                    echo 'Error: ' . $e->getMessage();
            }

        public function __sleep () {
            unset($this->conn);
        }
    }


    }

查询不起作用。以前的每个函数都有效，但是当我尝试通过sql查询INSERT表时，没有任何事情发生。

Worker是一个很好的对象，然后我分配了一些POST数组，也可以正常工作然后我尝试saveWorker但它什么都没有。

调用行：

 var_dump($worker);
 if (isset($worker)) echo 'worker is set';
 if (isset($worker->conn)) echo 'thers connection is set';
 $worker->saveWorker('workers');

增加了一行：

 echo "\nPDO::errorInfo():\n";
 print_r($stmt->errorInfo());
 print_r($this->conn->errorInfo());
 echo "end of error info";

它给了我：

PDO::errorInfo(): 
Array ( [0] => ) Array ( [0] => 00000 )
end of error info

Answer 1

$stmt->execute()返回boolean值(Manual)。尝试，

$results = $stmt->execute();
if($results !== FALSE)  {
 return 'Dodano: '.$ilosc.' rekordow';
} else {
 return 'Wystapil blad podczas dodawania rekordow!';
 }

此外，您无法绑定tablename。

INSERT查询不起作用，空数组？
