Removed "Uncategorized" on WordPress Posts With Another Category
WordPress has an annoying little bug. Occasionally, when you set a category on a post, the old "Uncategorized" category will stay there. This means your post can end up with two categories: the category you just assigned, and the "Uncategorized" one.
I noticed this happens when using the bulk post editor as well. It's easy to add categories to posts in bulk, but WordPress doesn't let you remove them in bulk.
If you have dozens or hundreds of posts, this can be pretty tedious. You don't want to have to go through them one by one just to manually remove the "Uncategorized" category from all of your posts, especially when they already have another category that is properly assigned. They aren't uncategorized anymore. They have a category. Right?
Sigh.
This handy code fixes this bug. It will find all posts that belong to the "Uncategorized" category, and if they also belong to a real category, it will automatimcally remove the "Uncategorized" one.
Here's the code, add this to the bottom of your theme's functions.php file:
// For all posts with two or more categories where one of them is the default "Uncategorized" category, automatically remove the "Uncategorized" category
function remove_uncategorized_category_from_posts() {
$args = array(
'posts_per_page' => -1,
'post_type' => 'post',
'post_status' => 'any',
);
$posts = get_posts($args);
foreach ($posts as $post) {
$categories = wp_get_post_categories($post->ID);
if (count($categories) > 1) {
$uncategorized_id = get_cat_ID('Uncategorized');
if (($key = array_search($uncategorized_id, $categories)) !== false) {
unset($categories[$key]);
wp_set_post_categories($post->ID, $categories);
}
}
}
}
add_action('load-edit.php', 'remove_uncategorized_category_from_posts');Now, you can bulk assign categories to posts that are "Uncategorized", and those posts won't end up with two categories; they'll just have one.
"Uncategorized" posts are now only posts that have not been assigned another category yet. That's how it should have been from the start, right?
