I understand I can copy this file to my theme and override it without making xml updates. I just can't get the folder right where it should live.

I think you misunderstood about Namespace_Module.

You need to get this value in the module’s registration.php file.

For example, an extension is located in <magento dir>/vendor/magetu/checkout-module. You need to get the value Namespace_Module in <magento dir>/vendor/magetu/checkout-module/registration.php


use \Magento\Framework\Component\ComponentRegistrar;

ComponentRegistrar::register(ComponentRegistrar::MODULE, 'Magetu_Checkout', __DIR__);

Your phtml override file should be located in <theme_dir>/Magetu_Checkout/templates/file.phtml

    You are correct Tu. using the correct details from the registration file kicked it into action straight away. Thank you very much for your help

The full path should be: app/design/frontend/<Vendor>/<theme>/<Namespace>_<Module>/templates/file.phtml

HTH, Tom

  • Thanks for taking the time to reply Tom, this is actually where I put the files, just me shortening the theme folder name
