我需要创建一个函数来检查旧密码并更新当前密码

Question

我已经在我的网站上创建了一个登录和注册系统。我在我的数据库中有一张表，其中存储了所有用户信息，称为“用户”。我查了很多，但无法获得太多。

我班

 public function change_password() 
{ 

    $this->load->view('templates/header'); 
    $this->load->view('registration/changepassword'); 
    $this->load->view('templates/footer'); 
} 

public function change() 
{ 
    $this->form_validation->set_rules('newpassword', 'New Password', 'required|matches[rpassword]'); 
    $this->form_validation->set_rules('rpassword', 'Retype Password', 'required'); 

    if ($this->form_validation->run() == FALSE) { 
     redirect('registration/change_password'); 
    }else{ 
     $query = $this->Login_Database->checkOldPass(sha1($this->input->post('oldpassword'))); 
     if($query){ 
      $query = $this->Login_Database->saveNewPass(sha1($this->input->post('newpassword'))); 
      if($query){ 
       redirect('registration/change_password'); 
      }else{ 
       redirect('registration/change_password'); 
      } 
     } 
     redirect(''); 


    } 


} 

我的模型

 // Insert registration data in database 
public function checkOldPass($old_password) 
{ 

    $this->db->select('*'); 

    $this->db->from('users'); 
    $this->db->select('id'); 
    $this->db->where('id', 'id'); 
    $this->db->where('password', $this->input->post('oldpassword')); 
    $query = $this->db->get(); 
    if ($query->num_rows > 0) { 
     return true; 
    } else { 
     $this->form_validation->set_message('checkOldPassword', 'wrong old password.'); 
     return false; 
    } 
} 

public function saveNewPass($new_pass) 
{ 
    $data = array(
     'password' => $new_pass 
    ); 
    $this->db->where('id', 'id'); 
    $this->db->update('users', $data); 
    return true; 
} 

}

我的形式

<h1><p class="text-center" style="font-family: 'Passion One', 
    cursive;">Change Password</p></h1> 
    <div> 
    <form class="form-horizontal" method="post" 
     action="<?php echo base_url() ?>Registration/change"> 
    <fieldset> 
     <br> 
     <div class="form-group"> 
      <label class="col-md-4 control-label" for="phone">Old 
    Password</label> 
      <div class="col-md-4"> 
       <input id="oldpassword" name="oldpassword" type="password" 
    placeholder="Old Password" 
         class="form-control input-md" 
         required=""> 
      </div> 
     </div> 
     <div class="form-group"> 
      <label class="col-md-4 control-label" for="phone">New 
     Password</label> 
      <div class="col-md-4"> 
       <input id="newpassword" name="newpassword" type="password" 
     placeholder="New Password" 
         class="form-control input-md" 
         required=""> 
      </div> 
     </div> 
     <div class="form-group"> 
      <label class="col-md-4 control-label" for="phone">Conform 
     Password</label> 
      <div class="col-md-4"> 
       <input id="rpassword" name="rpassword" type="password" 
     placeholder="Retype Password" 
         class="form-control input-md" 
         required=""> 
      </div> 
     </div> 
     <br> 
     <!-- Button (Double) --> 
     <div class="form-group"> 
      <label class="col-md-4 control-label" for="save"></label> 
      <div class="col-md-8"> 
       <button type="submit" class="btn btn-success">Save</button> 
       <a id="cancel" name="cancel" class="btn btn-danger" href="<? 
    php echo base_url(); ?>"> 
        Cancel</a><br><br> 
      </div> 
    <br><br><br> 
    </fieldset> 
    </form> 

    </div> 

我的课是在名为Registration.Any帮助将不胜感激。此外，我的模型的名称是'Login_Database.php'，我的表单的名称是'changepassword.php'

请在控制器和您的模型中使用以下代码。如果您有任何问题，请回复我。

//控制器功能

public function change(){ 
    if ($this->form_validation->run('update_password') == True) 
    { 
     $old_password = sha1($_POST['oldpassword']); 
     unset($_POST['oldpassword']); 
     $post = $this->input->post(); 
     $status = $this->model_name->check_old_password($old_password, $user_id); //check old password 
     if($status==true){ 

      if($_POST['newpassword']==$_POST['rpassword']){ 

       if($this->model_name->update_password($post, $user_id)){ 
        $this->session->set_flashdata('message_success', "Password update successully."); 
        redirect('registration/change_password'); 
       }else{ 
        $this->session->set_flashdata('article_failed', "Password not update successully."); 
        redirect('registration/change_password'); 
       } 

      }else{ 
       $this->session->set_flashdata('article_failed', "Sorry your new password and confirm password does not matched."); 
       redirect('registration/change_password'); 
      } 

     } 
    }else{ 
     $this->session->set_flashdata('article_failed', "Sorry your old password is wrong."); 
     redirect('registration/change_password'); 
    } 
} 

// model function 
public function check_old_password($old_password, $user_id){ 
    $query = $this->db->select('id') 
         ->from('users') 
         ->where(['id'=>$user_id, 'password'=>$old_password]) 
         ->get() 
         ->row(); 

     if($query>0){ 
      return TURE; 
     }else{ 
      return FALSE; 
     } 
} 

public function update_password($post, $user_id){ 
    $password = sh1($post['newpassword']); 
    return $this->db->where('id', $user_id) 
        ->update('users', ['password'=>$password]); 
}
