action

Start a transaction.

• callback [function]

  The transaction wrap for executing queries.

$database->action(function($database) {

	$database->insert("account", [
		"name" => "foo",
		"email" => "bar@abc.com"
	]);

	$database->delete("account", [
		"user_id" => 2312
	]);

	// If you found something wrong, just return a false value to roll back the whole transaction.
	if ($database->has("post", ["user_id" => 2312])) {
		return false;
	}
});

Accessing data outside of action

Create a result variable and refer to the action callback with the keyword `use`, and you can get data back after when you assign it from inside.

$result = "";

$database->action(function($database) use (&$result) {

    $database->insert("account", [
        "user_name" => "foo"
    ]);

    $newId = $database->id();

    $result = "Account is created, and the id is {$newId}.";
});

echo $result;
