namespace Vendor\Module\Plugin\Checkout\CustomerData;
class Cart {
public function afterGetSectionData(\Magento\Checkout\CustomerData\Cart $subject, array $result)
{
$result['content'] = 'test'; // Add extra content here
return $result;
}
}
Create checkout_cart_sidebar_total_renderers.xml under Vendor\Module\view\frontend\layout
<?xml version="1.0"?>
<page xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:noNamespaceSchemaLocation="urn:magento:framework:View/Layout/etc/page_configuration.xsd">
<body>
<referenceBlock name="minicart">
<arguments>
<argument name="jsLayout" xsi:type="array">
<item name="components" xsi:type="array">
<item name="minicart_content" xsi:type="array">
<item name="children" xsi:type="array">
<item name="subtotal.container" xsi:type="array">
<item name="children" xsi:type="array">
<item name="extra" xsi:type="array">
<item name="component" xsi:type="string">uiComponent</item>
<item name="config" xsi:type="array">
<item name="template" xsi:type="string">Vendor_Module/checkout/minicart/content</item>
</item>
<item name="children" xsi:type="array">
<item name="subtotal.totals" xsi:type="array">
<item name="component" xsi:type="string">Magento_Checkout/js/view/checkout/minicart/subtotal/totals</item>
<item name="config" xsi:type="array">
<item name="template" xsi:type="string">Vendor_Module/checkout/minicart/content/data</item>
</item>
</item>
</item>
</item>
</item>
</item>
</item>
</item>
</item>
</argument>
</arguments>
</referenceBlock>
</body>
</page>
Create content.html under Vendor\Module\view\frontend\web\template\checkout\minicart
<div class="content">
<span class="label">
<!-- ko i18n: 'Extra Content' --><!-- /ko -->
</span>
<!-- ko foreach: elems -->
<!-- ko template: getTemplate() --><!-- /ko -->
<!-- /ko -->
</div>
Create data.html under Vendor/Module/view/frontend/web/template/checkout/minicart/content
<div>
<span class="label">
<!-- ko i18n: 'Extra content is ' --><!-- /ko -->
</span>
<span class="custom-wrapper" data-bind="html: cart().content_data"></span>
</div>
That’s it.
Just like showing additional data in mini cart you can also restrict quantity update from minicart in Magento 2 this will be helpful when you have set condition of limiting the order quantity.
