Create a link that will start a download

I am relatively new to web design and I was wondering how you create a link that will initiate a download like the ones you find on software download sites. I have tried to look at the code from one to figure it out, but had no luck.

This is the code I tried to break down:
<a href="(URL address blocked: See forum rules)=10672637&merid=61683&mfgid=61683&ltype=dl_dlnow&lop=link&edId=3&siteId=4&oId=3040-2646_4-10672637&ontId=2646_4&destUrl=(URL address blocked: See forum rules)" onClick="return rbdl.dlNow('(URL address blocked: See forum rules)=link&ptype=3000&ontid=2646&siteId=4&edId=3&pid=10672637&psid=10041527','(URL address blocked: See forum rules)=10672637&merid=61683&mfgid=61683&ltype=dl_dlnow&lop=link&edId=3&siteId=4&oId=3040-2646_4-10672637&ontId=2646_4&destUrl=(URL address blocked: See forum rules))" class="download" onMouseOver="document.dln.src='(URL address blocked: See forum rules)" onMouseOut="document.dln.src='(URL address blocked: See forum rules)">

PHP Code:


		
			
<?php

        $filename = $_SERVER["DOCUMENT_ROOT"] . '/downloads/' . eregi_replace("[^a-zA-Z0-9\\._-]", "", $_GET['filename']);

        // required for IE, otherwise Content-disposition is ignored

        if(ini_get('zlib.output_compression')) {

        ini_set('zlib.output_compression', 'Off');

        }

        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: image/jpg");

        header("Content-Disposition: attachment; filename=" . basename($filename) . ";" );

        header("Content-Transfer-Encoding: binary");

        header("Content-Length: " . filesize($filename));

        readfile($filename);

?>

If you send the file name to this file (put this code in dl.php, i.e.), via GET or POST (if you use POST, change this file accordingly). The regex makes sure only these: a-zA-Z0-9._- are valid characters and strips the rest. No spaces or text before <?php.

Example: <a href="dl.php?filename=movie.avi">download me!</a>

This should work a treat.

Ooor <a href="download.exe">Download</a>. That will pop up a download box and not redirect to any other page than the link. That link you were looking at is probably for security.

You don't need anything other than html for download links..

BTW, WHY did i get an email from this website even though i clicked NOT to? that's called spam and i think it's illigal.
