function uploadAction()

{

$file = $this->getRequest()->getFile('shipment_fees_csv_file');

if ($file->isUploaded()) {

$importer = new ShipmentFeesImporter();

$importer->import($file);

}

return $this->redirect('adminhtml/system_config/edit/section/shipment_fees');

}

The developer should create an extension attribute on the Magento\Sales\Api\Data\OrderInterface interface and an after plugin on the Magento\Sales\Api\OrderRepositoryInterface::get() and Magento\Sales\Api\OrderRepositoryInterface::getList() methods.

The extension attribute will store the custom data. The after plugin will be used to add the custom data to the order object when it is fetched from the API.

Here is the code for the extension attribute and after plugin:

PHP

namespace MyVendor\MyModule\Api\Data;

interface OrderExtensionInterface extends \Magento\Sales\Api\Data\OrderInterface

{

/**

* Get custom data.

*

* @return string|null

*/

public function getCustomData();

/**

* Set custom data.

*

* @param string $customData

* @return $this

*/

public function setCustomData($customData);

}

namespace MyVendor\MyModule\Model;

class OrderRepository extends \Magento\Sales\Api\OrderRepositoryInterface

{

/**

* After get order.

*

* @param \Magento\Sales\Api\OrderRepositoryInterface $subject

* @param \Magento\Sales\Api\Data\OrderInterface $order

* @return \Magento\Sales\Api\Data\OrderInterface

*/

public function afterGetOrder($subject, $order)

{

if ($order instanceof OrderExtensionInterface) {

$order->setCustomData('This is custom data');

}

return $order;

}

/**

* After get list.

*

* @param \Magento\Sales\Api\OrderRepositoryInterface $subject

* @param \Magento\Sales\Api\Data\OrderInterface[] $orders

* @return \Magento\Sales\Api\Data\OrderInterface[]

*/

public function afterGetList($subject, $orders)

{

foreach ($orders as $order) {

if ($order instanceof OrderExtensionInterface) {

$order->setCustomData('This is custom data');

}

}

return $orders;

}

}

Once the extension attribute and after plugin are created, the custom data will be added to orders fetched from the API.
