SimpleSmileyShow is a plugin that takes whatever smilies are currently defined and displays them in a row just before the comment textarea on any page with comments. Clicking on the smilies will insert the code for that smiley into the textarea at the position of the cursor. No configuration is required.
The smilies can be adjusted with CSS; each clickable smiley has the class wp-smileylink and the block containing them has the ID wp-smileyblock.
This plugin is designed to work with the WordPress 3 style of comment pages which use comment_form() and have the actions comment_form_after_fields, comment_form_logged_in_after, and comment_form_must_log_in_after present. (This should be the majority of modern themes.) This plugin does not work with the Jetpack plugin if the new comment system is enabled, since it replaces the normal comment_form() completely.
This plugin uses JQuery and the jquery.insertatcaret plugin. It has been tested tested with the twentyten through twentyfourteen themes.
Development on this plugin has halted. Other developers should feel free to use the Apache-licensed code for their own projects.
