Question

Kohana

Hello.
Those who know php and frameworks, tell me how to upload 2 or more photos.
I think the essence does not have any framework, but in general ko7, kohana.

My action for uploading and displaying all uploaded photos in the template.

public function action_index()
    {

    $id = (int)$this->request->param('id');

    $fotogalerejas = ORM::factory('Fotogalereja')
      ->order_by('id', 'DESC')
      ->find_all();

    if (isset($_POST['submit']))
    {

      $fotogalerejas = ORM::factory('Fotogalereja');

        try
            {

        $fotogalerejas->save();
        $id = $fotogalerejas->pk();

                if (!empty($_FILES['images']['name'][0]))
                {
                    foreach ($_FILES['images']['tmp_name'] as $i => $image)
                    {
                        $filename = $this->_upload_img($image);
                        $im_db = ORM::factory('Image');
                        $im_db->fotogalereja_id = $fotogalerejas->pk();
                        if (!empty($filename))
                        {
                            $im_db->image = $filename;
                            $im_db->save();
                        }
                        $p_db = ORM::factory('Fotogalereja', $fotogalerejas->pk());
                        if ($p_db->image_id == 0) {
                        $p_db->image_id = $im_db->pk();
                        $p_db->save();
                        }
                    }
                }

              $this->redirect('admin/fotogalereja/');
            }
            catch (ORM_Validation_Exception $e)
            {
            $errors = $e->errors('validation');
            }
    }

      $content = View::factory('admin/fotogalereja/index')
      ->bind('errors', $errors)
      ->bind('id', $id)
      ->bind('fotogalerejas', $fotogalerejas);

        $this->template->page_title = 'Фотогалерея';
        $this->template->content = $content;
    }

At the moment the code works, the photo is loaded, but it loads 1 photo, although I choose 2 or more.

What do I see in the database. (this is if I select several photos to upload, but it loads one).


If I try to upload another photo, then each photo has its own id, I don’t know if it’s correct, I think there is no difference, one id or different ones, which I see in the database.
