I've created a downloads folder in root, into which I uploaded a file. On my web page I created a link to the file. When I click the link on the published web page, it shifts me to the opened file (instead of downloading to where I usually send downloads).

I tried zipping the file, which works, but I'm on a Mac and PCers tell me a zip file from Mac includes 'other' things with the zipped file which I don't understand, but would instead like to know if there is a simpler way to do this.

So, how do I store the file so that web users can click on download and actually have the file downloaded to their computer instead of opening in a browser page?

Thanks

Hello bosso,

To force the browser to download a file instead of displaying in the browser, you will want to do two a couple of things:

1) log into your cpanel and enter the File Manager.

2) Create or upload a new, blank file named .htaccess (note the . in the front, that is necessary)

3) Place a line of code similar to the following for each type of document you want to force a download. In the examples below, I gave three different file types, .mov, .pdf, and .txt

AddType application/octet-stream .mov
AddType application/octet-stream .pdf
AddType application/octet-stream .txt

This should force your visitors browsers to download the file type for those extensions in that folder.

I hope this answers your question. If you have any more questions or information specific to the issue please leave a comment below so we can further assist you.

Best Regards,

Hello Eldewiny,

What in particular are you attempting to accomplish with the file types? Are you attempting to handle them differently within your script for each?

Thank you frist for your answer and here is the code what i use

<?php

function download($file){
$dir = './download/';
$path = $dir.$file;
if(!file_exists($path)){
die('Error');
}else{
header('Content-Description : File Transfer');
header('Content-Disposition : attachment; filename='.basename($path));
header('Content-Type: application/octet-stream');
header('Expires: 0');
header('Cache-Control: must-revalidate');
header('Pragma: public');
header('Content-Length: ' . filesize($file));
ob_clean();
ob_start();
flush();
readfile($path);
exit;
}
}
if (isset($_GET['download'])) {
if (!empty($_GET['download'])) {
$file = $_GET['download'];
download($file);
}
}
?>

<a class="download-template" href="example.php?download=modern.rar">Download</a>

The error was being caused by extra spaces within your header lines. Rewriting it to the following works just fine:


<?php
function download($file){
$dir = './download/';
$path = $dir.$file;
if(!file_exists($path)){
die('Error');
}else{
header('Content-Description: File Transfer');
header('Content-Disposition: attachment; filename='.basename($path));
header('Content-Type: application/octet-stream');

header('Expires: 0');
header('Cache-Control: must-revalidate');
header('Pragma: public');
header('Content-Length: ' . filesize($file));
ob_clean();
ob_start();
flush();
readfile($path);
exit;
}
}
if (isset($_GET['download'])) {
if (!empty($_GET['download'])) {
$file = $_GET['download'];
download($file);
}
}
?>

These errors were being caused by the order in which your PHP includes were defined. As your header PHP include file was defined before the download script PHP include, the download script was unable to set the header information that is defined within it. I have reversed the two lines on your page so that the download script is called first, and as I see you have adjusted your previous code with that I provided previously, it appears to be working now.

It has been my pleasure. One thing I would like to add is to avoid using GET requests to defined the file to be downloaded. This could be exploited to read from any file on your site and could cause your site to become hacked. I recommend directly linking to the file for download instead.
