推荐答案

首先，您需要检查当用户点击忘记密码时是否存在会话。
如果否，则为您将从用户处获取的电子邮件设置验证方法。

First you need to check if session exist when user click on forgot password. if No,then set validation method for email which you will be taking from user.

如下：

$this->form_validation->set_rules('email', 'Email', 'required|valid_email|callback_email_exists');

在 email_exists 方法中，检查用户是否存在或不使用给定的电子邮件ID。

In email_exists method,check if user exists or not with the given email id.

如果用户存在，则创建邮件函数。在发送重置密码的链接中。

if user exists then create a mail function.In message send link for resetting password.

$slug = md5($user->user_id . $user->email . date('Ymd'));
    $this->email->message('To reset your password please click the link below and follow the instructions:

'. site_url('forgotpassword/reset/'.$user->user_id .'/'. $slug) .'
If you did not request to reset your password then please just ignore this email and no changes will occur.
Note: This reset code will expire after '. date('j M Y') .'.');

并发送邮件。

用户点击重置链接点，该方法将再次检查session.if会话存在重定向使用到首页，否则从URL获得第三和第四段。

when user click on reset link which point the method will again check session.if session exists redirect use to Homepage else get third and fourth segment from url.

$user_id = $this->uri->segment(3);
if(!$user_id) show_error('Invalid reset code.');
$hash = $this->uri->segment(4);
if(!$hash) show_error('Invalid reset code.');

从url.again中取用户ID make $ slug 从db值，并与url $ slug .if进行比较，然后为用户提供重置字段的密码和确认密码。

Taking user id from url.again make $slug from db values and compare it with url $slug.if both matched then provide user the reset fields with password and confirm password.

如果两者都匹配，请更新密码。

If both password match.Update the password.
