Question

我做了一个编辑/更新功能，效果很好。我试图允许用户提交编辑，而不必上载或更改数据库中的图像，因为单击“编辑”时不会再次加载原始图像。因此，当您不再加载图像时，它将引发错误。

我已经尝试了一些方法，但是如果有人可以给我一些提示或指点，那么这个问题仍然存在，因为我对共同创始人有点新意。

控制器：

public function edit($slug){

  if($this->session->userdata('customer_id') !=$this->post_model->get_posts($slug)['customer_id']){

    redirect('users/login');
  }


  if(!$this->session->userdata('logged_in')){

    $this->session->set_flashdata('log_post','Please login or create a free account to post a ad.');

    redirect('users/login');
  }

    ////Checks the user


  $data['categories'] = $this->post_model->get_categories();

  $data['post_image'] = $this->post_model->get_posts('post_image');

  $data['post'] = $this->post_model->get_posts($slug);

  if(empty($data['post'])){
    show_404();
  }

$data['title'] = 'Edit Your Post';

$this->load->view('templates/header');
$this->load->view('posts/edit', $data);
$this->load->view('templates/footer');


}


public function update(){



  if(!$this->session->userdata('logged_in')){

    $this->session->set_flashdata('log_post','Please login');

    redirect('users/login');

}

else {


  if($_FILES['userfile']['name'] != "")
  {
     if($_FILES['userfile']['type'] == 'image/jpeg'){
      $ext = ".jpeg";
    }
      if($_FILES['userfile']['type'] == 'image/jpg'){
       $ext = ".jpg";
     }
      else if($_FILES['userfile']['type'] == 'image/png'){
      $ext = ".png";
    }
}

    $imageedit = time();

            $config = array(
              'file_name' => $imageedit,
              'upload_path' => "assets/images/posts/",
              'allowed_types' => "jpg|png|jpeg",
            );

    $this->upload->initialize($config);

    if(!$this->upload->do_upload('userfile')){

          $this->session->set_flashdata( 'error_msg', $this->upload->display_errors());
               redirect('posts/edit');
             }

             else {

      $this->post_model->update_post($imageedit,$slug);


    }
elseif {

$orginal = $this->post_model->orignal_image();

}


  $this->post_model->update_post($imageedit,$slug,$orginal);

  $this->session->set_flashdata('post_updated', 'Your post has been updated');


  redirect('posts');
}
}

  }//ending bracket

型号：

Public function update_post($imageedit,$slug,$orignal){


  $site = $this->input->post('site');


      if (!preg_match("~^(?:f|ht)tps?://~i", $site)) {
          $site = "http://" . $site;
      }



  $data = array(

  'title'=>$this->input->post('title'),
  'body'=> $this->input->post('Description'),
  'category_id' => $this->input->post('category'),
  'post_image' => $imageedit || $orginal,
  'customer_id' =>$this->session->userdata('customer_id'),
  'site'=>$site


  );
  $this->db->where('id',$this->input->post('id'));
  return $this->db->update('posts',$data);
}


public function user_posts() {

        $this->db->order_by('created_time', 'DESC');
        $query = $this->db->get_where('posts', array('customer_id' => $this->session->userdata('customer_id')));
        if ($query->num_rows() > 0) {
            return $query->result_array();
        } else {
            return false;
        }
    }


public function orginal_image($slug=NULL,$orginal){
$this->db->select('post_image');
$this->db->from('posts');
$query = $this->db->get_where('posts',array('slug'=>$slug));
  return $query->row_array();
}

}

查看代码：

<input type ="hidden" id="orginal" name="orginal" value = <?php echo $orginal; ?>
