- Getting Started
- Environment Configuration
- Application Configuration
All of the configuration files for October CMS are stored in the config directory. Each option is documented, so feel free to look through the files and get familiar with the options available to you.
It is often helpful to have different configuration values based on the environment the application is running in. To control confguration in different environments, October CMS uses a DotEnv library to make it easy to manage environment variables. These variables can override any values specified in the config directory.
In a fresh installation of October CMS, the base directory will contain a
.env.example file that provides typical values for a local environment. During the installation process, this file will be copied to
.env where you can make any changes.
For example, the database connection can be specified with these variables.
DB_CONNECTION=mysql DB_HOST=127.0.0.1 DB_PORT=3306 DB_DATABASE=database DB_USERNAME=root DB_PASSWORD=
Any variable in your
.env file can be overridden by external environment variables such as server-level or system-level environment variables. For example, in Apache this line can be added to the
SetEnv DB_CONNECTION "mysql"
To recap, configuration values are loaded in this order.
- System environment variables
- Variables in the
- Values in the config PHP files
Important: Never commit your
.envfile to source control because this would be a security risk in the event an intruder gains access to your source control repository, since any sensitive credentials would get exposed.
Here we will cover some common configuration items and their purpose.
The debug setting is found in the
config/app.php configuration file with the
debug parameter. By default, this option looks at the value of the
APP_DEBUG environment variable, which is stored in your
When enabled, this setting will show detailed error messages when they occur along with other debugging features. While useful during development, debug mode should always be disabled when used in a live production site. This prevents potentially sensitive information from being displayed to the end-user.
The debug mode uses the following features when enabled:
- Detailed error pages are displayed.
- Failed user authentication provides a specific reason.
- Combined assets are not minified by default.
- Safe mode is disabled by default.
Important: Always set the
falsein production environments.
The safe mode setting is found in the
config/cms.php configuration file with the
enable_safe_mode parameter. By default, the option sources its value from
CMS_SAFE_MODE which can be added to your
When safe mode is enabled, the PHP code section is disabled in CMS templates to prevent a user from potentially executing malicious code.
This variable can be set to
false. If set to
null, safe mode will activate when debug mode is disabled.
October CMS provides an easy method of protecting your application from cross-site request forgeries. First a random token is placed in your user's session. Then when a opening form tag is used the token is added to the page and submitted back with each request.
While CSRF protection is enabled by default, you can disable it with the
enable_csrf_protection parameter in the
config/system.php configuration file, or the sourced value from
ENABLE_CSRF environment variable.
