I'm looking to show the tags of a post within a widget. I know this is hard because it's outside of the loop, but has it been done, is there one available?
Thanks for any assistance.
Tags can be shown outside the Post loop using the global functions.
Step 1 : Get a PHP Code Widget (this solved many problems)
Step 2 : Place the Code
Check Tags Documentation to tweak display order.
All done just rock and roll.
Its not very hard actually, wordpress supports multiple loops and query's.
The best way to create a secondary (or more) loop is to make an instance of WP Query, http://codex.wordpress.org/Class_Reference/WP_Query
Using that you can make a simple query that gets the posts tags using
Then you would throw the code into a widget, http://codex.wordpress.org/Widgets_API.
I believe this plugin does exactly what you're looking for: http://wordpress.org/extend/plugins/nktagcloud/
Hope this helps! Michelle
