Used the code:
function exclude_category($query) {
if ( $query->is_home ) {
$query->set('cat', '-147');
}
return $query;
}
add_filter('pre_get_posts', 'exclude_category');to exclude posts from a category from showing up on the front page, but since I updated WordPress to 3.1 it doesn't work anymore.
EDIT: Also noticed that the URL of categories has changed from "http://www.example.com/?cat=xx" to "http://www.example.com/?category_name=NAMEOFCAT"
How do I fix this?

not sure if its related, are you using the 'Simple Tags' plugin?
Its gone haywire for me on 3.1, and ruined most of my category related queries
Posted 1 year ago #
No, not using 'Simple Tags'. Hasn't really gone haywire just yet, but nonetheless I'm regretting clicking the "Automatically Update" button.
I have this problem too. I didn't expect things to break -- but I also regret not upgrading the test version of my website first before upgrading production.
Anyway, a solution to this problem would help a lot. Thanks!

I have the same issue. lot's of posts showing up on main page that shouldn't be there.

@greenflag: Yeah been messing around trying to get it to work but nothing so far. Do tell me if you find something, would really help.
Posted 1 year ago #
nothing on my end. i searched for answers and this is so new there is no info on it yet...
Posted 1 year ago #
i do have other edits (like limit # of posts on main page) that are working just fine. it only seems to be this one...
Posted 1 year ago #
@greenflag: Yeah all of that works, in fact the "Functions.php" was not overwritten in the update (I had it write protected before hand). It's just the "exclude_category" function that doesn't work right.
Did you notice the change in the URL format (For Categories) as well?
Posted 1 year ago #
i didn't notice categories change, no. i use a plugin that removes /category/ from the url.

seems you have stumbled onto a bug, which has been reported

Too bad, meaning for now there's no way to fix this yeah?
Well, guess I could survive for a couple of days.
Try using category__not_in instead of cat.
function exclude_category($query) {
if ( $query->is_home ) {
$query->set('category__not_in', '147');
}
return $query;
}
add_filter('pre_get_posts', 'exclude_category');

@Otto; Thanks, that actually works. So why exactly does this work?
Because of a bug in the "cat" parameter that is not in the "category__not_in" parameter.

But does this work for various categories or just one?
Posted 1 year ago #
I'm using it for just one category, but I don't see why it wouldn't work for many. Just separate the category numbers by a space.
Posted 1 year ago #
i try it for like 7 categories and doesn't work but :(
Posted 1 year ago #
Unless you're using the latest version of WordPress try putting a - before the category number
Posted 1 year ago #
Yes i found the same thing - it only works with 1 category.
Posted 1 year ago #
So I guess you're using an older version of WordPress?, I'm currently using 3.1 and I don't need the -.
Posted 1 year ago #
i'm using 3.1. the way of doing it mentioned in 1st post here allowed for multiple cat exclusion like this:
-1 -2 -3 -4 etc
the way otto suggests seems to work for only for 1 category - meaning:
1 2 3 4 wont work
Posted 1 year ago #
Yeah it only works for one category
Posted 1 year ago #
This plugin is working!!! click here

If you want to fix it for multiple categories on your own without using a plugin you can change your exclude function to something like this:
function exclude_category($query) {
$exclude_categories=array('-1','-2','-3','-4');
if ( $query->is_home ) {
$query->set('category__not_in', $exclude_categories);
}
return $query;
}
add_filter('pre_get_posts', 'exclude_category');
NOTE: use your own category number in the $exclude_categories array.
NOTE 2: I've noticed that using positive numbers for categories works just as well.

BRILLIANT FIX
function exclude_category($query) {
if ( $query->is_home ) {
$query->set('category__not_in', '147');
}
return $query;
}
add_filter('pre_get_posts', 'exclude_category'):Thanks @otto! I wasted about 3 hours trying things this morning before it occurred to me this might be a 3.1 bug... and your function totally fixed my problem in 5 seconds.
have made a note, too, @mmorpglife of your multi-category fix.
thankful there are people like you who can think in code, cuz i surely cannot. :D
