copied!<p>All you basically need to do is to set the <a href="http://www.w3.org/Protocols/rfc2616/rfc2616-sec19.html#sec19.5.1" rel="noreferrer"><code>Content-Disposition</code></a> header to <code>attachment</code> to get a 'Save As' dialogue. Here's a kickoff PHP example:</p> <pre><code><?php header('Content-Type: application/pdf'); header('Content-Disposition: attachment;filename="foo.pdf"'); readfile('/path/to/foo.pdf'); ?> </code></pre> <p>You can't and don't want to do this with Javascript.</p> <p>Important note: due to a poor feature, in MSIE the default filename in 'Save As' dialogue won't be derived from the <code>content-disposition</code> header, it will instead be the last part of the pathinfo in the request URL. To workaround this, append the PDF filename to the link, e.g. <code>http://example.com/pdf/foo.pdf</code>. You can even make use of it in PHP to read the in the pathinfo specified PDF file. Here's a basic example of <code>pdf.php</code>:</p> <pre><code><?php $file_name = $_SERVER['PATH_INFO']; $file = '/path/to/pdf/files' . $file_name; if (file_exists($file)) { header('Content-Type: application/pdf'); header('Content-Disposition: attachment;filename="' . basename($file_name) . '"'); header('Content-Length: ' . filesize($file)); readfile($file); } else { header('HTTP/1.1 404 Not Found'); } ?> </code></pre> <p>This however assumes that you've <code>MultiViews</code> on so that <code>/pdf/</code> will go through this PHP file, or at least a <code>RewriteRule</code> from <code>/pdf/</code> to <code>/pdf.php/</code>.</p> <p>The major advantage of this approach is that you don't need to change the code whenever you want to add a new PDF file or change the PDF file name.</p> <p>You can even make it more generic by automatically determining and setting the correct content type:</p> <pre><code><?php $file_name = $_SERVER['PATH_INFO']; $file = '/path/to/all/files' . $file_name; if (file_exists($file)) { header('Content-Type: ' . mime_content_type($file_name)); header('Content-Disposition: attachment;filename="' . basename($file_name) . '"'); header('Content-Length: ' . filesize($file)); readfile($file); } else { header('HTTP/1.1 404 Not Found'); } ?> </code></pre> <p>Name it <code>files.php</code> or so and then you have a generic PHP downloader which you can access by for example <code>http://example.com/files/foo.pdf</code>, <code>http://example.com/files/bar.zip</code>, etcetera.</p> <p>Hope this helps.</p>
