WP BBCode

Use BBCode in posts or comments. 讓你可以在部落格中使用BBCode

This plugin adds support for bbcode markup to wordpress, bbpress and buddypress. 
It integrates with the ‘bbPress shortcode whitelist’ plugin to provide a safe 
way of enabling BBCode without giving your users access to all shortcodes.

I have enhanced support for the [url] and [quote] tags, and added potentially 
useful css style class names in the html output of the tags, to allow for 
exciting theming potential.
For example:
<pre><code>[quote=NAME]QUOTE[/quote] 
</code></pre>
will render as:
<pre><code><div class="bbcode-quote bbcode-quote-NAME">NAME<blockquote>QUOTE</blockquote></div>
</code></pre>
Or if NAME matches the login name of a user on the system, it will render as:
<pre><code><div class="bbcode-quote bbcode-quote-user bbcode-quote-NAME">DISPLAY_NAME<blockquote>QUOTE</blockquote></div>
</code></pre>
Where DISPLAY_NAME is the display name that user. With BuddyPress installed the name 
also becomes a link to their profile page, otherwise if bbPress is installed, it becomes a 
link to their forum user page.

bbPress2 BBCode

This plugin adds support for popular bbcode forum code to posts, comments, pages, bbpress 2.0 forums and buddypress activity and group forums.
