Question

在下面的codeigniter代码中我放置了控制器和型号。在我的会员表中，我有4列考试名称，月份，年份和大学名称。

Exam name month year college name
anna univ feb   2013   kings
anna      sep   2014    srm

现在我的目标是当我登录国王学院时，它会显示特定的大学信息。但是当我更新国王信息时，它也会显示srm信息。请帮助我解决问题。控制器：

Answer 1

你能提供$ this-＆gt; input-＆gt; post（'editcustomer'）的价值吗？
同样在您的控制器中，您最后缺少一个结束括号}。说//功能结束的注释行实际上是else括号的结尾。

更新表中的特定记录将显示表中的其他记录
