Downloading file (Headers)

Posted on 16th Feb 2014 07:03 pm by admin

I'm trying to make users download a file, but they must wait 60 seconds before it begins.

But, I'm stuck - the file isn't downloading, and no error is being shown (I've enabled E_ALL error reporting).

The file does exist.

Here is the code I use to download the file (I've cut the code that isn't needed)
Code: (php) [Select]<?php
//code removed
case "dlStart":
$file = $_POST['fileid'];
//query
$query = "SELECT * FROM files WHERE fid=$file";
$result = $sql->query($query);
$row = $result->fetch_assoc();
$file = $row['filelocation'];
if ($result->num_rows != 1){
$content = '<h1>Download File</h1>
<h2>Looks like you&#39;ve found an error!</h2>
<p>The file that you are trying to download either has been deleted, or has never existed.</p>
<p>Please go back and try again.</p>';
$content .= '<p style="text-align: center; ">Powered by <a href="http://www.scriptboxer.com/download-site-script.php">DownloadBoxer v1</a>.<br />

$html = str_replace('{content}', $content, $html);
$html = str_replace('{title}', 'Downloading File....', $html);
echo $html;
}else{
$content = '<form name="counter"><h1>Download File</h1>
<h2>Your download will begin in:
<input name="d2" size="1" type="text" style="font-family:Segoe UI, Trebuchet MS, Helvetica, sans-serif; font-size:23px; font-weight:bold;" /> seconds</h2>
</form>

<p><strong>Why do I have to wait to download my file?</strong><br />
We require users to wait before downloading files, so that we can reduce the load on the server. Sometimes, you will be able to download immediately,
other times you will need to wait upto 20 minutes.</p>

echo $html;
break;
?>
The files are located outwith the public directory, and the MySQL db has the full location stored in it (as the format /home/bleh/blah/etc)

Can anyone help?

I'd also like the download to begin after $config['waittime'], so how do I do that aswell?
