文件上传在我的服务器上无法正常工作

问题描述：

    function upload_cover(){
        $config_cover['upload_path'] = 'img/blog/';
        $config_cover['allowed_types'] = 'gif|jpg|png|tif';
        get_instance()->load->library('upload', $config_cover);
        if($this->upload->do_upload('myFile') )
        {
            $upload_data = $this->upload->data();
            $path = 'img/blog/'.$upload_data['file_name'];
            return $path;
        }
    }
    function upload_file(){
        $config_file['upload_path'] = 'img/blog/';
        $config_file['allowed_types'] = 'doc|docx|pdf|txt|xls|xlsx|ppt|pptx';
        $this->upload->initialize($config_file);
        if ($_FILES['myDoc']) {
            if($this->upload->do_upload('myDoc'))
            {
                $upload_data = $this->upload->data();
                $path = 'document/blog/'.$upload_data['file_name'];
                return $path;
            }
        }
    }

我的电脑，但当我部署在我的服务器只有 upload_cover 工程，而不是 upload_file 。为什么？

This code is working properly on my computer but when I deploy it on my server only upload_cover works, and not upload_file. Why?

答

 function upload_file(){
        $config_file['upload_path'] = 'img/blog/';
        $config_file['allowed_types'] = 'doc|docx|pdf|txt|xls|xlsx|ppt|pptx';

        get_instance()->load->library('upload', $config_file);// try to add this
        $this->upload->initialize($config_file);
        if ($_FILES['myDoc']) {
            if($this->upload->do_upload('myDoc'))
            {
                $upload_data = $this->upload->data();
                $path = 'document/blog/'.$upload_data['file_name'];
                return $path;
            }
        }
    }
