By scribuRandom Post Link Plugin
Generates a link that takes a visitor to a random post, but never the same as before.
Unlike the Random Redirect plugin, this plugin makes sure that a user will not see the same post twice.
It does this by storing a cookie containing a list of single posts that the user has seen. It then checks that list before redirecting.
Usage
Just put this line anywhere in your theme where you want the link to appear.
<?php random_post_link(); ?> You can specify the text you want on the link like so:
<?php random_post_link('Feeling lucky'); ?> Links: Plugin News | Author’s Site
FAQ
“Parse error: syntax error, unexpected T_CLASS…” Help!
Make sure your host is running PHP 5. Add this line to wp-config.php to check:
var_dump(PHP_VERSION); What happens when there are no more posts?
If a user has seen all the available posts, the plugin will clear the list and redirect to a random post.
