How to Create/developed own WordPress plugin

Creating a complete CRUD (Create, Read, Update, Delete) plugin for WordPress involves several steps. Here’s a general outline of the process:
  1. Create a new plugin folder in the wp-content/plugins directory of your WordPress installation.
  2. Create a new PHP file in the plugin folder and add the plugin header information at the top of the file. This includes the plugin name, version, author, and description.
  3. Define the plugin activation and deactivation hooks to create and remove the necessary database tables for the CRUD operations.
  4. Define the shortcode function to display the CRUD interface on a WordPress page or post.
  5. Define the functions for each CRUD operation (create, read, update, delete) and add them to the shortcode function.
  6. Add the necessary HTML and CSS to create a user-friendly interface for the CRUD operations.
Here’s an example of what the code for a simple CRUD plugin might look like:
