If you’re going to use Andrew’s script, please change markdown_file_results.php to read:

<?php include_once "markdown.php";

$filename = $_GET[theFile];

if preg_match(‘[^A-Za-z0-9.-_]’, $filename) { exit (“Invalid filename supplied”); }

$fp = fopen($filename, ‘r’); $my_text = fread($fp, filesize($filename)); fclose($fp); $my_html = Markdown($my_text); ?>

The original version could allow bad people to read files they shouldn’t. This is particularly important if you’re putting this up on the internet.

Props to Andrew for putting useful code in the world and saving us from having to do it ourselves. :)
