想要建立像下载这样的链接吗？id = **

Question

I wanted to make download links in php.

For an example If i have 2 files in my directory then How do i make the download links like download.php?id=1 or 2 or anything.

So what will be the codes in the download.php file.

Please somebody tell me the codes.

Answer 1

use $_GET

example:

<a href="download?id=1">link</a>

<?php

$id=$_GET['id'];

if(is_numeric($id)){
$filename = 'file.pdf'; // of course find the exact filename....        
header( 'Pragma: public' ); // required
header( 'Expires: 0' );
header( 'Cache-Control: must-revalidate, post-check=0, pre-check=0' );
header( 'Cache-Control: private', false ); // required for certain browsers 
header( 'Content-Type: application/octet-stream' );

header( 'Content-Disposition: attachment; filename="'. basename($filename) . '";' );
header( 'Content-Transfer-Encoding: binary' );
header( 'Content-Length: ' . filesize( $filename ) );

readfile( $filename );

exit;

}
