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.

The developer can test the new feature under the integration environment by deactivating one of the active integration environment branches, creating a new active branch from integration and installing the module, and pushing the changes. This is because Enhanced Integration Environments have a limit of four active branches at a time, and each branch has its own dedicated database and services. The developer can use the Cloud CLI for Commerce tool to manage the branches and deploy the code changes.

To store a block in the system cache, the developer needs to set values for both the cache_lifetime and cache_key data properties of the block. The cache_lifetime property specifies how long the block should be cached, and the cache_key property specifies a unique identifier for the block.

The following code shows how to set the cache_lifetime and cache_key data properties of a block:

PHP

$block->setData('cache_lifetime', 600);

$block->setData('cache_key', 'my_custom_block');

Once the cache_lifetime and cache_key data properties have been set, the block will be stored in the system cache and will not be regenerated on each page load.

The developer can resolve this issue by creating a plugin for the Magento\Catalog\Model\Indexer\Product\Price::executeRow() method. This method is responsible for updating the product price index.

The plugin can be used to add the pricing adjustment from the database to the product price index. Once the product price index is updated, the layered navigation will display the correct price.

Here is an example of a plugin for the executeRow() method:

PHP

class MyPlugin

{

public function executeRow(

\Magento\Catalog\Model\Indexer\Product\Price $subject,

\Magento\Catalog\Model\Product $product,

array $data

) {

$adjustment = $this->getAdjustment($product);

$product->setPrice($product->getPrice() + $adjustment);

}

private function getAdjustment(Product $product)

{

$adjustment = $product->getData('adjustment');

if (!is_numeric($adjustment)) {

return 0;

}

return $adjustment;

}

}

This plugin will add the adjustment data from the product to the product price index. Once the product price index is updated, the layered navigation will display the correct price.

According to the ImageUploader component guide for Magento 2 developers, the ImageUploader UI component gives users the ability to upload images to the Magento Media Gallery. This component is a variation of the FileUploader component and uses the same configuration settings. The ImageUploader component uses the Magento\catalog\Model\iinageUploader class for image uploading, which has properties such as basePath and baseTmpPath that define where the images are stored. To extend the default imageuploader class and use it without affecting the other modules that are already using it, the developer needs to create a virtual type of this class in their module’s di.xml file and specify different values for basePath and baseTmpPath. The developer also needs to inject their virtual type into their admin controller using the imageUploader argument. Therefore, option B is the correct answer, as it shows the correct di.xml and controller code to extend and use the imageuploader class.

 The steps necessary prior to redeploying in order to upgrade to Enhanced Integration Environments are to limit the number of integration branches to two and to submit a support ticket requesting the upgrade. Enhanced Integration Environments are an improved version of integration environments that offer better performance, stability, and security. They have a limit of four active branches at a time, but only two branches can be migrated from standard integration environments. The developer needs to delete or deactivate any extra branches before requesting the upgrade from Adobe support. Verified References: [Magento 2.4 DevDocs]

The developer can set up a subdomain for one of their websites by configuring the subdomain route in the .magento/routes.yaml file. This file defines how incoming requests are routed to different applications or services on the Adobe Commerce Cloud platform. The developer needs to add a route for secondstore.example.com and map it to the same application as example.com. The developer also needs to specify the upstream variable for secondstore.example.com as MAGE_RUN_CODE and MAGE_RUN_TYPE.

The command used to upgrade ECE-Tools on an Adobe Commerce Cloud platform is composer update magento/ece-tools --with-all-dependencies. This command will update the ECE-Tools package and its dependencies to the latest version available in the composer repository. The developer then needs to commit and push the changes to the composer.json and composer.lock files and redeploy the environment. Verified References: [Magento 2.4 DevDocs]

The developer can create a snapshot before deploying a critical feature to their Adobe Commerce Cloud (Pro Plan) production by using the dedicated button on Project Web Interface. A snapshot is a backup of an entire environment, including code, data, media files, and configuration settings. A snapshot can be used to restore an environment to a previous state in case of any issues or errors during deployment or testing. The developer can create a snapshot by accessing the Project Web Interface, choosing an environment, and clicking Create Snapshot. Verified References: [Magento 2.4 DevDocs]

The input_type attribute of a product EAV attribute specifies the type of input field that will be used to enter the value of the attribute in the admin panel. The textarea input type is used for WYSIWYG fields. If the input_type attribute is not set to textarea, then the attribute will not appear as WYSIWYG in the admin panel.

To fix this, the developer should set the input_type attribute to textarea.

The developer has to add a formkey for the new export option because the formkey is required for security reasons. Without the formkey, the request will be rejected and redirected to the dashboard page. Verified References: [Magento 2.4 User Guide] [Magento 2.4 DevDocs]
