我想从我的数据库中删除并下载上传文件我已经上传并显示它现在我想下载并删除iupload的文件这是我的控制器showupload.php

<?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);            
}
}
?>

这是我的观点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>

现在如何从我的数据库中下载和删除我的数据库包含filename，fileid，filelink

Answer 1

要下载，您应该使用Download Helper

https://www.codeigniter.com/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);

为了删除你在File Helper中有删除功能

delete_files('./path/to/directory/');
