圖片數據庫上傳不起作用Codeigniter

Question

我正在CodeIgniter框架上建立一個網站，以便用戶可以將網站上的產品上傳到數據庫。我試圖做一個功能，以便用戶可以上傳圖片到我的數據庫，但它並不真正工作。

這裏的一些信息： 數據庫表名：產品 我想要的圖片存儲在數據庫表的列名：product_foto 圖片文件夾：上傳

My controller: 
    <?php 
    defined('BASEPATH') OR exit('No direct script access allowed'); 
    class Product extends CI_Controller { 

    var $data = array(); 

    public function __construct() 
    { 
     parent::__construct(); 
     $this->load->model('product_model'); 
     $this->load->helper(array('form', 'url')); 
    } 

    public function product_form() 
    { 
     $save = array(
      'product_naam'   => $this->input->post('product_naam'), 
      'product_beschrijving'   => $this->input->post('product_beschrijving'), 
      'product_categorie' => $this->input->post('product_categorie'), 
      'ophaal_plaats' => $this->input->post('ophaal_plaats'), 
      'product_foto' => $this->input->post('product_foto'), 
      'date_created' => date('Y-m-d'), 
      'date_updated' => date('Y-m-d') 
      ); 

     $this->product_model->saveProduct($save); 
     redirect('https://kadokado-ferran10.c9users.io/AlleCadeausController'); 
    } 


    public function upload(){ 
     $config['upload_path'] = './upload/'; 
     $config['allowed_types'] = 'jpg|jpeg|png'; 

     $this->load->library('upload', $config); 
     if(!$this->upload->do_upload('file')){ 
     $this->db->insert('products', array(
      'product_foto' => $this->upload->file_name 
      )); 
     $error = array('error'=>$this->upload->display_errors()); 
     $this->load->view('product_form', $error); 
     }else{ 
     $file_data = $this->upload->data(); 
     $data['img'] = base_url().'/upload/'.$file_data['file_name']; 
     header('location:https://kadokado-ferran10.c9users.io/Product/'); 
     } 
    } 

    } 

我的模型文件：

<?php 
defined('BASEPATH') OR exit('No direct script access allowed'); 
class Product extends CI_Controller { 

    var $data = array(); 

我的視圖文件：

<?php echo form_open_multipart('Product/upload'); ?> 
    <input type="file" name="userfile" /> 

    <div class="form-group"> 
     <label for="name">Name</label> 
     <input type="text" name="name"> 
    </div> 

    <input type="submit" name="submit" value="test" /> 

</form> 

當我提交的圖片只被添加到上傳文件夾，但它不會加入到數據庫列的形式..

更改upload()功能跟隨其他

public function upload(){ 
    $config['upload_path'] = './upload/'; 
    $config['allowed_types'] = 'jpg|jpeg|png'; 

    $this->load->library('upload', $config); 

    if(!$this->upload->do_upload('userfile')){ 
     $error = array('error'=>$this->upload->display_errors()); 
     $this->load->view('product_form', $error); 
    }else{ 
     $file_data = $this->upload->data(); 
     $this->db->insert('products', array(
      'product_foto' => $file_data['file_name'] 
      )); 
     $data['img'] = base_url().'/upload/'.$file_data['file_name']; 
     header('location:https://kadokado-ferran10.c9users.io/Product/'); 
    } 
}
