INSTRUCTIONS
1. Copy this file into the plugins directory in your WordPress installation
(wp-content/plugins).
2. Log in to WordPress administration. Go to the Plugins page and Activate
this plugin.
Once you've activated the plugin, you can get a random post link by calling the
fla_random_post() function. The function can be called one of two ways:
1. <?php fla_random_post("link text"); ?>
This generates and prints an entire URL to a random published post in the
following format:
<a href="http://link_to_random_post">link text</a>
The displayed URL, including the anchor tags and link text as shown above,
is also returned as the function's value.
2. <?php fla_random_post(); ?>
This generates a URL to a random published post in your blog, and returns
a fully qualified URL to you for you to use. It displays nothing.
