A) Installation instructions – top

Just copy this plugin (the entire ‘email-registered-users’ folder) into your WordPress plugins directory. Then go to your plugin section in the WordPress CMS and click ‘Activate’.

B) Short Description – top

This plugin collects all email addresses of the registered users of your WordPress website and groups them according to user role.

You can then email all users per user role, per email address or just all at once through your own email program by clicking the appropriate links.

C) PHP File functions and Structure – top

Functions

The plugin consists of one simple PHP file (‘cc-index.php’) which contains all the necessary PHP functions and includes for this plugin. These are the functions briefly explained;

	/* === Plugin functions === */

	eru_add_page();
	adds WordPress options page under the Tools tab

	eru_options_page();
	builds the options page

	eru_admin_head();
	loads the eru-style.css file

	get_email_info();
	this is where the actual work happens. Collects all
        email addresses, puts them in arrays and outputs again
        according to user role.

Structure

This is the basic structure of the plugin and the containing files, starting from the plugin folder ‘category-colors’.

• eru-index.php (main plugin file)
• eru-style.css (main css file)
• documentation (folder)
  • assets (folder)
    • …blueprint css files and images for this explanation file
  • index.html (this file)
  • screenshots (folder)
    • … (screenshots)

Please do not edit or extend these functions.

D) JavaScript – top

1. jQuery is a Javascript library that greatly reduces the amount of code that you must write.
2. I have written a small jQuery script to add to the Options page, which simply toggles a class in a

   to open or close it. It looks like this;

   jQuery(document).ready( function($) {
   		$("div.postbox h3").click(function () {
    $(this).parent(".postbox").toggleClass("closed"); });
   	});
