Log workflow execution to a file

This example shows how to log workflow execution into a file.

1. <?php
2. // Set up the logfile writer.
3. $writer = new ezcLogUnixFileWriter( '/tmp/workflow.log' );
5. $log = ezcLog::getInstance();
6. $mapper = $log->getMapper();
7. $filter = new ezcLogFilter;
8. $rule = new ezcLogFilterRule( $filter, $writer, true );
9. $mapper->appendRule( $rule );
11. // Set up database connection.
12. $db = ezcDbFactory::create( 'mysql://test@localhost/test' );
14. // Set up workflow definition storage (database).
15. $definition = new ezcWorkflowDatabaseDefinitionStorage( $db );
17. // Load latest version of workflow named "Test".
18. $workflow = $definition->loadByName( 'Test' );
20. // Set up database-based workflow executer.
21. $execution = new ezcWorkflowDatabaseExecution( $db );
23. // Pass workflow object to workflow executer.
24. $execution->workflow = $workflow;
26. // Attach logfile writer as a listener.
27. $execution->addListener( new ezcWorkflowEventLogListener( $log ) );
29. // Start workflow execution.
30. $id = $execution->start();
31. ?>
