我想从我的数据库中删除和下载上传文件我已经上传并显示它现在我想下载并删除文件iupload 这是我的控制器showupload.php如何在codeigniter中下载和删除文件

<?php class Showupload extends CI_Controller { 

function __construct() 
{ 
    parent::__construct(); 
    $this->load->helper(array('form', 'url')); 
} 

function index() 
{ 

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


} 
public function delete_upload($file_id) { 
    $this->load->showupload('showuploadmodel'); 
    $data = $this->showuploadmodel->delete($file_id); 
    $this->load->view('showupload_view',$data); 
} 
public function download($filelink) 
{ 
$this->load->helper('download'); 
$data = file_get_contents("$filelink"); // Read the file's link 
force_download($filelink, $data);    
} 
} 
?>

，这是我的看法show_upload_view.php

<?php include_once('header.php'); ?> 
<?php include_once('tnavbar.php'); ?> 

<html> 
<head> 
<title>Show Upload</title> 
</head> 
<body> 


<div class='well'> 
<table border="0"> 
    <tr> 
    <th><h1>File Name</h1></th> 
    <th><h1>Date</h1></th> 
    <th><h1>Action</h1></th> 
    </tr> 
<?php 
foreach($query as $row){ 
echo "<tr>"; 
echo "<td><h2>". $row->filename ."</h2></td>"; 
    echo "<td><h2>". $row->date ."</h2></td>"; 
    echo "<td><h2>".Download|Delete."</h2></td>"; 
    //now how can i make download and delete from my database 
    //my database contains filename,fileid,filelink  
    echo "</tr>"; 
} 
?> 
</table> 

</div> 

</body> 
</html>

如何在ab中添加下载助手和文件助手utton ???????? – nadimsajib

如需下载，你应该使用下载助手

http://ellislab.com/codeigniter/user-guide/helpers/download_helper.html

$data = file_get_contents("/path/to/photo.jpg"); // Read the file's contents 
$name = 'myphoto.jpg'; 

force_download($name, $data);

并删除你在文件助手删除功能
