Support » Plugin: WooCommerce » WC 3.3.1 New issues with product category display

  • Resolved Steve Weigold


    Updated versions of WooCommerce and Storefront. Problem I’m having after update is SOME, not all categories are not displaying as expected. The linked page above is one example. My categories are set to display both subcategories and products, but I have a modification in my child theme because I only want the products displayed for the category being view and not the products of the subcategories. The code for this is below.

    This has worked on all categories up until the 3.3.1 update I believe. Now, it works for many still, but not all. Generally, I find that now in a product category that doesn’t have any products, only subcategories, I get the “no products found” message.

    Things I’ve tried:
    – No caching plugins in use
    – Clearing browser caches, WooCommerce counters etc has no effect
    – On the errant pages, no changes to display settings has any effect
    – If I add a test product to the errant category, the category and subcategories display as expected.
    – If I remove my exclude code below, most pages display with products, subcategories and subcategory products as I would expect, BUT, the errant categories display subcategories, but NOT subcategory products, so are still displaying incorrectly based on settings.

    Help please!

    Exclude code:

    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');

  • Here is my working code. Had to add a count check in the conditional

    function modify_category_products($query)
            if($query->get('product_cat') && !is_admin() && $query->queried_object->count > 0)
                $tax_query = $query->get('tax_query');
                $cat = get_term_by('slug', $query->get('product_cat'), 'product_cat');
                $subcats = get_terms( 'product_cat', array(
                    'parent' => $cat->term_id
                ) );
                $child_cats = array();
                foreach($subcats as $cat)
                    array_push($child_cats, $cat->term_id);
                $new_tax_query = array(
                        'taxonomy' => 'product_cat',
                        'field' => 'id',
                        'terms' => $child_cats,
                        'operator'=> 'NOT IN'
                    $tax_query = array();
                array_push($tax_query, $new_tax_query);
                $query->set('tax_query', $new_tax_query);
    add_filter( 'pre_get_posts', 'modify_category_products' );

    @mikejolley This is necessary because my Utility category is set to Both. But when that happens it displays:
    – the subcategory(ies)
    – the direct child products
    – and the subcategories’ products (which we do not want). it should only be displaying the subcategories and direct child products.

    Plugin Author Mike Jolley (a11n)


    I’m not talking about the global setting. There is a setting per category you can edit. This has been in place for years.

    Bypassing WC and editing core queries will have side effects. In this case, a category with no children won’t be visible. Your query changes the product counts.

    Use the setting – I’m pretty confident it does what you’re after. No code required.

    Thread Starter Steve Weigold


    So, here’s the link to my test site, with the query adjustment in place:

    You can see the desired behavior in “Indoor Lighted” where we show products in that category and subcategories, but not the products in the subcategories.

    “Outdoor Lighted” is the category that ONLY has subcategories and of course, it’s broken now.

    WooCommerce doesn’t have the capability of doing this type of configuration natively. Further, this approach worked properly up until a recent update, so something changed that broke this approach. I need to come up with a solution. If modifying the query isn’t it, I’d appreciate some help on what is.

    Thread Starter Steve Weigold


    @mikejolley, the setting does not. I have changed the test site again and edited the setting for the category itself. Indoor Lighted in my test site now only shows subcategories. The product that is in Indoor Lighted is now no longer visible.

    Here’s the link to the product in the Indoor Lighted category which is no longer visible:

    I think there is a disconnect in desired behavior.

    I AM going into a specific category’s settings to change the display.
    If I change it to Both (for my Utility category for example):
    – that category’s subcategories display as they should
    – that category’s direct child products display as they should
    – any subcategory’s products are also getting displayed (which is undesired for our site)
    – This has been the case before 3.3.1. Regardless if a category is set to display Products or Both it displays all products regardless of it being a direct descendent of the category or in a subcategory.
    – This default behavior of WC is not desired for our website, therefore I wrote the code that I did – to only display direct descendent products of the current category and remove those in subcategories.
    – With the 3.3.1 update, the pre_get_posts was affected but I fixed by adding a count check to the conditional as mentioned.

    @sweigold It sounds like you might be trying to implement the same effect? If so, have you tried adding my working snippet to your site?

    Thread Starter Steve Weigold


    @pinksharpii I am trying to do exactly that. I overlooked your working code until a few minutes ago and so just now added it to mine. Thank you so much! You saved me from having to figure out that myself 🙂

    Thread Starter Steve Weigold


    @mikejolley, @pinksharpii’s explanation in his last post is spot on. Maybe this needs to be a feature request?

    Thread Starter Steve Weigold


    I’m going to mark this issue as resolved. Thanks everyone.

    Plugin Author Mike Jolley (a11n)


    Ok I can see why it happens now and why the count based snippet would fix.

    To work in shortcodes and via templates, 3.3 prepends the products loop with subcategories. By default, there will always be products if there are categories.

    This snippet removes those products so have_posts returns false. There is therefore no loop, and no categories get prepended. The ‘no products exist’ notice is rendered instead.

    Making a note, thanks.

    I am having the same issue, I was using the same exlude code that Sweigold posted. It used to work fine, but after the new woocommerce updates(like 2 weeks ago) it stopped working. Any solutions?

    Thanks in advance

    Sadly we also encounter this problem, especially since the latest woocommerce 3.3.3.
    Where also the script from @pinksharpii is not working and is still resulting in no products found.

    We have several shops were we would like to see this behaviour as described in this topic which we included since longtime with a similar script as in the post starter topic from @sweigold

    I hope anyone has a clue how to solve this since we have several shops that use this functionality to not display products from subcategories in the main category but only these products that are connected to the current group. And i think it would be a great feature request since the inital code can be found on many sites as a solution to this question, it looks like many people use this behaviour.

    I am having the exact same issue on a few sites.

    Has anyone had any luck in re-writting the snippet?

    @wordmonkey25 I have been looking around for some time now, but i couldn’t find a solution 🙁
