In this article we will address the issue that is widely discussed at the Magento 2 thematic forums — when you add a product to the user’s cart programmatically, the cost of the product becomes zero. To solve this problem, we have created a module that provides a convenient interface for adding items to the selected basket.
Install the test instance Magento 2.3.0 with sample data.

composer create-project --repository=https://repo.magento.com/ "magento/project-community-edition":"2.3.0" /var/www/magento-2.3.0.test php bin/magento setup:install --base-url="http://magento-2.3.0.test/" --db-host="mysql" --db-name="magento_2_3_0" --db-user="root" --db-password="root" --admin-firstname="admin" --admin-lastname="admin" --admin-email="[email protected]" --admin-user="admin" --admin-password="Admin123" --language="en_US" --currency="USD" --use-rewrites="1" --backend-frontname="backadmin" --timezone="UTC" php bin/magento sampledata:deploy php bin/magento setup:upgrade php bin/magento indexer:reindex |
At the end of the article you will find the code of the developed module. The module creates a page in the Magento administration panel with an interface for adding items to the cart with an indication of the SKU (if necessary) and quantity. The action to add goods to the basket is performed in the action Index. Bear in mind there still can be difficulties with the use of different types of goods (Simple, Virtual, Configurable, Downloadable, Bundle, Grouped), because for certain the parameter of the addProduct function of the Quote object should be formed in a special way.

Visit the pageHaving tested all variations of types of goods, we found no problems with the price. Therefore, we conclude that this problem is not connected with the standard delivery of Magento 2.3.0, but rather lies in mistakes in the code or a conflict with a third-party module. Ideally, each case when a problem with the price during the programmatic addition of goods to the basket is individual and must be considered separately to determine and eliminate an underlying cause.
