我使用jQuery Image upload插件,像这样http://blueimp.github.com/jQuery-File-Upload/。我可以得到缩略图,并且在点击上传按钮后,我可以看到进度条,但是之后会出现“SyntaxError: JSON.parse: unexpected character”错误。请查看页面。

控制器页面:
class upload extends CI_Controller {
function __construct()
{
parent::__construct();
$this->load->helper(array('form', 'url'));
}
function index()
{
$this->load->view('index');
}
function do_upload()
{
$config['upload_path'] = './uploads/'; // server directory
$config['allowed_types'] = 'gif|jpg|png'; // by extension, will check for whether it is an image
$config['max_size'] = '1000'; // in kb
$config['max_width'] = '1024';
$config['max_height'] = '768';
$this->load->library('upload', $config);
$this->load->library('Multi_upload');
$files = $this->multi_upload->go_upload();
if ( ! $files )
{
$error = array('error' => $this->upload->display_errors());
$this->load->view('index', $error);
}
else
{
$data = array('upload_data' => $files);
$this->load->view('upload_success', $data);
}
}
}
需要帮助吗?
