Composer-enabled WordPress template

This is Pantheon's recommended starting point for forking new WordPress upstreams that work with the Platform's Integrated Composer build process.

Unlike with other Pantheon upstreams, the WordPress core install, which you are unlikely to adjust while building sites, is not in the main branch of the repository. Instead, it is referenced as dependencies within Roots/Bedrock that are installed by Composer.

Early Access software

A product in Early Access denotes a new project or feature set that is in development and available for a limited audience. Some features are stable, but the product is only partially complete and development is still in progress. For more information on support for Early Access projects, refer to our documentation.

Powered by Bedrock

Bedrock is a modern WordPress stack that helps you get started with the best development tools and project structure.

Much of the philosophy behind Bedrock is inspired by the Twelve-Factor App methodology including the WordPress specific version.

Features

Better folder structure
Dependency management with Composer
Easy WordPress configuration with environment specific files
Environment variables with Dotenv
Autoloader for mu-plugins (use regular plugins as mu-plugins)
Enhanced security (separated web root and secure passwords with wp-password-bcrypt)

How to use this project

There are two main ways to interact with this project template. Using the Pantheon-maintained WordPress Composer Managed upstream or forking this repository to create a custom upstream.

Using the Pantheon WordPress Composer Managed upstream (recommended)

Use Terminus to create a site from the Pantheon upstream:

terminus site:create --org ORG --region REGION -- <site_name> <label> "WordPress (Composer Managed)"

In the Dev environment, click Visit Development Site and follow the prompts to complete the CMS installation.
Clone the site locally and run composer install.

Fork this repository to create a custom upstream (advanced)

Note: It's highly recommended that you use the Pantheon-maintained upstream in favor of creating and managing a custom upstream so you can be sure to receive the latest updates. Managing your own custom upstream means that you assume ownership of the upstream and all changes made to it and assumes that you will manage all updates to the upstream.

Fork the pantheon-upstreams version of this repository into your own (or your organization's) GitHub profile.
Create a branch off of main called master and set this to the default branch for your custom upstream.
Add a new Custom Upstream on the Pantheon Dashboard.
Create a new WordPress site from the Upstream.

On the use of `master` for custom upstreams

We acknowledge and apologize for the continued use of the master branch name. We understand that the use of the word master is offensive and hurtful to people in our community, and changing branch names to main has been on our roadmap for a long time. We strive to be an inclusive platform and we know that until we are able to completely rename all of our master branch names to something less offensive, we still have work to do. Unfortunately in this context, at a platform level, the use of master is hard-coded as the expected default branch name and therefore, when creating custom upstreams off of this repository (which uses main by default), a master branch is necessary for the platform to recognize the upstream without errors or the assistance of Customer Support. We hope this is a temporary solution and that the platform-level changes can happen soon, and we appreciate your continued patience as we transition our default branch names. Alternately, you can use a CI-based build workflow to automate pushing your code to master on the Pantheon side, but keep the main branch naming scheme (or any other branch name) in your custom upstream's repository.

Using Roots Bedrock

Environment Variables

Bedrock makes use of an .env file to store environment variables. Pantheon takes care of many of these variabled in .env.pantheon. You may set your own environment variables in a new .env or environment variables that are local-only in .env.local using the .env.example as a guide. Wrap values that may contain non-alphanumeric characters with quotes, or they may be incorrectly parsed.

Database variables
- DB_NAME - Database name
- DB_USER - Database user
- DB_PASSWORD - Database password
- DB_HOST - Database host
- Optionally, you can define DATABASE_URL for using a DSN instead of using the variables above (e.g. mysql://user:[email protected]:3306/db_name)
WP_ENV - Set to environment (development, staging, production)
WP_HOME - Full URL to WordPress home (https://example.com)
WP_SITEURL - Full URL to WordPress including subdirectory (https://example.com/wp)
AUTH_KEY, SECURE_AUTH_KEY, LOGGED_IN_KEY, NONCE_KEY, AUTH_SALT, SECURE_AUTH_SALT, LOGGED_IN_SALT, NONCE_SALT
- Generate with wp-cli-dotenv-command
- Regenerate with Bedrock's WordPress salts generator

WordPress Config

The wp-config.php file is located in the web directory. As with other WordPress sites on Pantheon, much of this is taken care of for you in wp-config-pantheon.php. Application-level configuration takes place in config/application.php. This can be referenced as a guide to understand how the constants are set up and how the .env files work, but modifying this file may result in merge conflicts and is not recommended. Any configuration changes should be made to your wp-config.php file directly.

You can learn more about WordPress configuration with Bedrock in the Bedrock Configuration docs.

Understanding the WordPress codebase

Bedrock installs WordPress as a required package so updates can be managed by Composer. As such, the contents of the wp-content directory have been moved outside the WordPress codebase so changes can be made safely to files within those directories without conflicts.

Theme are installed into web/app/themes/.
Plugins are installed into web/app/plugins.
Must-use plugins are installed into web/app/mu-plugins.
The WordPress admin dashboard is available at https://example.com/wp/wp-admin/

Using Composer to manage plugins and themes

Packagist is a repository of Composer packages that are available by default to projects managed by Composer. Packagist libraries receive updates from their source GitHub repositories automatically.

WPackagist is a Packagist-like mirror of the WordPress.org plugin and theme repositories and is included with Bedrock out of the box.

You may install packages from Packagist or WPackagist without any additional configuration using composer upstream-require.

Requiring a package from Packagist

Some WordPress developers push their packages to Packagist in addition to the WordPress plugin and theme repositories. In this way, it may be beneficial to pull those packages directly from Packagist to get the latest code directly from the source.

composer upstream-require yoast/wordpress-seo

Packages that are flagged as wordpress-plugin, wordpress-theme or wordpress-muplugin in their composer.json files will be installed automatically in the appropriate web/app/ directory by Composer.

Requiring a package from WPackagist

For all other plugins and themes that are not managed on Packagist, you can use composer upstream-require as well, using wpackagist-plugin or wpackagist-theme as the vendor and the plugin or theme slug as the package name.

composer upstream-require wpackagist-theme/twentytwentytwo

composer upstream-require wpackagist-plugin/advanced-custom-fields

Contributing

Contributions are welcome in the form of GitHub pull requests. However, the pantheon-upstreams/wordpress-composer-managed repository is a mirror that does not directly accept pull requests.

Instead, to propose a change, please fork pantheon-systems/wordpress-composer-managed and submit a PR to that repository.
