There are two ways to get current product in Magento 2.

  1. Using custom block class extended from Magento\Catalog\Block\Product\AbstractProduct
  2. Using core registry.

Using custom block class:

In this method, we can extended our frontend block class i.e. Namespace/Modulename/Block/Myblock.php from Magento\Catalog\Block\Product\AbstractProduct which is a lightweight concrete class to get most product related information.

So, we can use the following code inside our custom module’s page configuration layout file which is Namespace/Modulename/view/frontend/layout/catalog_product_view.xml

<block class="Namespace\Modulename\Block\Product\View\Myblock" 
       name="product.info.myblock" 
       after="product.info.media.image" 
       template="Namespace_Modulename::product/view/myblock.phtml"/>

And now in our block class Namespace/Modulename/Block/Product/View/Myblock.php we need to something like:

<?php

namespace Namespace\Modulename\Block\Product\View;

class Myblock extends \Magento\Catalog\Block\Product\AbstractProduct
{
    public function __construct(\Magento\Catalog\Block\Product\Context $context, array $data = [])
    {
        parent::__construct($context, $data);
    }
}

As we extended our module’s block from Magento\Catalog\Block\Product\View we need to add Magento_Catalog as a dependency in our module.xml file

<?xml version="1.0"?>
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
        xsi:noNamespaceSchemaLocation="urn:magento:framework:Module/etc/module.xsd">
    <module name="Namespace_Modulename" setup_version="0.0.1">
        <sequence>
            <module name="Magento_Catalog"/>
        </sequence>
    </module>
</config>

And then in our block’s template file we can do something like

$this->product = $this->getProduct()->getId();

Using core registry:

This method is normally used where a ‘single’ product object is already loaded i .e. in any template files in product page. So, if we define a block in our module’s page configuration layout file which is Namespace/Modulename/view/frontend/layout/catalog_product_view.xml and set its block type class as

Magento\Catalog\Block\Product\View, we can then use the following code in block’s template file:

$this->product = $this->_coreRegistry->registry('product');
