来自此链接 Echo problem when a different user logs in我之前发布的，我设法解决或解决了我的问题。但不知何故，发生了一个小错误。虽然我的管理页面工作正常，但我的 super 管理员和其他帐户开始输出错误(尽管它们并不是真正的错误)。员工id和员工姓名在 super 管理员页面和其他帐户中没有回显，但回显了标题(文件上传)、文件日期和状态。
//what i meant to say was, this is what the echo suppose to look like:
*EmployeeID* *EmployeeName* *Title* *FileDate* *Status*

this is the set of codes that i think might have caused the problem,i will put a remark one which if statement the problem i think causes error

我希望有人能帮我弄清楚是什么导致了这个输出。 :( 已经花了一个多小时弄明白了。感谢那些会回复的人。

最佳答案
在这两行中，如果员工 ID 和姓名与从数据库中检索到的 ID 和姓名相匹配，您实际上是在删除它们:
$emp_id=$emp_id==$row['employee_id']?"":$row['employee_id'];
$emp_name=$emp_name==$row['employee_name']?"":$row['employee_name'];
我怀疑你是否想改为这样做:
$emp_id = ($emp_id==$row['employee_id']) ? $emp_id : $row['employee_id'];
$emp_name = ($emp_name==$row['employee_name']) ? $emp_name : $row['employee_name'];
