codeigniter从数据库下载

问题描述

我根据已插入数据库的文件名下载pdf下载函数，这是我的功能：

I make a download function to download pdf based on filename that has already inserted on database and this is my function:

function download($offset=0,$order_column='judul',$order_type='asc'){
        $this->load->helper('download');
        if(empty($offset)) $offset=0;
        if(empty($order_column)) $order_column='judul';
        if(empty($order_type)) $order_type='asc';

        //load data
        $data=$this->m_ebook->semua($this->limit,$offset,$order_column,$order_type)->result();



        $config['total_rows']=$this->m_ebook->jumlah();
        $config['per_page']=$this->limit;
        $config['uri_segment']=3;
        $this->pagination->initialize($config);
        $data['pagination']=$this->pagination->create_links();
        foreach ($data as $row)
        {
            $data=file_get_contents("./assets/files/".$row->file);
            $name = 'download.pdf';

            force_download($name,$data);
        }

    }

这些是我的型号：

these are my models:

function semua($limit=10,$offset=0,$order_column='',$order_type='asc'){
        // $db1 = $this->load->database('default',TRUE);

        if(empty($order_column) || empty($order_type))
            $this->db->order_by($this->primary,'asc');
        else
            $this->db->order_by($order_column,$order_type);
        return $this->db->get($this->table,$limit,$offset);
    }

function jumlah(){
        return $this->db->count_all($this->table);
    }

问题是我下载的文件始终是数据库中的第一个pdf名称

你可以帮我修改我的代码吗？

the problem is the file that I downloaded is always the first pdf name from database
can you help me fix my code?
