Query mulitple categories


Query mulitple categories



So the WP codex says to query posts from different categories i use this:

query_posts('cat=2,6,17,38');

I am doing that in this (http://pastebin.com/69WTBi8Q) script to display rss feed from various categories, but it's only showing the first category in the string. http://dev.liquor.com/custom-rss-feed/

why?




Redirect referring page after login and template the profile page in wordpress

WordPress image uploader does not generate thumbnails after permalink change
Well, there are a couple of things you need to do differently.


Why should define('RELOCATE',true) be removed from wordpress config?
That code isn't outputting RSS, since you're sending the headers way too late.


Posts in Custom postype not visible on frontpage wordpress
It's rendering as text/html, not application/xml.


Giving different Post page for same type based on category or Custom Taxonomy
You can query posts telling it to make a feed:.
Wordpress Permalink hide directory name
query_posts(array(   'cat' => '2,6,17,38',   'feed' => 'rss2' )); 
To fix the category problem, try doing this:.
drag and drop the widgets
query_posts(array(   'category__in' => array(2,6,17,38),   'feed' => 'rss2' )); 
You need to hook this onto a hook any time after 'init' but no later than 'wp_loaded'..
