Codeigniter：遇到未捕获的异常类型：ArgumentCountError

Question

尝试编辑内容时出现错误，当我按下更新内容时它会抛出错误 遇到未捕获的异常 类型：ArgumentCountError

消息：函数 Dashboard::contentedit() 的参数太少，在第 514 行的 /home/muanetor/matematika.muanetoraya.com/system/core/CodeIgniter.php 中传递了 0，而预期正好是 1

文件名：/home/muanetor/matematika.muanetoraya.com/application/controllers/Dashboard.php

行号：145

文件：/home/muanetor/matematika.muanetoraya.com/index.php 线路：315 函数：require_once

控制器：

我猜，这个错误只有在你尝试访问控制器时才发生，而没有像

这样的参数

如果你像下面这样访问控制器，应该不会出错

您可以通过将默认值设置为 $id 来解决此问题

public function contentedit($id = -1){
    if($id != -1){
         //put your code here
    }else{
        show_404();
    }
}
