ClassicPress Plugin Development: Format of a Plugin Header

ClassicPress PluginsThis post is part of the ClassicPress Plugin Development series in which I am going to look at both best practice for developing plugins and how I approach some requirements as well as some of the functions I commonly use.

As with the readme.txt file, the main plugin file needs a header containing information related to the plugin. The bare minimum which is needed in the header is the plugin name:

 * Plugin Name: {plugin name}

The fields which can be used are:

  • Plugin Name: The name of your plugin, which will be displayed in the Plugins list in the ClassicPress admin dashboard.
  • Plugin URI: The unique home page of the plugin
  • Description: A short description of the plugin which will be displayed in the Plugins section in the admin dashboard. It should be shorter than 140 characters.
  • Version: The current version number of the plugin, such as 1.0.0 or 1.0.3.
  • Requires at least: The lowest ClassicPress version that the plugin will work on.
  • Requires PHP: The minimum required PHP version.
  • Author: The name of the plugin author (separate multiple authors with commas).
  • Author URI: The author’s website or profile on another website.
  • License: The short name (slug) of the plugin’s license (e.g. GPLv2).
  • License URI: A link to the full text of the license (e.g.
  • Text Domain: The gettext text domain of the plugin. More information can be found in the Text Domain section of the How to Internationalize your Plugin page.
  • Domain Path: The domain path tells ClassicPress where to find the translations.

The below example is what I use for my plugins:

 * ------------------------------------------------------------------------------
 * Plugin Name: {plugin name}
 * Description: {short description}
 * Version: {version}
 * Author: {author}
 * Author URI: {author url}
 * Plugin URI: {plugin url}
 * Text Domain: {text domain}
 * Domain Path: {domain path}
 * ------------------------------------------------------------------------------
 * This is free software released under the terms of the General Public License,
 * version 2, or later. It is distributed WITHOUT ANY WARRANTY; without even the
 * text of the license is available at
 * ------------------------------------------------------------------------------

In the above example, the text in braces {} would be replaced with the required text.
