解析错误：语法错误，第 46 行 /home/buyerherel/public_html/ordertracking/backend/processeditship.php 中的意外 T_STRING

有什么帮助吗？

不确定问题出在哪里，但这真的很令人沮丧，因为我正处于项目编辑部分的最后一步，它允许我更新表格。我故意在这里省略了引号 - trackingnumber =$trackingnumber, 所以这不是问题..

【问题讨论】：

因为$sql的声明末尾没有关闭引号？
您的一条查询已（不小心？）被您删除。它以 `OrderNo = $OrderID` 结尾，暗示还有另一个 WHERE 条件要遵循
看颜色...

【解决方案1】：

$sql 中没有结尾符号 "。应该是：

$sql = "
    UPDATE
        ordertracking
    SET
        trackingnumber =$trackingnumber,
        `trackingURL` = '" . $trackingURL . "',
        `CustomerName` = '" . $CustomerName . "',
        `LocationShipped` = '" . $LocationShipped . "',
        `user_email` = '" . $user_email . "',
        `ShipmentDate` = '" . $ShipmentDate . "',
        `ShipmentMode` = '" . $ShipmentMode . "',
        `CurrentStatus` = '" . $CurrentStatus . "'
    WHERE
        OrderNo = $OrderID"; // < missing ";

感谢您的回复..但现在我得到“无法输入数据：您的 SQL 语法有错误；请查看与您的 MySQL 服务器版本相对应的手册以获取正确的语法使用在第 12 行的“WHERE 'OrderNo' = 12345888884' 附近”
WHERE 前不应该是逗号
还没看过，谢谢@JeffHawthorne。答案已更新
杰夫，我欠你一杯啤酒 :) 谢谢大家的帮助！现在会带着更多问题回来:)

【解决方案2】：

您使用了, 而不是;，忘记了一些"。

$sql = "
    UPDATE
        `ordertracking`
    SET
        `trackingnumber` = " . $trackingnumber . ",
        `trackingURL` = '" . $trackingURL . "',
        `CustomerName` = '" . $CustomerName . "',
        `LocationShipped` = '" . $LocationShipped . "',
        `user_email` = '" . $user_email . "',
        `ShipmentDate` = '" . $ShipmentDate . "',
        `ShipmentMode` = '" . $ShipmentMode . "',
        `CurrentStatus` = '" . $CurrentStatus . "',
    WHERE
        `OrderNo` = " . $OrderID; // ; instead of ,

$result1 = mysql_query($query1);

【解决方案3】：

只需替换第 50 行

   OrderNo = $OrderID";

通过此代码

【解决方案4】：

两个问题

关闭双引号
删除 $OrderID 后面的逗号

所以改变

$sql = "
UPDATE
    ordertracking
SET
    trackingnumber =$trackingnumber,
    `trackingURL` = '" . $trackingURL . "',
    `CustomerName` = '" . $CustomerName . "',
    `LocationShipped` = '" . $LocationShipped . "',
    `user_email` = '" . $user_email . "',
    `ShipmentDate` = '" . $ShipmentDate . "',
    `ShipmentMode` = '" . $ShipmentMode . "',
    `CurrentStatus` = '" . $CurrentStatus . "',
WHERE
    OrderNo = $OrderID,

到

$sql = "
UPDATE
    ordertracking
SET
    trackingnumber =$trackingnumber,
    `trackingURL` = '" . $trackingURL . "',
    `CustomerName` = '" . $CustomerName . "',
    `LocationShipped` = '" . $LocationShipped . "',
    `user_email` = '" . $user_email . "',
    `ShipmentDate` = '" . $ShipmentDate . "',
    `ShipmentMode` = '" . $ShipmentMode . "',
    `CurrentStatus` = '" . $CurrentStatus . "',
WHERE
    OrderNo = $OrderID";
