How exclude children from loop with category
WordPress shows posts from all subcategories by default. This sometimes leads to mess. We will exclude these posts from the main category.
Before loop if (have_posts ()) you need to insert this code:
// Get ID of current category
$ category = get_queried_object();
$ categories = get_categories(
[‘parent’ => $category->term_id]
);
$ category = get_queried_object();
$ categories = get_categories(
[‘parent’ => $category->term_id]
);
// Collect the child category IDs of this parent:
$ children = [];
foreach ($ categories as $ k => $ v) {
$ children[] = $ v->term_id;
}
// Add new argument:
$ args = [
‘category__not_in’ => $children,
];
// Merge new arg with global query_posts
global $ wp_query;
query_posts(
array_merge(
$ wp_query->query,
$ args
)
);
And then adding original loop code:
if (have_posts()) : while (have_posts()) : the_post();
