我在从次模态特性中保存Notes部分时遇到了很多麻烦。其他所有东西都可以保存，但笔记不会。我做错了什么?

为什么不使用PDO或MYSQLI代替mysql?如果你使用PDO，你不需要自己"清除"变量:
switch ($theType) {
case "text":
$theValue = ($theValue != "") ? "'" . $theValue . "'" : "NULL";
break;
....
}
可以使用PDO预处理语句:pdostatement
请在这里插入var_dump
var_dump($_POST);
$updateSQL = sprintf ("UPDATE Leads SET Notes = CONCAT_WS(''n', Notes, ''n', %s) WHERE Id=%d",
GetSQLValueString($_POST['Notes'], "text"),
GetSQLValueString($_POST['Id'], "int"));
var_dump( $updateSQL,$_POST['Notes']);
并告诉我们，输出结果是什么
