New Plugin: Close Comment Tags

October 12, 2006 – Version 1.0

The purpose of this plugin is to automatically close tags that have been left open in visitor comments. Tags that are not closed properly can sometimes cause problems – such as a strong tag left unclosed, causing the rest of the page to be in bold. The approach this plugin takes, while very simple, should work for most situations. It simply compares the number of open tags and closed tags, and adds a closing tag if needed. This plugin also takes valid code blocks into consideration. Before it processes the tags, it converts special characters to their HTML entities, so that the contents of valid code blocks are kept safe from modification.
