问题描述
我目前在如何找到解决方案上遇到麻烦.因此，首先，我将显示项目工作详细信息，但我无法找出为什么它继续获取所有数据(其中存在查询异常)的原因.这样做的问题可能是我无法将ProjectID传递到模型中，因此，它无法识别唯一键，也无法在指定项目中显示详细信息.请帮忙.非常感激. :)顺便说一句，我正在使用代码点火器.我在下面插入我的代码供您查找！谢谢！

I''m currently in troubled on how to find a solution for this. So to start with, i am displaying project work details and I just cant find out why it keeps on fetching all data wherein there exceptions on the query. The problem with that was probably i could not pass the ProjectID into the model and thus, it doesn''t recognize a unique key and doesn''t display details in the specified project. Need help please. Much appreciated. :) BTW i am using code igniter. I am inserting my code below for you to find out! thanks!
