推荐答案

尝试这样，

function upload_files()
{       
    $config = array();
    $config['upload_path'] = './Images/';
    $config['allowed_types'] = 'gif|jpg|png';
    $config['max_size']      = '0';
    $config['overwrite']     = FALSE;

    $this->load->library('upload');

    $files = $_FILES;
    for($i=0; $i< count($_FILES['userfile']['name']); $i++)
    {           
        $_FILES['userfile']['name']= $files['userfile']['name'][$i];
        $_FILES['userfile']['type']= $files['userfile']['type'][$i];
        $_FILES['userfile']['tmp_name']= $files['userfile']['tmp_name'][$i];
        $_FILES['userfile']['error']= $files['userfile']['error'][$i];
        $_FILES['userfile']['size']= $files['userfile']['size'][$i];    

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