Exclude Product Categories from Woocommerce widget - woocommerce

Question

We want to hide/exclude a few specific woocommerce category from the woocommerce shop as well as all pages.
So far we managed to achieve this using code I found on the internet.
The code bellow hide the correct category from the shop page but when we do a search using the woocommerve search, the category are not hidden in the result page.
//Insert excluded category ids here
$excludes = array(3380,3308);
$includes = explode(",",$widget_args['include']);
$includes = array_filter($includes, function($value) use ($excludes) {
return !in_array($value, $excludes);
});
$widget_args["include"] = implode(",", $includes);
return $widget_args;
}
add_filter( 'woocommerce_product_categories_widget_dropdown_args', 'exclude_woocommerce_widget_product_categories');
add_filter( 'woocommerce_product_categories_widget_args', 'exclude_woocommerce_widget_product_categories');
The code bellow does hide the category from the search page but not from the shop page
add_filter( 'woocommerce_product_categories_widget_dropdown_args', 'organicweb_exclude_widget_category');
add_filter( 'woocommerce_product_categories_widget_args', 'organicweb_exclude_widget_category' );
function organicweb_exclude_widget_category( $args ) {
$args['exclude'] = array('15', '3380', '3308' ); // Enter the id of the category you want to exclude in place of '30'
return $args;
}
Could anyone please help me merge the 2 pieces of code together?
Thank you in advance.

Answer 1

Both of the code snippets you posted only hide categories from the widget, it has no effect on hiding the category otherwise. Not 100% on what your goal is, two things seem likely to me:
If you want to Exclude products from a particular category on the shop page do it with below code (does not hide the category, if you selected to show them under Design > Customizer > WooCommerce > Product Catalogue in the backend) as seen in the WooCommerce docs.
/**
* Exclude products from a particular category on the shop page
*/
function custom_pre_get_posts_query( $q ) {
$tax_query = (array) $q->get( 'tax_query' );
$tax_query[] = array(
'taxonomy' => 'product_cat',
'field' => 'slug',
'terms' => array( 'clothing' ), // Don't display products in the clothing category on the shop page.
'operator' => 'NOT IN'
);
$q->set( 'tax_query', $tax_query );
}
add_action( 'woocommerce_product_query', 'custom_pre_get_posts_query' );
To actually hide the category itself, do the following as documented here Hide a WooCommerce Category from Shop Page, which does not hide the products of this category.
/**
* Show products only of selected category.
*/
function get_subcategory_terms( $terms, $taxonomies, $args ) {
$new_terms = array();
$hide_category = array( 126 ); // Ids of the category you don't want to display on the shop page
// if a product category and on the shop page
if ( in_array( 'product_cat', $taxonomies ) && !is_admin() && is_shop() ) {
foreach ( $terms as $key => $term ) {
if ( ! in_array( $term->term_id, $hide_category ) ) {
$new_terms[] = $term;
}
}
$terms = $new_terms;
}
return $terms;
}
add_filter( 'get_terms', 'get_subcategory_terms', 10, 3 );
