Exclude Category in WordPress

This is probably the fastest way to exclude category in WordPress besides using a plugin.

Dump this code anywhere in Theme’s template functions.php file (For example, functions.php file for a Theme named “default” would probably reside in the directory wp-content/themes/default/functions.php):

function exclude_category($query) {
	if ( $query->is_feed ) {
		$query->set('cat', '-5');  
	}
return $query;
}

add_filter('pre_get_posts', 'exclude_category');

The code example above is for excluding category ID 5 from feed.

If you want to exclude multiple categories, simply add a comma ( , ) and a dash ( - ) followed by the category ID. For example:

'-5, -6, -7'

To exclude category from main page change is_feed to is_home. Or if you want to exclude for both feed and main page, then you would need to replace:

if ( $query->is_feed ) {

with these line:

if ( $query->is_feed || $query->is_home ) {

For more possible page conditions, please refer to the Conditional Tags page in the WordPress Codex.

    Hey Zeo
    I have excluded multiple categories from my homepage. Now what I want to do is to create a navigation menu that will display all categories. Whenever I click on a button, only posts from that category should be displayed on the homepage. Is this possible?

    Thanks

  13. W/o the php tags:

    query_posts(‘cat=-1′.’&paged=’.$paged);
    // This code removes category 1.

    query_posts(‘cat=1,2,3′.’&paged=’.$paged);
    // This code shows category 1, 2 & 3.

  14. I wanted to exclude a category with working pagination. After alot of struggle I ended up posting this code before The Loop in index.php (or any other template):

    // This code removes category 1.

    Or if you want to filter from three categories:

    // This code shows category 1, 2 & 3.

  25. Excuse my lack of PHP knowledge, but…

    How do I change the “is_feed” into “is_page(’37′) ?

    I don’t see the parentesis in your “is_feed” so I don’t know how to implement it here.

    Reply

  26. Thank you, thank you, THANK YOU for this post. I spent the last three hours trying to do this for a client and could find virtually nothing on the WordPress site. I’m only a beginner when it comes to PHP, so figuring this out would have taken me hours of valuable time.

    You rock! (:

    I had the same problem as Scitt. I even tried to wrap the filter code in an if statement so it wouldn’t even appear on a category page and it still didn’t work.

    Reply

  29. Scitt

    Thanks for this. This looks like it works universally except for with category views ($query->is_category). With categories, weird things happen – With this code enabled, I see all posts from all categories regardless of which category I try to view. Looks like categories handle the query differently – like they’re not applying the pre_get_posts filter soon enough.

    hey Zeo.
    ive already excluded the categories, but the main question is how to use excluded categories in another pages ?
    i mean, if you have IT and DATA category by using the category exclude you gonna ignore them in main page, so how can we show those categories in another particular pages ?

    Thanks

  33. This helped me get closer, but let’s say I want to exclude only the most recent post from a specfic category in one feed because it’s being featured in a different section of the site? I’m trying to avoid duplicate posts on my front page while maintaining the rest of the category’s visibility. Is there any way to do this?

    For example: http://www.playerfive.com
    I have a “Featured Article” that has a listing all of it’s own. I want it to remain there, but not show up in my main feed which just lists all posts by date.

  38. Sorry – previous post was answered up above, and I missed it.

    So I’ve created a functions.php file, and it is having the effect of breaking the WP post editor! (WP 2.3.3)

    When I try to save or modify a post, a page of errors results:

    Warning: Cannot modify header information – headers already sent by (output started at /home/.goomba/calyxdesign/calyxdesign.com/wp-content/themes/modern/functions.php:15) in /home/.goomba/calyxdesign/calyxdesign.com/wp-includes/pluggable.php on line 390

    I don’t even know if the RSS feed exclusion is working, because I can’t create a post to test it.

    Any idea as to what’s happening here?

  62. RickJW

    Thought you had the answer for me there – Im running WP 2.1 and when I (finally) put the function at the start, some errors went away. But it doesnt work and at the same time it breaks the recent_posts that Im using in WP.

    I spose its back to the drawing board for me – unless I want to 1st install widgets, just for one plugin?!?! :S

    Thanks anyways! :)

    be easier to just add code to your theme functions, index.php

    php:
    if (is_home()) {
    query_posts(”cat=-5?);
    }

    I wanted to exclude several categories from the main feed (front-site feed), but the single-feed for those categories should still be available. Your function works! I’m just wondering why the single feeds are not affected by that function. Could you explain that? Thanks a lot!

    As far as I know yes. Go ahead and give it a try.

  70. Just a question, will this preserve the number of entries received? As in, does it correctly ignore the excluded category posts from the post count?
