I am using on of the Widgets included with WooCommerce called Filter products by attribute. I created a widgetized area on the category page in my Storefront-child-theme functions.php
(see code below).
But when I filter by attribue size M
for example, it lists products where size M is out of stock…
Any idea how to fix this?
EXAMPLE: Filtering by size M displays this product, which is not available:
/* FILTER BY SIZE WIDGET */ // Adding the widget area. if (function_exists('register_sidebar')) { register_sidebar(array( 'name' => 'Below category title', 'id' => 'extra-widget-area', 'description' => 'Below category title', 'before_widget' => '<div class="widget below-cat-title-widget">', 'after_widget' => '</div>', 'before_title' => '<h6 class="below-cat-title-widget-title">', 'after_title' => '</h6>' )); } // placing the widget add_action( 'woocommerce_archive_description', 'add_my_widget_area', 31 ); function add_my_widget_area() { if (function_exists('dynamic_sidebar')) { dynamic_sidebar('Below category title'); } } add_action( 'woocommerce_archive_description', 'filter_button_function', 21 ); function filter_button_function() { // if ( is_product_category() ) { // global $wp_query; // $cat_id = $wp_query->get_queried_object_id(); // $cat_desc = term_description( $cat_id, 'product_cat' ); if (get_locale() == 'fr_FR') { $filter_html = '<div class="filter_by_size" class="subtitle">'.'FILTRE PAR TAILLE'.' <span class="filter-icon"></span>'.'</div>'; } else { $filter_html = '<div class="filter_by_size" class="subtitle">'.'FILTER BY SIZE'.' <span class="filter-icon"></span>'.'</div>'; } echo $filter_html; // } }

Answer
I’ll be direct : by default, you can’t. It’s not related to a certain theme or plugin, but to Woocommerce itself. This is a problem that exists in woocommerce for a very long time. It’s not possible by default in woocommerce to handle variable products stock visibility (stock status) based on it’s variations visibility as it’s something necessary and needed by Woocommerce1.
A way of doing this is to add this action function :
add_action('woocommerce_before_shop_loop_item', 'out_of_stock_variations_loop'); function out_of_stock_variations_loop() { global $product; $filter = 'size'; if ($product->product_type === 'variable') { $available = $product->get_available_variations(); if ($available) { foreach ($available as $instockvar) { if (isset($instockvar[ 'attributes' ][ 'attribute_pa_' . $filter ])) { if ($_GET[ 'filter_' . $filter ]) { if ( !in_array( $instockvar[ 'attributes' ][ 'attribute_pa_' . $filter ], explode(',', $_GET[ 'filter_' . $filter ]) , true ) || ($instockvar[ 'max_qty' ] <= 0) ) { echo "<style>.post-" . $product->get_id() . " {display: none}</style>"; } else { echo "<style>.post-" . $product->get_id() . " {display: list-item !important}</style>"; } } } } } } } ?>
Which will only show the list of products in stock. The problem with this is that it will leave blank spaces where the not-in-stock products are deleted by this query, and it can be difficult to circumvent this problem only with css because, on each row, first and last products have first
and last
classes that determines their layout in CSS. To overcome this, add this jQuery to your child-theme js script:
function openLayeredNavFilterIfSelected() { if (jQuery('.wc-layered-nav-term').hasClass('woocommerce-widget-layered-nav-list__item--chosen')) { /*keep layered nav filter open, if at least an attribute is selected*/ jQuery('.woocommerce-widget-layered-nav-list__item--chosen').parent().parent().show(); if (!jQuery('.filter-icon').hasClass('arrow_up')) { jQuery('.filter-icon').addClass('arrow_up'); } /*redistribute products rows to avoid missing spaces*/ jQuery('.site-main ul.products.columns-3 li.product').removeClass('first').removeClass('last'); jQuery('.site-main ul.products.columns-3 li.product:visible').each(function(i) { if (i % 3 == 0) jQuery(this).addClass('first'); //add class first to firsts products of rows if (i % 3 == 2) jQuery(this).addClass('last'); //add class last to lasts products of rows }); } } openLayeredNavFilterIfSelected(); jQuery(window).resize(openLayeredNavFilterIfSelected);
And you should be good to go.
