Question

我创建了具有正确验证的注册表格，并将其插入数据库中。现在我正在尝试更新记录，但我不知道为什么我的记录没有得到更新。请任何人让我知道我的记录未更新可能是什么问题。请从早上开始尝试，但无法获得理想的结果。即使验证也不起作用。请任何人查看我的代码，然后告诉我。

From.php（控制器）

        public function updatedata()
        {
        $id=$this->input->get('id');
        $result['data']=$this->Form_model->displayrecordsById($id);
        $this->load->view('update_records',$result);    

            if($this->input->post('update'))
            {
                $this->form_validation->set_rules('fname', 'First name', 'required');
                $this->form_validation->set_rules('lname', 'Last name', 'required');
                $this->form_validation->set_rules('username', 'Username', 'required|min_length[5]|max_length[12]|is_unique[form.username]');
                $this->form_validation->set_rules('email', 'Email', 'required|valid_email|is_unique[form.email]');

                if ($this->form_validation->run() == TRUE)
                {

                    $config['upload_path']   = './uploads/'; 
                    $config['allowed_types'] = 'gif|jpg|png'; 
                    $this->load->library('upload', $config);

                    if($this->upload->do_upload('filename'))
                    {
                        $fn=$this->input->post('fname');
                        $ln=$this->input->post('lname');
                        $un=$this->input->post('username');
                        $em=$this->input->post('email');
                        $fi = $this->upload->data('file_name');
                        $this->Form_model->updaterecords($fn,$ln,$un,$em,$fi,$id);
                        echo 'Successfully updated your record';
                    }
                }
            }
        }
