CodeIgniter多个文件上传

Question

我已经为多重上传编写了codeigniter。但是，它总是给我这个错误信息：“你没有选择要上传的文件。”

这是有问题的代码：

    $num = count($_FILES['product_image']['name']);
    for($i=0; $i<$num; $i++)
    { 
    if (!empty($_FILES['product_image']['name'][$i])) 
    {
    $_FILES['product_image']['name']= $_FILES['product_image']['name'][$i];
    $_FILES['product_image']['type']= $_FILES['product_image']['type'][$i];
    $_FILES['product_image']['tmp_name']= $_FILES['product_image']['tmp_name'][$i];
    $_FILES['product_image']['error']= $_FILES['product_image']['error'][$i];
    $_FILES['product_image']['size']= $_FILES['product_image']['size'][$i];     

    $this->upload->do_upload('product_image');

    $this->data['message'] = $this->upload->display_errors();
    }          
    }
