Magento 2 – Easy way to find block class name in phtml

Method 1: Using PHP within PHTML

The easiest way to find the block class name directly within a PHTML file is to use a small snippet of PHP code. Add the following code to your PHTML file:

<?php
echo get_class($block);
?>

This code will output the class name of the block that is rendering the template.

Method 2: Using Layout XML Files

Another approach is to inspect the layout XML files, which define the relationship between blocks and templates. Here’s how you can do it:

1. Navigate to the relevant layout XML file, usually found in app/code/<Vendor>/<Module>/view/frontend/layout or app/design/frontend/<Vendor>/<Theme>/Magento_<Module>/layout.
2. Search for the block tag that references your PHTML file using the template attribute.
3. Identify the class name specified in the class attribute of the block tag.
