Installation

Install the latest version with

composer require moddix/wp-logger

Usage

1. Create a file in the mu-plugins directory of your Bedrock project (e.g., wp-logger.php) and include the following code:

use Moddix\WpLogger\Configurator;
use Moddix\WpLogger\WpLogger;
use Monolog\Handler\StreamHandler;
use Monolog\Level;
use Monolog\Formatter\JsonFormatter;

// Create a Configurator instance
$configurator = new Configurator();

// Example: Set handler to output logs to stdout in JSON format
$handler = new StreamHandler('php://stdout', Level::Debug);
$handler->setFormatter(new JsonFormatter(JsonFormatter::BATCH_MODE_NEWLINES, true));

// push the handler to the configurator
$configurator->pushHandler($handler);

// Example: Add a processor to add extra data to each log record
$configurator->pushProcessor(function ($record) {
    $record->extra['dummy'] = 'Hello world!';

    return $record;
});

// Example: Add a subscriber to log wp_die events, see HookSubscribersInterface for more options
$configurator->addSubscriberClasses([
    Moddix\WpLogger\HookSubscribers\WpDieSubscriber::class,
]);

// Boot the logger with the configurator
WpLogger::boot($configurator);

1. Use the facade to log messages in your WordPress code:

\Moddix\WpLogger\Log::info('This is an info message.');
\Moddix\WpLogger\Log::warning('This is a warning message.');
\Moddix\WpLogger\Log::error('This is an error message.');

\Moddix\WpLogger\Log::debug('This is a debug message with context.', ['key' => 'value']);

\Moddix\WpLogger\Log::log('info', 'This is a log message with dynamic level.', ['key' => 'value']);
