eg. I am updated one feature in model app\code\Magefan\Blog\Model\Post.php How to add this update from my custom theme.

To achieve this you should override that class from your own module.

Create a Magento 2 module (lear here: https://devdocs.magento.com/videos/fundamentals/create-a-new-module/) and then add this in your etc/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">
    <preference for="Magefan\Blog\Model\Post" type="NameSpace\YourModule\Model\Magefan\Post" />

Now your class NameSpace\YourModule\Model\Magefan\Post.php


namespace NameSpace\YourModule\Model\Magefan;

class Post extends \Magefan\Blog\Model\Post {

    public function yourNewFunction()
        return true;

Now, if you call this function from your theme, then it should work.

  • To override you can create a new folder/file in your theme, app/design/frontend/Your_Theme/ThemeName/Magefan_Blog/templates/widget/recent.phtml. The idea is to place all the files inside Magefan_Blog with the same folder structure. And clear your cache. Mar 23, 2021 at 22:42
  • Model is rewrite using a custom module, for templates inside the theme folder, is it the correct way?

    Yes, that way, when that module is disabled, the theme will know and will not care about it. Mar 24, 2021 at 4:18
