Codeigniter - 忘记密码

Question

您好:我需要为登录页面设置忘记密码。在这里，我解释了到目前为止我所拥有的。

恢复 View 提示收到电子邮件输入

功能 email_exists()将验证电子邮件。如果是这样，send_email()与 $temp_pass key 和链接。数据库将存储 $temp_pass 以供进一步操作和验证。

用户点击之前发送的链接，通过 $temp_pass函数reset_password。

模型 Controller 将验证 $temp_pass与数据库。如果是这样，请加载 View 以输入新密码 - 这就是我卡住的地方，因为表单指向无法识别的 Controller $temp_pass因此无法重置密码。

如何检索与正确用户关联的新密码并重置密码？

代码如下:

Controller

    public function recover(){
    //Loads the view for the recover password process.
    $this->load->view('recover');
}
public function recover_password(){
    $this->load->library('form_validation');
    $this->form_validation->set_rules('email', 'Email', 'required|trim|xss_clean|callback_validate_credentials');

            //check if email is in the database
        $this->load->model('model_users');
        if($this->model_users->email_exists()){
            //$them_pass is the varible to be sent to the user's email 
            $temp_pass = md5(uniqid());
            //send email with #temp_pass as a link
            $this->load->library('email', array('mailtype'=>'html'));
            $this->email->from('user@yahoo.com', "Site");
            $this->email->to($this->input->post('email'));
            $this->email->subject("Reset your Password");

            $message = "<p>This email has been sent as a request to reset our password</p>";
            $message .= "<p><a href='".base_url()."main/reset_password/$temp_pass'>Click here </a>if you want to reset your password,
                        if not, then ignore</p>";
            $this->email->message($message);

            if($this->email->send()){
                $this->load->model('model_users');
                if($this->model_users->temp_reset_password($temp_pass)){
                    echo "check your email for instructions, thank you";
                }
            }
            else{
                echo "email was not sent, please contact your administrator";
            }

        }else{
            echo "your email is not in our database";
        }
}
public function reset_password($temp_pass){
    $this->load->model('model_users');
    if($this->model_users->is_temp_pass_valid($temp_pass)){

        $this->load->view('reset_password');

    }else{
        echo "the key is not valid";    
    }

}
public function update_password(){
    $this->load->library('form_validation');
        $this->form_validation->set_rules('password', 'Password', 'required|trim');
        $this->form_validation->set_rules('cpassword', 'Confirm Password', 'required|trim|matches[password]');
            if($this->form_validation->run()){
            echo "passwords match"; 
            }else{
            echo "passwords do not match";  
            }
}

模型用户

    public function email_exists(){
    $email = $this->input->post('email');
    $query = $this->db->query("SELECT email, password FROM users WHERE email='$email'");    
    if($row = $query->row()){
        return TRUE;
    }else{
        return FALSE;
    }
 }
public function temp_reset_password($temp_pass){
    $data =array(
                'email' =>$this->input->post('email'),
                'reset_pass'=>$temp_pass);
                $email = $data['email'];

    if($data){
        $this->db->where('email', $email);
        $this->db->update('users', $data);  
        return TRUE;
    }else{
        return FALSE;
    }

}
public function is_temp_pass_valid($temp_pass){
    $this->db->where('reset_pass', $temp_pass);
    $query = $this->db->get('users');
    if($query->num_rows() == 1){
        return TRUE;
    }
    else return FALSE;
}

我不太确定你被困在哪里。我可以了解到您正在为用户创建一个临时标志，您在用户单击链接时验证该标志。因此，这意味着，您可以在那时开始一个 session ，并且用户只能重置密码，只有在该特定 session 处于事件状态时。

在这一步之后，你要求用户输入他的新密码，因为你有一个临时标志，你称之为 $temp_pass对于用户(请注意它应该是唯一的)，然后您可以获得尝试重置密码的用户。

所以，你需要做的就是运行这种类型的数据库查询 -

$this->db->where('reset_pass', $temp_pass);
$this->db->update('users', $data); // where $data will have the fields with values you are updating

我猜你犯了一个错误

另外，我刚刚注意到你的 recover_password()功能 -

$message .= "<p><a href='".base_url()."main/reset_password/$temp_pass'>Click here </a>if you want to reset your password, if not, then ignore</p>";

上面那行不应该是 -

$message .= "<p><a href='".base_url()."main/reset_password/".$temp_pass."'>Click here </a>if you want to reset your password, if not, then ignore</p>";

更新

您可以通过 $temp_pass进入 session 并从那里检索。这是一种方法。
