WooCommerce - Exclude products from child categories

functions.php

<?php
function exclude_product_cat_children($wp_query) {
	if ( isset ( $wp_query->query_vars['product_cat'] ) && $wp_query->is_main_query()) {
    	$wp_query->set('tax_query', array(
            array (
                'taxonomy' => 'product_cat',
                'field' => 'slug',
                'terms' => $wp_query->query_vars['product_cat'],
                'include_children' => false
            )
		) );
  	}
}

add_filter('pre_get_posts', 'exclude_product_cat_children', PHP_INT_MAX );

This code works fine, but it breaks admin products search in backend. :/

same problem. any help?

You can additional conditional tags to make sure the filter is applied only on frontend get_posts and not backend posts.

hi! i corrected as @ibndawood say adding a conditional tag. like this:

`<?php
function exclude_product_cat_children($wp_query) {
if ( is_product_category() ) {
if ( isset ( $wp_query->query_vars['product_cat'] ) && $wp_query->is_main_query()) {
$wp_query->set('tax_query', array(
array (
'taxonomy' => 'product_cat',
'field' => 'slug',
'terms' => $wp_query->query_vars['product_cat'],
'include_children' => false
)
) );
}
} }

add_filter('pre_get_posts', 'exclude_product_cat_children', PHP_INT_MAX );`
