File upload not working using codeigniter. Have no idea why

我正在尝试添加一个，上传一个图像到我的根目录中。当我点击添加图像的提交按钮时，它显示if语句中的错误，就好像它是false一样。我不知道自己做错了什么。

要查看我的实时访问：http://travismichael.net/SeniorProject

我在我的根目录中有我的上传文件夹，我使它可写。

这是我的控制器

function do_upload() {
$config['upload_path'] = './uploads/';
$config['allowed_types'] = 'gif|jpg|png';
$config['max_size'] = '32';
$config['max_width']  = '200';
$config['max_height']  = '200';
$this->load->library('upload', $config);
if ( !$this->upload->do_upload('userfile'))
{
  echo  '<p>IMAGE NOT WORKING</p>';
}
else
{
  $data = array('upload_data' => $this->upload->data());
  $this->load->view('partials/upload_success', $data);
}

这是我的视图

<body>
<body class="home">

  </div>    
  <div class="navdescription"><span>Home</span></div>
</div>
  <div class="projectFolders">

某些原因Codeignator忘记更新他们的文档。

你需要在上传库的上方添加这一行

$this->upload->initialize（$config）；
