Question

我正在尝试将一些数据插入到mysql数据库

$db = new DataBase($config);

// connect to the database RETURNS true if success false if fails
$conn = $db->connect();

// check whether the connection is successfull or not...
if ($db->isConnected())
     {

        //prepare the query
        $query = 'INSERT INTO scoreboard (score) VALUES(:score) WHERE username=:username';
        $bindings =  array(
                         'score'   =>  $score,
                        'username' => ($_SESSION['username'])

                         );


        // call the query function from db class and retrieve the results as an array of rows.
        $results = $db->setData($conn,$query,$bindings);
        if ($results)
            echo "Your Score is Updated!";
        else

            echo "Your Score is Not Updated!";


        }

继承了setData（）的作用：

function setData($conn,$query,$bindings)
{
    try {

            // prepare the query
            $stmt = $conn->prepare($query);

            //binde the query with the data .here the data is $bindings
            $stmt->execute($bindings);

            return ( $stmt->rowCount() > 0 )
                // return the result if the query is success else return false.
                ? $stmt
                : false;
        } 

        catch(Exception $e) {
            // return error if something goes wrong
            return false;
        }


}

每次运行此脚本时，我都会将“您的分数未更新”作为输出。

我哪里错了？

$ _SESSION ['用户名']会造成麻烦吗？

任何有关正确解释的帮助都将受到高度赞赏！

您正在更新或插入？尝试使用phpmyadmin上的静态数据手动查询，然后确保您的会话已设置＆amp;如果插入成功数据则返回true

我如何调试我的查询？
