composer-wp-config

A plugin for Composer to create the WordPress configuration file which automagically defines constants from a .env file. Also includes path of Composer's autoloader in wp-config.php.

Installation

Via Composer

composer require johnpbloch/wordpress wearerequired/composer-wp-config

Copy .env.example and save it as .env. By default the variables are searched in a .env file in the same directory as wp-config.php .

List of required variables

• _HTTP_HOST (Used when $_SERVER['SERVER_NAME'] is not set, like WP-CLI.)
• DB_NAME
• DB_USER
• DB_PASSWORD
• AUTH_KEY
• SECURE_AUTH_KEY
• LOGGED_IN_KEY
• NONCE_KEY
• AUTH_SALT
• SECURE_AUTH_SALT
• LOGGED_IN_SALT
• NONCE_SALT

See also the list of default constants.

Customize path to .env file

You can override the path(s) with the following extra in your composer.json:

{
    "extra": {
        "wp-config-env-paths": [
            "../",
            "../configs"
        ]
    }
}

Note that the path must be relative to the wp-config.php file. Run composer build-wp-config to rebuild the wp-config.php file.

Features

• Creates wp-config.php one level above the WordPress installation.
• The wp-config.php includes the path to Composer's autoloader.
• Searches for .env file with the help of PHP dotenv.
• Defines all variables as constants unless a constant is already set.
• Defines reasonable default values for database, object cache, debug, URL, and path constants.
• Use {{DIR}} as placeholder in variable values to get it replaced with __DIR__ of wp-config.php.
• Supports URL_DEVELOPMENT, URL_STAGING, and URL_PRODUCTION for WordPress Stage Switcher. Requires at least v2.1.
• Supports loading wp-config-prepend.php before and wp-config-append.php after the default config as part of wp-config.php.
• Loads the WordPress plugin API early so actions and filters can be used.
