Site Specific Plugin for Executing Code Snippet

I know a lot of us come across various code snippets while searching for a solution to a given problem pertaining to WordPress.
More often than not, you will be told to include the code snippet in your theme’s functions.php file.

This practice has its shortcoming – the code snippet disappears after a theme is updated.

Rather than adding code to theme’s functions.php, a site specific or custom functionality plugin is better.

All code hacks and snippets used by my WordPress blog are all in a dummy plugin named Hacks and Code.

Creating a dummy plugin

Follow the steps below to learn how dummy plugins are created taking my Hacks and Code plugin as an example.

1. In WordPress plugin folder (/wp-content/plugins), create a PHP file name my-hacks-code.php.
2. Add a plugin header as follows

   
   <?php
   /*
    Plugin Name: Hacks and Code
    Plugin URI: https://w3guy.com
    Description: WordPress code snippet den
    Author: Collizo4sky
    Author URI: https://w3guy.com/about/
    */
   

3. Dump the code snippet and save.
4. Go to your WordPress dashboard and activate the plugin.

When next you have a WordPress code snippet, dump it to the site specific plugin.
