Question

被困在这里一段时间。

我在尝试运行代码时收到此错误：

警告：PDOStatement :: execute（）：SQLSTATE [HY093]：参数无效 number：参数未定义 /Applications/XAMPP/xamppfiles/htdocs/ProjectWebSite/php/PDO.php on 第111行

第111行是代码的第一行

$result1 = $query1->execute( array( ':transactionID'=>$transactionID, ':personalID'=>$array['personalID'], 
            ':description'=>$array['description'], ':cost'=>$array['cost'], ':datetime'=>$array['datetime'] )  );




function createTransaction($array){
    $db = connection();
    $stmt = $db->prepare("Select MAX(`transactionID`)+1 AS transactionID FROM transaction ");
    $stmt->execute();
    $transactionID = null;
    $results = $stmt->fetchAll(); 
    foreach ($results as $result) {
        $transactionID =$result['transactionID'];
    }

    if(isset($transactionID)){
        $sql = "INSERT INTO `transaction`(`transactionID`, `personalID`, `description`, `cost`, `dateTime`)"
            . " VALUES (:transactinID,:personalID,:description,:cost,CAST(:datetime AS DATETIME)";
        $query1 = $db->prepare( $sql );

        $result1 = $query1->execute( array( ':transactionID'=>$transactionID, ':personalID'=>$array['personalID'], 
            ':description'=>$array['description'], ':cost'=>$array['cost'], ':datetime'=>$array['datetime'] )  );
        var_dump($result1);
        if ( $result1 ){
     return $transactionID;
        }
             return null;
    }
}

Answer 1

您的查询中有拼写错误：

:transactinID应为:transactionID

Answer 2

很简单，你有一个错字：
替换：

$sql = "INSERT INTO `transaction`(`transactionID`, `personalID`, `description`, `cost`, `dateTime`)"
            . " VALUES (:transactinID,:personalID,:description,:cost,CAST(:datetime AS DATETIME)";

使用：

$sql = "INSERT INTO `transaction`(`transactionID`, `personalID`, `description`, `cost`, `dateTime`)"
            . " VALUES (:transactionID,:personalID,:description,:cost,CAST(:datetime AS DATETIME)";

参数号无效：未定义参数
