mysqli

和/或

PDO

函数。

显示$checks是什么。我猜是一个数组？$checks=内爆（“，”，数组映射（'doubleval'，$请求['check']）；对$check或$res进行var_转储吗？这些代码毫无意义。什么是

$DB

？看起来您正在尝试将一些数据库抽象类与原始mysql查询混合。

$Connect = @mysql_connect($DB_Server, $DB_Username, $DB_Password) or die("Couldn't connect to mysql:<br>" . mysql_error() . "<br>" . mysql_errno());

$Db = @mysql_select_db($DB_DBName, $Connect) or die("Couldn't select database:<br>" . mysql_error(). "<br>" . mysql_errno());


//$sql = "Select * from $DB_TBLName WHERE Delivery_no = '$_REQUEST[Delivery_no]'" ;


    $checks = implode(",",array_map('strval', $_REQUEST['check']));

    if(isset($_POST['submit']))
            {
