Question

这让我感到沮丧超过一个小时，任何帮助都会受到赞赏。

我已使用下面的评论“标记”违规代码

        $hostt = "localhost";
$db_database = "dekit_ryan";
$db_username = "dekit_ry";
$db_password= "s%g0oM";


$link = mysqli_connect($hostt , $db_username, $db_password, $db_database);

if (!$link) {
    printf("Unable to connect to DB, the error is: %s\n", mysqli_connect_error());
    exit();
}


// ************* Problem seems to be with the below line ***********
   $stmt = mysqli_prepare($link, "INSERT INTO campaign(cname,public_ref_name,redirect_to) VALUES (?, ?,  ?)");

        mysqli_stmt_bind_param($cname, $pub_ref_name, $url);
        mysqli_stmt_execute($stmt);

        // Check if the row was successfully inserted or spit out an error
        if(mysqli_stmt_affected_rows($stmt) != 1)
        {
            return "Error: Problem inserting a record into the database, exiting..." . mysqli_errno($link);
            exit;
        }

当我运行脚本时，我总是得到：

警告：mysqli_stmt_bind_param（）要求参数1为mysqli_stmt，第44行/home/dekit3/public_html/adTracking/classes/AdsTracking.php中给出的字符串

错误：将记录插入数据库时出现问题，退出... 0

Answer 1

该行

 mysqli_stmt_bind_param($cname, $pub_ref_name, $url);

要求您使用第一个参数$stmt变量。

修改

请查看manual中的示例2。

Answer 2

您正在为mysqli_stmt_bind_param设置不正确的参数。它应该是：

mysqli_stmt_bind_param($stmt, 'sss', $cname, $pub_ref_name, $url);

根据数据库中的数据类型更改'sss'。
