{"version":"1.0","type":"rich","title":"Add try/catch","description":"This example shows how to safely handle database insert operations within a transaction using PHP exception handling. The code opens a transaction with `db_transaction()`, then attempts to insert a record into the `linkchecker_bean` table via the Drupal database abstraction layer’s `db_insert()` method. If the insert throws an exception, a catch block rolls back the transaction with `$txn->rollback()` and logs the error using `watchdog_exception()`. The data source is the Drupal database, and the approach relies on standard try/catch semantics to ensure atomicity.","provider_name":"VizHub AI Studio","provider_url":"https://next.vizhub.com","html":"<iframe src=\"https://next.vizhub.com/viz/gist-3a981a76b3d4b93d50091bf85ef4e43f?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"1\"></iframe>","width":960,"height":500,"cache_age":3600}
