parent::__construct();
$this->load->helper(array('form', 'url'));
$this->load->database();
}
public function index() {
$this->load->view('upload_form', array('error' => ' ' ));
}
public function do_upload() {
$config['upload_path'] = './uploads/';
$config['allowed_types'] = '*';
$config['max_size'] = 100;
$config['max_width'] = 1024;
$config['max_height'] = 768;
$this->load->library('upload', $config);
if ( ! $this->upload->do_upload('userfile')) {
$error = array('error' => $this->upload->display_errors());
$this->load->view('upload_form', $error);
}
else {
$data = array('upload_data' => $this->upload->data());
$this->load->view('upload_success', $data);

推荐答案
在共享主机上，您很可能需要其他方式相对路径，而不是在localhost环境中：
on a shared hosting, you most likely need a different relative path than on a localhost environment:
您可以在localhost环境中使用
you can use on a localhost environment
$config['upload_path'] = './uploads/';
但是在共享主机上，您需要提供更具体的信息，例如
but on a shared hosting, you'll need to supply more specific, something like
$config['upload_path'] = '/home/yourserver/public_html/uploads/';
您可以在左侧列的帐户cPanel主页中找到此内容，或致电您的提供商帮助台以获取更多信息正确路径上的信息
you can find this in your accounts cPanel main page on the left column or call your providers helpdesk for more info on the correct path
