I have created a custom post "company" and custom category "company category". I have a question here, I want to hide child category post in primary category.

For Example:

  • Primary Category "First"
    • Sub Category "Second"

I've created two posts "Fname" and "Sname". "Fname" was assign to First category and "Sname" assign to Second Category. I don't want show "Sname" in First category but just "Fname" be display on First category.

Is this possible?

I found a plugin solutions, Just One Category, But all of them are used for normal post type , not custom post type.

I try edit the code like this:

$q_args = array(
    'paged' => $glocal_search_pageds,
    'post_type' => array('company'),
    's' => $s,
    'company_category' => $company_category,
    'posts_per_page' => $companyprp,
    'orderby' => $orderby,
    'order' => $order,
    'tax_query' => array(
              'include_children' => false
  • It is good practice to show us the code you have tried already, working or not, or at least what you have investigated to solve the problem (more than test a plugin). – cybmeta Nov 27 '14 at 7:23

I think that the best solution is to hook into the pre_get_posts action hook. First, it is checked if we are in an archive of your custom taxonomy, then set include_children to false for the tax_query argument of the query.

add_action( 'pre_get_posts', 'cyb_pre_get_posts' );
function cyb_pre_get_posts( $query ) {
    //Assuming the slug of the custom taxonomy is company-category
    //change it with the correct value if needed
    if( $query->is_tax( 'company-category' ) && $query->is_main_query() && !is_admin() ) {
        $tax_query = array(
                'taxonomy'         => 'company-category',
                'terms'            => $query->get( 'company-category' ),
                'include_children' => false
        $query->set( 'tax_query', $tax_query );

Another approach that seems better (taken from this answer and adapted for custom taxonomy instead of core category taxonomy):

add_filter( 'parse_tax_query', 'cyb_do_not_include_children_in_company_category_archive' );
function cyb_do_not_include_children_in_company_category_archive( $query ) {
    if ( 
        ! is_admin() 
        && $query->is_main_query()
        && $query->is_tax( 'company-category' )
    ) {
        $query->tax_query->queries[0]['include_children'] = 0;

For custom queries and secondary loops (see WP_Query):

 $args = array(
             //Rest of you args go here
             'tax_query' => array(
                      'include_children' => false

 $query = new WP_Query( $args );

  • I still thinks that the answer from @ialocin is better for this job as it is filtering the current tax query. :-) – Pieter Goosen Nov 27 '14 at 7:52
  • Yes, it looks better. I didn't notice your comment. The answer of @ialocin checks foris_category(), changing that for is_tax() should work for this, as this question is for custom taxonomy. – cybmeta Nov 27 '14 at 8:02
  • Yes, it does work with is_tax(), actually had the same question a while ago. There is unfortunately not an answer as we solved this in comments. But, yes, I can confirm that it works. +1 – Pieter Goosen Nov 27 '14 at 8:08
  • yes it's work but when i search category from search mean with ?s=&company_category=firstcategory&cat=firstcategory&search_simple=search it will show all listing again .. have anyway to hide it ? – Jack Lee Nov 27 '14 at 8:41
  • That is because the code checks $query->is_tax('company-category'). That means that it is executed only for 'company-category' archives, as that is what you asked. You can add/remove more conditionals as you need. For search archives you could use $query->is_search() – cybmeta Nov 27 '14 at 10:06
