这不起作用:
public function persist( Forwarding $Forwarding ) {
$sql = "INSERT INTO forwarding ( inbound_id ) VALUES ( :inbound_id )";
$statement = $this->pdo->prepare( $sql );
$statement->bindValue(':inbound_id', $Forwarding->getInboundId() );
$query = $statement->execute();
}
因为边界值总是NULL
. 不能使用回调来绑定 PDO 的准备语句的值吗?
