Advanced configuration via config.php file

Basic set of Aurora configuration options is defined in settings.xml file. However, Aurora PHP also allows for low-level configuration. The file used for this is data/settings/config.php and it's also used when configuring plugin API.

Just like settings.xml file, config.php is located in the data directory and thus is not affected during product installation upgrades.

By default, config.php file contains a number of predefined values. Specifying a value for particular configuration options means adding pair of key and value according to regular PHP syntax, e.g.:

return array(
	'plugins.voice-message' => true,
	...
);

Below, you'll find a list of options currently supported. In case if the value is not explicitly specified in data/settings/config.php file, default values are retrieved from libraries/afterlogic/common/config.php file. This file is for reference purposes only: do not modify it!

log.log-file

File used for webmail logging.
Default value: "log-$sCurrentDate.txt"

log.event-file

File used for users activity logging.
Default value: "event-$sCurrentDate.txt"

Both the above options use $sCurrentDate value which may be redefined in the same config.php file according to date function syntax:

$sCurrentDate = date('Y-m-d');
