Php Codeigniter 3登录问题直接进入页面，无需验证

我有一个问题，每次我点击登录它只是带我到我的页面，它似乎没有检查，看看是否输入用户名或密码。我不确定问题出在哪里，我将行

if（$this->form\u validation->run（）==FALSE）

更改为true，然后在输入正确密码时，我被重定向回登录。我想我只是错过了一些简单的东西。如果有人有想法，任何方向都会有帮助，同时我会不断地找出答案

您正在将数据发送到verifylogin/index，并且随时都在加载规则以进行检查和验证，这两个规则都没有从数据库中进行检查。这就是问题所在。
使用
$this->form\u validation->run（）==FALSE
代替，使用3个
=
符号
 因此，我需要使用checkdatabase来代替verifylogin/checkdatabaseYes，您还应该将逻辑更改为if（语句）{//Dosomethinwhen is true}else{//Dosomethinwhen is false}
