Ever had the requirement in your Magento 2 store of restricting a customer on purchase quantity? I\u2019m sure you had if you were concerned about cost-effective packaging, delivery, shipping, and stock management.<\/p>\n\n\n\n

Today, I\u2019ve come up with a method to restrict quantity update from mini cart in Magento 2<\/strong><\/em>. This is helpful when you have set a condition of limiting the order quantity. You can restrict customers to update the quantity in mini cart that violates the limit, and shows a message in the popup with the related restriction information.<\/p>\n\n\n\n

Method to Restrict Quantity Update From Mini Cart In Magento 2:<\/h2>\n\n\n\n

1. Create di.xml<\/strong> file at app\\code\\Vendor\\Extension\\etc\\frontend<\/strong><\/em><\/strong><\/em><\/p>\n\n\n\n

<?xml version=\"1.0\"?>\n<config xmlns:xsi=\"http:\/\/www.w3.org\/2001\/XMLSchema-instance\"\n        xsi:noNamespaceSchemaLocation=\"urn:magento:framework:ObjectManager\/etc\/config.xsd\">\n    <type name=\"Magento\\Checkout\\Controller\\Sidebar\\UpdateItemQty\">\n        <plugin name=\"quantity_update\" type=\"Vendor\\Extension\\Observer\\UpdateItemQty\" sortOrder=\"10\"\/>\n    <\/type>\n<\/config><\/pre>\n\n\n\n
2. Create UpdateItemQty.php<\/strong> file at app\\code\\Vendor\\Extension\\Observer<\/strong><\/em><\/strong><\/em><\/p>\n\n\n\n
<?php\n\nnamespace Vendor\\Extension\\Observer;\n\nuse Magento\\Checkout\\Controller\\Sidebar\\UpdateItemQty as coreUpdateItemQty;\nuse Vendor\\Extension\\Helper\\Data;\nuse Magento\\Framework\\Json\\Helper\\Data as coreData;\nuse Magento\\Checkout\\Model\\Sidebar;\nuse Magento\\Catalog\\Model\\ProductFactory;\nuse Magento\\Checkout\\Model\\Cart;\nuse Magento\\Framework\\Serialize\\SerializerInterface;\n\n\nclass UpdateItemQty\n{\n    protected $helper;\n    protected $jsonHelper;\n    protected $sidebar;\n    protected $quoteItemFactory;\n    protected $productFactory;\n    protected $cart;\n    protected $serializer;\n\n\n    public function __construct(\n        Data $helper,\n        coreData $jsonHelper,\n        Sidebar $sidebar,\n        Cart $cart,\n        SerializerInterface $serializer,\n        ProductFactory $productFactory\n    )\n    {\n        $this->helper = $helper;\n        $this->jsonHelper = $jsonHelper;\n        $this->sidebar = $sidebar;\n        $this->productFactory = $productFactory;\n        $this->serializer = $serializer;\n        $this->cart = $cart;\n    }\n\n    public function aroundExecute(coreUpdateItemQty $subject, \\Closure $proceed)\n    {\n\n        try {\n\n            if(your condition){\n                $errorMsg= 'Error Msg';\n                return $subject->getResponse()->representJson(\n                    $this->jsonHelper->jsonEncode($this->sidebar->getResponseData($errorMsg))\n                );\n            }\n        } catch (\\Exception $e) {\n            return $subject->getResponse()->representJson(\n                $this->jsonHelper->jsonEncode($this->sidebar->getResponseData($e->getMessage()))\n            );\n        }\n        return $proceed();\n\n    }\n}<\/pre>\n\n\n\n
That\u2019s it. You can also show additional data in Magento 2 mini cart<\/a> to show shipping charge, discount or tax information etc.<\/p>\n\n\n\n
Limit the quantity or set any conditions for updating quantity right in the mini cart with the above solution!<\/p>\n\n\n\n
