| 4 | * AI Engine Tasks Examples |
| 5 | * |
| 6 | * This class demonstrates how to use the AI Engine Tasks system programmatically. |
| 7 | * It includes examples of: |
| 8 | * - Simple recurring tasks (Ping Example) |
| 9 | * - Multi-step tasks (Chatbot Test) |
| 10 | * - Task data persistence across runs |
| 11 | * - Error handling and retry logic |
| 12 | * |
| 13 | * TUTORIAL: How to Create Your Own Tasks |
| 14 | * |
| 15 | * 1. Register your task handler: |
| 16 | * add_filter( 'mwai_task_your_task_name', [ $this, 'your_handler' ], 10, 2 ); |
| 17 | * |
| 18 | * 2. Create or ensure your task exists: |
| 19 | * $this->core->tasks->ensure( [ |
| 20 | * 'name' => 'your_task_name', |
| 21 | * 'description' => 'What your task does.', |
| 22 | * 'schedule' => '0 2 * * *', // Cron expression or 'once' |
| 23 | * 'next_run' => '2024-12-25 14:00:00', // Optional: specific time for one-time tasks |
| 24 | * ] ); |
| 25 | * |
| 26 | * 3. Implement your handler: |
| 27 | * public function your_handler( $result, $job ) { |
| 28 | * // $job contains: task_name, task_id, data (persistent), step, step_name |
| 29 | * // Return: [ 'ok' => true/false, 'message' => 'Status', 'data' => [] ] |
| 30 | * } |
| 31 | * |
| 32 | * 4. For multi-step tasks: |
| 33 | * - Return 'step' => N to move to next step |
| 34 | * - Return 'done' => true when complete |
| 35 | * - Data persists across steps automatically |
