Contents

The WordPress Plugin Boilerplate includes the following files:

  • .gitignore. Used to exclude certain files from the repository.
  • CHANGELOG.md. The list of changes to the core project.
  • README.md. The file that you’re currently reading.
  • A plugin-name directory that contains the source code - a fully executable WordPress plugin.

Features

  • The Boilerplate is based on the Plugin API, Coding Standards, and Documentation Standards.
  • All classes, functions, and variables are documented so that you know what you need to be changed.
  • The Boilerplate uses a strict file organization scheme that correspond both to the WordPress Plugin Repository structure, and that make it easy to organize the files that compose the plugin.
  • The project includes a .pot file as a starting point for internationalization.

Installation

The Boilerplate can be installed directly into your plugins folder "as-is". You will want to rename it and the classes inside of it to fit your needs.

Note that this will activate the source code of the Boilerplate, but because the Boilerplate has no real functionality so no menu items, meta boxes, or custom post types will be added.

Template File Loaders in Plugins

Template file loaders like this are used in a lot of large-scale plugins in order to provide greater flexibility and better control for advanced users that want to tailor a plugin’s output more to their specific needs.

WordPress.org Preparation

The original launch of this version of the boilerplate included the folder structure needed for using your plugin on the WordPress.org. That folder structure has been moved to its own repo here: https://github.com/DevinVinson/Plugin-Directory-Boilerplate

Recommended Tools

i18n Tools

The WordPress Plugin Boilerplate uses a variable to store the text domain used when internationalizing strings throughout the Boilerplate. To take advantage of this method, there are tools that are recommended for providing correct, translatable files:

Any of the above tools should provide you with the proper tooling to internationalize the plugin.

Important Notes

Licensing

The WordPress Plugin Boilerplate is licensed under the GPL v2 or later; however, if you opt to use third-party code that is not compatible with v2, then you may need to switch to using code that is GPL v3 compatible.

For reference, here's a discussion that covers the Apache 2.0 License used by Bootstrap.

Includes

Note that if you include your own classes, or third-party libraries, there are three locations in which said files may go:

  • plugin-name/includes is where functionality shared between the admin area and the public-facing parts of the site reside
  • plugin-name/admin is for all admin-specific functionality
  • plugin-name/public is for all public-facing functionality

Note that previous versions of the Boilerplate did not include Plugin_Name_Loader but this class is used to register all filters and actions with WordPress.

The example code provided shows how to register your hooks with the Loader class.

What About Other Features?

The previous version of the WordPress Plugin Boilerplate included support for a number of different projects such as the GitHub Updater.

These tools are not part of the core of this Boilerplate, as I see them as being additions, forks, or other contributions to the Boilerplate.

The same is true of using tools like Grunt, Composer, etc. These are all fantastic tools, but not everyone uses them. In order to keep the core Boilerplate as light as possible, these features have been removed and will be introduced in other editions, and will be listed and maintained on the project homepage

Credits

The WordPress Plugin Boilerplate was started in 2011 by Tom McFarlin and has since included a number of great contributions. In March of 2015 the project was handed over by Tom to Devin Vinson.

The current version of the Boilerplate was developed in conjunction with Josh Eaton, Ulrich Pogson, and Brad Vincent.

The homepage is based on a design as provided by HTML5Up, the Boilerplate logo was designed by Rob McCaskill of BungaWeb, and the site favicon was created by Mickey Kay.
