Usage

DatabaseConnecting Event

The ShiftOneLabs\LaravelDbEvents\Extension\Database\Events\DatabaseConnecting event allows you to hook into the database connection lifecycle before the connection is established. Additionally, this event provides you the ability to modify the configuration used for the connection, as well as completely cancel the connection attempt.

Attributes

The DatabaseConnecting event provides three public attributes:

Attribute Description
public $connector The Connector object making the connection. This package extends each of the built-in connectors.
public $connectionName The name of the selected database connection configuration.
public $config The configuration array used to connect to the database.

Example:

Modifying Connection Configuration

The configuration for your database connections is usually stored in your config/database.php file (in conjunction with your .env file). If, however, you need to dynamically modify the configuration used for the connection, this can be done inside a DatabaseConnecting event listener. Any changes made to the configuration in the event listener will be used for the database connection.

Example:

Cancelling the Connection

There may be situations where you would like to prevent the database from attempting the connection. In this case, the database connection attempt can be cancelled by returning false from a DatabaseConnecting event listener. If the database connection is cancelled, a ShiftOneLabs\LaravelDbEvents\Exceptions\ConnectingException runtime exception will be thrown.

Example:

DatabaseConnected Event

The ShiftOneLabs\LaravelDbEvents\Extension\Database\Events\DatabaseConnected event allows you to hook into the database connection lifecycle after the connection is established. Additionally, this event provides access to the final configuration used for the connection, as well as the connection itself.

Attributes

The DatabaseConnected event provides four public attributes:

Attribute Description
public $connector The Connector object making the connection. This package extends each of the built-in connectors.
public $connectionName The name of the selected database connection configuration.
public $config The configuration array that was used to connect to the database.
public $pdo The connected PDO (or potentially Doctrine\DBAL\Driver\PDOConnection, as of 5.3) object.
