I want to customize my minicart in Magento 2. I need to add 3 attributes

Question

I want to customize my minicart in Magento 2. I need to add 3 attributes: SKU, Manufacturer, and Manufacturer part number. These are existing attributes. I see where to add the output values but not where to call them from.

You can create a module to do this. It will use a plugin to add the attributes to the data array which is read by the knockout js template. Then we need to override the template to display these values.

This is the module directory:

|   registration.php
|   
+---etc
|   |   module.xml
|   |   catalog_attributes.xml
|   |   
|   \---frontend
|           di.xml
|           
+---Plugin
|       DefaultItem.php
|       
\---view
    +---frontend
    |   \---layout
    |           checkout_cart_sidebar_item_renderers.xml
    |           
    \---web
        \---template
            \---mini cart
                \---item
                        default.html

catalog_attributes.xml

<?xml version="1.0"?>

<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:module:Magento_Catalog:etc/catalog_attributes.xsd">
    <group name="quote_item">
        <attribute name="manufacturer"/>
        <attribute name="part_number"/>
    </group>
</config>

di.xml

<?xml version="1.0"?>

<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
        xsi:noNamespaceSchemaLocation="urn:magento:framework:ObjectManager/etc/config.xsd">
    <type name="Magento\Checkout\CustomerData\DefaultItem">
        <plugin name="AddAttPlug" type="Your\Module\Plugin\DefaultItem" disabled="false" sortOrder="10"/>
    </type>
</config>

DefaultItem.php

<?php

namespace Your\Module\Plugin;

use Magento\Quote\Model\Quote\Item;

class DefaultItem
{
    public function aroundGetItemData($subject, \Closure $proceed, Item $item)
    {
        $data = $proceed($item);
        $product = $item->getProduct();

        $atts = [
            "product_manufacturer" => $product->getAttributeText('manufacturer'),
            "product_part_number" => $product->getAttributeText('product_part_number')
        ];

        return array_merge($data, $atts);
    }
}

SKU already exists in data so no need to add it.

I added this and now my output states "UNDEFINED." Does that mean its working but I have my attributes are misnamed? — Matthew McLennan, Commented Sep 2, 2016 at 13:33
Registration.php and module.xml are boilerplate files, you should check out this tutorial alanstorm.com/magento_2_mvvm_mvc to get a handle on how m2 modules are defined. Could you maybe post a screenshot of the error your getting or else be more specific? — Aaron Allen, Commented Sep 2, 2016 at 20:08
@AaronAllen, Its work for me, but I also want to override the content.html of the same minicart and want to add some dynamic data in that file. Can you please explain how I can achieve this. Thanks in advance ! — Ashish Jagnani, Commented Sep 5, 2016 at 13:32
Instead if loading the attributes in aroundGetItemData() it is possible to add them to etc/catalog_attributes.xml. Having done that the attributes can be accessed with $item->getProduct()->getAttributeText('attribute_code'); _productRepo is no longer needed. — Andreas Riedmüller, Commented Sep 28, 2017 at 11:49

i have slove my query by 2 simple step in magento 2.1:

Change into file :->

1.DefaultItem.php Add line :

    $objectManager = \Magento\Framework\App\ObjectManager::getInstance();
    $this->product = $objectManager->get('Magento\Catalog\Model\Product')-
    >load($this->item->getId());

   *Add element into return array result:*

   'short_description' => $this->product->getShortDescription(),

2.default.html Add line:

   <a data-bind="text: short_description"></a>

i hope this will help you.
