登录提供错误

错误的电子邮件ID或密码！

即使给出了正确的凭证即使两个密码字段都匹配，注册也会出错。

“密码”字段与“确认密码”字段不匹配。

这是注册控制器代码。

请咨询，我在Windows 10中运行.XAMPP

我从中获取了代码 http://www.kodingmadesimple.com/2016/06/codeigniter-login-and-registration-tutorial-source-code.html

Answer 1

更改密码匹配的位置，然后将md5准备添加到cpassword：

$this->form_validation->set_rules('password', 'Password', 'trim|required|md5');
$this->form_validation->set_rules('cpassword', 'Confirm Password', 'trim|required|md5|matches[password]');

Answer 2

创建帐户时，将普通密码与md5（密码）进行比较

$this->form_validation->set_rules('password', 'Password', 'trim|required|matches[cpassword]');

因此，你可以看到我们抛弃了md5的比较。我们将其添加到向数据库发送数据

'password' => md5($this->input->post('password'))

这将有助于解决这两个问题。
