Question

我已经在我的网站上创建了一个登录和注册系统。我的数据库中有一个表格，其中存储了所有用户信息，称为“用户”。我搜索了很多但却无法获得太多。

我的班级

     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('');


    }


}

我的模特

     // 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;
}

}

我的表单

   <h1><p class="text-center" style="font-family: 'Passion One', 
   cursive;">Change Password</p></h1>
   <div>
   <form class="form-horizontal" method="post"

            </div>
    <br><br><br>
    </fieldset>
    </form>

    </div>

我的班级在一个名为Registration的课程内。任何帮助都会非常感激。我的模型的名称也是＆＃39; Login_Database.php＆＃39;我的表单名称是＆＃39; changepassword.php＆＃39;

请在控制器和您的型号中使用以下代码。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]);
}

我需要创建一个函数来检查旧密码并更新当前密码
