Hello Dolly Extended

An exercise to demonstrate the power of php classes to new WordPress developers

These plugins have been written to help new WordPress plugin developers understand the power of writing WordPress plugins using php classes. Due to the rapid rate and growth of WordPress as a content management system, there are an overwhelming number of blog posts that teach WordPress plugin developers to code their plugins purely in php functions which are not contained within a php class.

This method may seem fine to new developers as their plugins will work however this method doesn't allow other WordPress developers to 'modify' or 'tweak' the original plugin to suit their own needs.

This repository will be an code resource for an article written for Code Poet.

#Installation Notes

  1. Deactivate the existing Hello Dolly version that ships with WordPress (currently version 1.6)
  2. Upload oh-hello.php and the entire hello-extended folder to your WordPress plugins folder. This is usually wp-content\plugins unless you have a modified install.
  3. Activate Hello Dolly Version 1.7
  4. Activate Hello Dolly Extended
