Question

我有以下问题：我正在使用CodeIgniter 2.1.3，并希望上传图像并创建两个缩放图像。一个大小调整到50x50左右，一个大小调整到大约200x200。

上传工作正常。

但是当我想调整以下错误时会发生以下错误： 无法保存图像。请确保图像和文件目录是可写的。

我已将我在服务器上的权限设置为777，但仍然无法计算

这是类的代码：

public function uploadimage()
    {

         $head = array('title' => 'Upload Image');
        $error = array('error' => '');
                 $this->load->view('head',$head);
                 $this->load->view('imageUpload', $error);
                 $this->load->view('footer');
    }

    public function changeimage()
    {
          $config = array();
          $config['upload_path'] = 'img/Upload';
          $config['allowed_types'] = 'gif|jpg|jpeg|png|bmp';
          $config['max_size']   = '100';
          $config['max_width']  = '200';
          $config['max_height']  = '200';
          $config['overwrite'] = TRUE;
          $config['file_name'] = md5($this->session->userdata('username')).".png";

          $head = array('title' => 'Upload Image');
          $this->upload->initialize($config);

          if ( ! $this->upload->do_upload())
          {
                 $error = array('error' => $this->upload->display_errors());
                 $this->load->view('head',$head);
                 $this->load->view('imageUpload', $error);
                 $this->load->view('footer');
          }
          else
          {
             $uploaddata = $this->upload->data();

              //Create Thumb
              $config2 = array();
              $config2['image_library'] = 'gd';
              $config2['source_image']  = $uploaddata['full_path'];
              $config2['maintain_ratio'] = TRUE;
              $config2['width']  = 50;
              $config2['height'] = 50;
              $config2['new_image'] = '/~3612546/DateSite/img/ProfileThumbs/'.$uploaddata['file_name'];
              $this->image_lib->initialize($config2);
              if ( ! $this->image_lib->resize())
              {
                echo $this->image_lib->display_errors();
              }

              //Create resized original image so images < 200x200 get resized to get as close to 200x200
              $config3 = array();
              $config3['image_library'] = 'gd';
              $config3['source_image']  =$uploaddata['full_path'];
              $config3['maintain_ratio'] = TRUE;
              $config3['width']  = 200;
              $config3['height'] = 200;
              $config3['new_image'] = '/~3612546/DateSite/img/ProfileImages/'.$uploaddata['file_name'];
              $this->image_lib->initialize($config3);
              if ( ! $this->image_lib->resize())
              {
                  echo $uploaddata['full_path'];
                  echo $this->image_lib->display_errors();
              }

          }
    }

我真的不认为代字号对上传网址有好处：

/~3612546/DateSite/img/ProfileImages/

然后，你的所有网址都是大写/小写，将它们全部放到小写字样：

/~3612546/dateSite/img/profileimages/

最后发布了什么错误，你现在chmod 777上传文件夹，你是否只将777添加到dir或dir +他的所有内容？（这是重要的目录+他所有的内容到777）
