问题 2。

我现在在代码未将实际 ID 号输入到查询中时遇到错误...

这里是错误:

查询错误:您的 SQL 语法有误；查看与您的 MySQL 服务器版本对应的手册，了解在第 1 行的 '' 附近使用的正确语法

代码已更新以显示新代码。 (再次)这次有一个隐藏的脚本，以及一些其他的调整。我对让它发挥作用几乎失去了希望。

Issue 1 Solved:    
This line of code is brining back and error: 

        $query = "UPDATE ncmr SET ab = '$ab', date = '$date', part = '$part', rev = '$rev' , partdesc = '$partdesc' , ncmrqty = '$ncmrqty' , comp = '$comp' , ncmrid = '$ncmrid' , rma = '$rma' , jno = '$jno' , fdt = '$fdt' , cof = '$cof' , fab1 = '$fab1' , fab2 = '$fab2' , fab3 = '$fab3' , non = '$non' , dis = '$dis' , comm = '$comm' , caad = '$caad' , po = '$po' , pod = '$pod' , dri = '$dri'  WHERE id = "$_GET['id']"";

    The error is: 

    **Parse error: syntax error, unexpected T_VARIABLE in /home/pawz/public_html/kaboomlabs.com/testbed/edit.php on line 49**

I can't figure out why it is doing it, if someone can show me my mistake it be greatlyfully appreciated.

好的，这是完整的代码。

最佳答案

您需要在 $_GET['id'] 之前和之后使用连接运算符 .。或者嵌入到字符串中:

    ".... WHERE id = {$_GET['id']}";

(请注意，您的 $_GET['id'] 未经过清理并直接从网络输入中获取。这不是最好的做法)。
