According to the Magento Stack Exchange answer, form key validation is a security feature that prevents CSRF attacks by checking if the form key in the request matches the one generated by Magento. If the developer does not include the form_key in their custom form, the validation will fail and an error will be shown. Therefore, the developer needs to add the form_key to their requests by using <?= $block->getBlockHtml ('formkey') ?> in their template file. Verified

The following SearchCriteria query will replicate the SQL query:

$searchCriteria = new \Magento\Framework\Api\SearchCriteriaBuilder();

$searchCriteria->addFilter('name', 'Brand 1', 'eq');

$searchCriteria->addFilter('status', 1, 'eq');

$brandCollection = $this->brandRepository->getList($searchCriteria);

The plugin execution order is as follows:

PluginA::beforeDispatch()

PluginB::beforeDispatch()

PluginA::aroundDispatch()

The code in the around plugin

PluginB::afterDispatch()

PluginA::afterDispatch()

The aroundDispatch() method is executed in a separate scope, so the code in the around plugin will be executed after the beforeDispatch() methods of both plugins, but before the afterDispatch() methods of both plugins.

Here is a diagram that shows the plugin execution order:

PluginA

beforeDispatch()

aroundDispatch()

afterDispatch()

PluginB

beforeDispatch()

afterDispatch()

The extension attribute is referencing the repository instead of the interface it implements. The correct XML snippet should be:

XML

<extension_attributes>

group='General'

translate='true'>

<description>This attribute stores an array of custom values for the invoice.</description>

<source_model>Magento\Sales\Api\Data\InvoiceInterface</source_model>

</extension_attributes>

The source_model attribute specifies the interface that the extension attribute is associated with. In this case, the extension attribute is associated with the Magento\Sales\Api\Data\InvoiceInterface interface.

The developer can customize the appearance of the error message by calling the setDecorationType() method on the Symfony\Console\Output\OutputInterface object before calling writeln(). The setDecorationType() method takes a single argument, which is the type of decoration that the developer wants to use. In this case, the developer wants to use the STYPE_ERROR decoration, which will highlight the message in red.

Here is an example of how to customize the appearance of the error message:

$output = new Symfony\Console\Output\ConsoleOutput();

$output->setDecorationType(Symfony\Console\Output\OutputInterface::STYPE_ERROR);

$output->writeln('This is an error message.');

The output of this code will be an error message that is highlighted in red.

According to the Configure and run cron guide for Magento 2 developers, the crontab.xmi file is used to declare and configure cron jobs for a module. The file should specify the name, instance, method and schedule of the cron job. Therefore, creating a crontab.xmi file and setting a schedule for the new cron job are the minimally required steps to accomplish this task. Verified

If the Sodium extension is installed, Argon 2ID13 will be chosen as the Magento default hashing algorithm. Otherwise, SHA256 will be used.

The Sodium extension is a PHP extension that provides cryptographic functions. Argon 2ID13 is a password hashing algorithm that is considered to be more secure than SHA256.

If the Sodium extension is installed, Magento will use Argon 2ID13 as the default hashing algorithm for customer passwords. If the Sodium extension is not installed, Magento will use SHA256 as the default hashing algorithm.

The developer can achieve this by adding the following configuration to their di.xml file:

XML

<config>

<component name='Custom\Module\Model\Example' factory='Custom\Module\Model\ExampleFactory'>

</component>

</config>

This configuration will ensure that all instances of the Custom\Module\Model\Example class will receive a new instance of the Magento\Filesystem\Adapter\Local class.

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.
