Simple WordPress plugin for up/down voting on posts and comments.

UpDownUpDown provides two template tags for adding up/down voting for any post or comment. Anonymous guest visitors can either be allowed to vote (tracked by ip address) or be denied voting and shown a view-only vote count badge. Votes are registered on the server without refreshing the page.

This plugin was initially developed as a project of Wharton Research Data Services.

1. Upload the folder containing the plugin to the /wp-content/plugins/ directory
2. Activate the plugin through the 'Plugins' menu in WordPress
3. Place the following function calls in your templates, somewhere inside the post or comment loop:
4. <?php if(function_exists('up_down_post_votes')) { up_down_post_votes( get_the_ID() ); } ?>
5. <?php if(function_exists('up_down_comment_votes')) { up_down_comment_votes( get_comment_ID() ); } ?>
6. Display vote badge display only with no voting by setting the second parameter to false:
7. <?php if(function_exists('up_down_post_votes')) { up_down_post_votes( get_the_ID(), false ); } ?>
8. <?php if(function_exists('up_down_comment_votes')) { up_down_comment_votes( get_comment_ID(), false ); } ?>
9. Visit the plugin settings page to customize it.

1. This shows a badge in a post with no votes yet.
2. This shows a badge in a post with a vote set.
3. This shows a view-only badge if voting is disabled via theme function flag or guest voting is disabled in the admin settings.
4. This shows a badge using the alternate simple style.
5. Admin settings page for the plugin.
