Sorting by Stock Status in WooCommerce

WooCommerce, a popular WordPress plugin for e-commerce, offers robust functionality for managing products. One common requirement for store owners is the ability to sort products by their stock status, ensuring that in-stock items are displayed before out-of-stock ones. This can enhance user experience by highlighting available products and potentially increasing sales.

Why Sort by Stock Status?

Sorting products by stock status has several benefits:

1. Improved User Experience: Customers can easily find products that are available for purchase, reducing frustration and enhancing the shopping experience.
2. Increased Sales: Displaying in-stock items first can lead to higher conversion rates as customers are more likely to purchase available items.
3. Better Inventory Management: Highlighting out-of-stock items can remind store owners to restock popular products.

Implementing Stock Status Sorting in WooCommerce

To achieve sorting by stock status in WooCommerce, you can use custom code snippets added to your theme's functions.php file or use a dedicated plugin. Here’s a simple approach using custom code:

1. Add Custom Sorting Option: You can add a custom sorting option to WooCommerce product sorting dropdown.

   php
   Copy code
   add_filter( 'woocommerce_get_catalog_ordering_args', 'custom_sort_by_stock_status' );
   add_filter( 'woocommerce_default_catalog_orderby_options', 'custom_sort_by_stock_status_option' );
   add_filter( 'woocommerce_catalog_orderby', 'custom_sort_by_stock_status_option' );
   
   function custom_sort_by_stock_status( $args ) {
       if ( isset( $_GET['orderby'] ) && 'stock_status' == $_GET['orderby'] ) {
           $args['meta_key'] = '_stock_status';
           $args['orderby'] = array( 'meta_value' => 'ASC', 'date' => 'DESC' );
       }
       return $args;
   }
   
   function custom_sort_by_stock_status_option( $sortby ) {
       $sortby['stock_status'] = 'Sort by stock status';
       return $sortby;
   }
   

2. Modify Product Query: Modify the WooCommerce product query to sort products by stock status.

   php
   Copy code
   add_action( 'pre_get_posts', 'custom_pre_get_posts_query' );
   
   function custom_pre_get_posts_query( $q ) {
       if ( ! is_admin() && $q->is_main_query() && ( is_shop() || is_product_category() || is_product_tag() ) ) {
           if ( isset( $_GET['orderby'] ) && 'stock_status' == $_GET['orderby'] ) {
               $q->set( 'meta_key', '_stock_status' );
               $q->set( 'orderby', array( 'meta_value' => 'ASC', 'date' => 'DESC' ) );
           }
       }
   }
   

Using a Plugin

If you're not comfortable adding custom code, consider using a WooCommerce plugin that offers sorting options. Plugins like "WooCommerce Product Sort and Display" or "Advanced WooCommerce Product Sorting" provide user-friendly interfaces to manage product sorting without coding.

Sorting products by stock status in WooCommerce can significantly enhance the shopping experience by prioritizing available items. Whether through custom coding or using a plugin, this feature is a valuable addition to any WooCommerce store. By implementing this sorting method, store owners can streamline their inventory management and potentially increase sales.

Here are some additional code snippets to enhance sorting by stock status in WooCommerce:

Display Out of Stock Products Last

To ensure out-of-stock products always appear at the end of product listings, you can modify the WooCommerce query:

php
Copy code
add_filter('posts_clauses', 'sort_products_by_stock_status', 10, 2);
function sort_products_by_stock_status($clauses, $query) {
    global $wpdb;

    if (is_admin() || !$query->is_main_query() || !$query->is_post_type_archive('product') && !$query->is_tax(array('product_cat', 'product_tag'))) {
        return $clauses;
    }

    $clauses['join'] .= " LEFT JOIN {$wpdb->postmeta} AS pm ON pm.post_id = {$wpdb->posts}.ID AND pm.meta_key = '_stock_status'";

    $clauses['orderby'] = " pm.meta_value ASC, {$wpdb->posts}.menu_order ASC, {$wpdb->posts}.post_date DESC";

    return $clauses;
}

Sort by Stock Quantity

If you want to sort products by their stock quantity (available stock count), you can use this snippet:

php
Copy code
add_filter('woocommerce_get_catalog_ordering_args', 'custom_sort_by_stock_quantity');
add_filter('woocommerce_default_catalog_orderby_options', 'add_stock_quantity_sort_option');
add_filter('woocommerce_catalog_orderby', 'add_stock_quantity_sort_option');

function custom_sort_by_stock_quantity($args) {
    if (isset($_GET['orderby']) && 'stock_quantity' == $_GET['orderby']) {
        $args['orderby'] = 'meta_value_num';
        $args['meta_key'] = '_stock';
        $args['order'] = 'DESC';
    }
    return $args;
}

function add_stock_quantity_sort_option($sortby) {
    $sortby['stock_quantity'] = 'Sort by stock quantity';
    return $sortby;
}

Display a Custom Message for Out of Stock Products

You can also add a custom message to products that are out of stock:

php
Copy code
add_action('woocommerce_after_shop_loop_item_title', 'display_out_of_stock_message', 10);
function display_out_of_stock_message() {
    global $product;
    if (!$product->is_in_stock()) {
        echo '<p class="out-of-stock">This product is currently out of stock.</p>';
    }
}

Automatically Hide Out of Stock Products

If you prefer to hide out-of-stock products from the catalog, use this code:

php
Copy code
add_filter('pre_get_posts', 'hide_out_of_stock_products');
function hide_out_of_stock_products($query) {
    if (!is_admin() && $query->is_main_query() && (is_shop() || is_product_category() || is_product_tag())) {
        $query->set('meta_query', array(
            array(
                'key' => '_stock_status',
                'value' => 'outofstock',
                'compare' => 'NOT IN'
            )
        ));
    }
}

These snippets can be added to your theme's functions.php file or a custom plugin to enhance the stock status sorting and display functionality of your WooCommerce store.
