Viewing history events
This screenshot show the log view + it also shows the filter function in use: the log only shows event that are of type post and pages and media (i.e. images & other uploads), and only events initiated by a specific user.
Events with different severity
Simple History uses the log levels specified in the PHP PSR-3 standard.
Events have context with extra details
Each logged event can include useful rich formatted extra information. For example: a plugin install can contain author info and a the url to the plugin, and an uploaded image can contain a thumbnail of the image.
Developers can easily log their own things using a simple API:
<?php // This is the easiest and safest way to add messages to the log // If the plugin is disabled this way will not generate in any error apply_filters("simple_history_log", "This is a logged message"); // Or with some context and with log level debug: apply_filters( 'simple_history_log', 'My message about something', [ 'debugThing' => $myThingThatIWantIncludedInTheLoggedEvent, 'anotherThing' => $anotherThing ], 'debug' ); // Or just debug a message quickly apply_filters('simple_history_log_debug', 'My debug message'); // You can olsy use functions/methods to add events to the log SimpleLogger()->info("This is a message sent to the log"); // Add events of different severity SimpleLogger()->info("User admin edited page 'About our company'"); SimpleLogger()->warning("User 'Jessie' deleted user 'Kim'"); SimpleLogger()->debug("Ok, cron job is running!");
