PHP Constants

PHP constants store fixed values that remain the same throughout your site. They are automatically global, which is ideal for values that need to be accessed in multiple places.

If you use a non-standard WordPress setup, such as Bedrock or Trellis, Kinsta may not be able to locate the DB_PASSWORD variable and, therefore, is unable to update the database password when you:

• Add a new site by cloning an existing environment
• Add a staging environment by cloning an existing environment
• Push staging to live
• Restore a backup
• Change the database password in MyKinsta

To resolve this issue, Kinsta provides the SERVER_SECRET_DB_PASSWORD PHP constant for use on the Kinsta servers. When you define this constant within the config.php file, MyKinsta uses it to identify your site’s database password. You can define it as follows:

define('DB_PASSWORD', defined('SERVER_SECRET_DB_PASSWORD') ? SERVER_SECRET_DB : 'asdijfhkjasdbfkjhbajiksd' );

You can define the following PHP constants to use with Kinsta servers:

• SERVER_SECRET_DB_USER
• SERVER_SECRET_DB_PASSWORD
• SERVER_SECRET_DB_HOST
• SERVER_SECRET_DB_NAME

For example, you can define the constants in the config.php file as follows:

define('DB_NAME', defined('SERVER_SECRET_DB_NAME') ? SERVER_SECRET_DB_NAME : 'newsitetest');
define('DB_USER', defined('SERVER_SECRET_DB_USER') ? SERVER_SECRET_DB_USER : 'newsitetest');
define('DB_PASSWORD', defined('SERVER_SECRET_DB_PASSWORD') ? SERVER_SECRET_DB : 'asdijfhkjasdbfkjhbajiksd' );
define('DB_HOST', defined('SERVER_SECRET_DB_HOST') ? SERVER_SECRET_DB_HOST : 'localhost');

Alternatively, you can define the constants as follows:

define('DB_NAME',SERVER_SECRET_DB_NAME);
define('DB_USER',SERVER_SECRET_DB_USER);
define('DB_PASSWORD',SERVER_SECRET_DB_PASSWORD);
define('DB_HOST',SERVER_SECRET_DB_HOST);
