Acquia require line

Acquia require line

The code varies according to the database that you select for the specific Drupal site instance.

To obtain and add this code to the settings.php file, follow the instructions in Configuring your application to use environment databasesConfiguring your application to use environment databases.

For example, by default, the config_sync_directory value is set to sits/default/files/config_xxxxx. To change this value, you must include the Acquia require line and add your custom line to override the system-defined value. The following code snippet demonstrates the method to override the system-defined value for config_sync_directory with config directory above the docroot.

// Start of Acquia require line code:
if (file_exists('/var/www/site-php')) {
  require('/var/www/site-php/myappname/mydatabasename-settings.inc');
}
// End of Acquia require line code.

// Example: Override the config sync directory. Point to a folder outside docroot.
$settings['config_sync_directory'] = $app_root . '/../config/' . basename($site_path);

The file added by the Acquia require line performs the following functions:

• Ensures that a valid version of Drupal core is installed.
• Determines what version of Drupal core is in use.
• Establishes the trusted host patterns for Drupal.
• Establishes the Memcached infrastructure and connection information.
• Builds all of the database connection information.
• Suppresses error reporting in the production environment.
• Sets the location of temporary files, including the Twig caches.
