How to Display Stock Status for Product Variations in WooCommerce Dropdown?

How to Add Variation Stock Status to WooCommerce Product Variation Dropdown

Problem:

WooCommerce does not display the stock status for individual product variations within the dropdown list. This can make it difficult for customers to determine which variations are available.

Solution:

To add variation stock status to the dropdown, you can modify the wc_dropdown_variation_attribute_options function in your WooCommerce installation. This function generates the HTML that is displayed in the dropdown menu.

Code:

<code class="php">add_filter( 'woocommerce_dropdown_variation_attribute_options_html', 'show_stock_status_in_dropdown', 10, 2 );
function show_stock_status_in_dropdown( $html, $args ) {
    // Get the product and attribute.
    $product = $args['product'];
    $attribute = $args['attribute'];

    // Get the variations for the product.
    $variations = $product->get_available_variations();

    // Loop through the variations and get the stock status for each one.
    foreach ( $variations as $variation ) {
        // Get the stock status.
        $stock_status = $variation['is_in_stock'] ? 'In Stock' : 'Out of Stock';

        // Append the stock status to the HTML.
        $html .= '<option value="' . esc_attr( $variation['variation_id'] ) . '" ' . selected( $args['selected'], $variation['variation_id'], false ) . '>' . esc_html( apply_filters( 'woocommerce_variation_option_name', $variation['attributes'][ $attribute ] ) ) . ' - (' . esc_html( $stock_status ) . ')</option>';
    }

    return $html;
}</code>

Explanation:

• The wc_dropdown_variation_attribute_options function is hooked to the woocommerce_dropdown_variation_attribute_options_html filter.
• The function takes two arguments: the HTML that is displayed in the dropdown menu, and an array of arguments that include the product and attribute information.
• The function loops through the variations for the product and gets the stock status for each one.
• The stock status is appended to the HTML, prefixed with the variation attribute name.
• The modified HTML is returned and displayed in the dropdown menu.
