Does anybody know how I can display a different "blogroll" (or different backlinks) based on category selected in wordpress?
There a WP Plugin for that Hope this can help you http://0xtc.com/2009/04/22/wp-render-blogroll-links-plugin.xhtml
and if you want to have manual control and write code, you can use wordpress template tags for specifying different content in different category, write in template file something like <?php if (in_category('first')) { ?> BLOGROLL DISPLAY CODE HERE <?php } else if (in_category('second')) { ?> ANOTHER BLOGROLL DISPLAY CODE HERE <?php } else { ?> DISPLAY OTHER BLOGROLL CODE HERE <?php } ?> "first" and "second" are slug names of categories
