Logger bridge for Contao Open Source CMS

This bridge provide PSR-3 logger support for Contao Open Source CMS. The logger is available via the dependency injection container.

By default the logger use two handlers.

• An contao syslog handler, that write log entries to the system log database.
• And an stream handler, that write log entries to system/logs/contao.log.

By default it use Monolog as implementation, but it is designed to be replaceable with any PSR-3 compatible logger implementation.

Access and use the logger

global $container;

/** @var \Psr\Log\LoggerInterface */
$logger = $container['logger'];
$logger->emergency('Some extreme critical message');

Logger configuration

Receive and change the default log level

global $container;

// receive default log level
$level = $container['logger.default.level'];

// change default log level
$container['logger.default.level'] = \Psr\Log\LogLevel::WARNING;

Define default log handlers

The default log handlers are stored in $container['logger.default.handlers'] containing a list of handler services.

global $container;

// receive the default log handlers array (its an ArrayObject instance)
$handlers = $container['logger.default.handlers'];

// remove the contao syslog handler
foreach ($handlers as $index => $serviceKey) {
	if ($serviceKey == 'logger.handler.contao') {
		unset($handlers[$index]);
		break;
	}
}

// add a custom handler
$container['logger.handler.custom'] = function($container) {
	$factory = $container['logger.factory.handler.stream'];
	// store in /var/log/critical.log
	return $factory('/var/log/critical.log', \Psr\Log\LogLevel::CRITICAL);
}
$handlers->append('logger.handler.custom');

Create your own logger

global $container;

// register a handler
$container['logger.handler.custom'] = function($container) {
	$factory = $container['logger.factory.handler.stream'];
	// store in system/logs/critical.log
	return $factory('critical.log', \Monolog\Logger::CRITICAL);
}

// register your logger
$container['logger.custom'] = function($container) {
	// using the logger factory
	$factory = $container['logger.factory'];
	$logger = $factory('contao', array('logger.handler.custom'));

	return $logger;
};

// receive your logger
$logger = $container['logger.custom'];
