如何在codeigniter的按钮中添加下载助手

Question

我想在表中添加一个链接，该链接下载并删除我上传的数据codeigniter。这是我的浏览器，它只能说明从我上传的数据库文件名和日期

foreach($query as $row) 
{ 
    echo "<tr>"; 
    echo "<td><h2>". $row->filename ."</h2></td>"; 
    echo "<td><h2>". $row->date ."</h2></td>"; 
    echo "<td><h2>".$row->filelink."</h2></td>"; 
    //now how can i make download and delete from my database 
    //my database contains filename,fileid,filelink  
    echo "</tr>"; 
} 

我的模型是

function showfile() 
{ 
    $this->db->select('filename, filelink, date'); 
    $query = $this->db->get('upload_file'); 
    return $query->result(); 
} 

我控制器

function index() 
{ 
    $this->load->model('showuploadmodel'); 
    $data['query']=$this->showuploadmodel->showfile(); 
    $this->load->view('showupload_view',$data); 
} 

我要添加删除链接并下载链接，并从数据库中仅删除特定行并下载为其传递标识的文件。我如何将数据库中的字段传递给下载助手？调用下载助手，而不是控制器

通场本身downloadhelper

试试这个

foreach($query as $row) 
{ 
    echo "<tr>"; 
    echo "<td><h2>". $row->filename ."</h2></td>"; 
    echo "<td><h2>". $row->date ."</h2></td>"; 
    echo "<td><h2>".$row->filelink."</h2></td>"; 
    echo "<td><h2><a href='".site_url('path/to/controllers/download/'.$row->id)."'>Download</a></h2></td>"; 
    echo "<td><h2><a href='".site_url('path/to/controllers/delete/'.$row->id)."'>Delete</a></h2></td>"; 
    echo "</tr>"; 
} 

和控制器添加相关功能

function download($id){ 
     //$id is that particular Id 
     //do stuff with download helper 
} 

function delete($id){ 
     //$id is that particular Id 
     //delete code 
}
