PHP PDO准備語句中的錯誤

Question

try 
{

    $stmt = $conn->prepare(" Update site_users SET users_first_name = :users_first_name, users_last_name = users_last_name
    ,users_email_verified = :users_email_verified , users_password = :users_password, users_dob_day = :users_dob_day, users_dob_month = :users_dob_month
    ,users_dob_year = :users_dob_year, users_password_1 = :users_password_1, users_registration_time= :users_registration_time 
    WHERE users_email = :users_email");

    $stmt->bindParam(':users_first_name', $_POST["firstname"] , PDO::PARAM_STR);
    $stmt->bindParam(':users_last_name', $_POST["lastname"]  , PDO::PARAM_STR);
    $stmt->bindParam(':users_email', $_POST["email"] , PDO::PARAM_STR);
    $stmt->bindParam(':users_password', $hashed_password , PDO::PARAM_STR);
    $stmt->bindParam(':users_password_1', $_POST["password"] , PDO::PARAM_STR);
    $stmt->bindParam(':users_email_verified', $users_email_verified , PDO::PARAM_STR);
    $stmt->bindParam(':users_dob_day', $_POST["day"], PDO::PARAM_STR);
    $stmt->bindParam(':users_dob_month', $_POST["month"], PDO::PARAM_STR);
    $stmt->bindParam(':users_dob_year', $_POST["year"], PDO::PARAM_STR);
    $stmt->bindParam(':users_registration_time',$date, PDO::PARAM_STR);

    $stmt->execute();

}

catch(PDOException $e) 
{
        echo "Error: " . $e->getMessage();
}

這是錯誤，代碼echo

錯誤：SQLSTATE [HY093]：無效的參數編號：綁定變量的數量與令牌的數量不匹配

此代碼中的問題出在哪里？

我認為您在users_last_name = users_last_name查詢中缺少:

可能必須是users_last_name = :users_last_name
