解决方案:
要在下拉列表中显示每个变体的库存状态,请按照以下步骤操作:
add_filter( 'woocommerce_dropdown_variation_attribute_options_html', 'show_stock_status_in_dropdown', 10, 2); function show_stock_status_in_dropdown( $html, $args ) { // Limiting to single attribute for variations (one dropdown) if( sizeof($args['product']->get_variation_attributes()) != 1 ) { return $html; } $options = $args['options']; $product = $args['product']; $attribute = $args['attribute']; // The product attribute taxonomy $name = $args['name'] ? $args['name'] : 'attribute_' . sanitize_title( $attribute ); $id = $args['id'] ? $args['id'] : sanitize_title( $attribute ); $class = $args['class']; $show_option_none = $args['show_option_none'] ? true : false; $show_option_none_text = $args['show_option_none'] ? $args['show_option_none'] : __( 'Choose an option', 'woocommerce' ); if ( empty( $options ) && ! empty( $product ) && ! empty( $attribute ) ) { $attributes = $product->get_variation_attributes(); $options = $attributes[ $attribute ]; } $html = '<select id="' . esc_attr( $id ) . '" class="' . esc_attr( $class ) . '" name="' . esc_attr( $name ) . '" data-attribute_name="attribute_' . esc_attr( sanitize_title( $attribute ) ) . '" data-show_option_none="' . ( $show_option_none ? 'yes' : 'no' ) . '">'; $html .= '<option value="">' . esc_html( $show_option_none_text ) . '</option>'; if ( ! empty( $options ) ) { if ( $product && taxonomy_exists( $attribute ) ) { $terms = wc_get_product_terms( $product->get_id(), $attribute, array( 'fields' => 'all' ) ); foreach ( $terms as $term ) { if ( in_array( $term->slug, $options ) ) { // Function to get stock status text $stock_status = get_stock_status_text( $product, $name, $term->slug ); $html .= '<option value="' . esc_attr( $term->slug ) . '" ' . selected( sanitize_title( $args['selected'] ), $term->slug, false ) . '>' . esc_html( apply_filters( 'woocommerce_variation_option_name', $term->name ) . $stock_status ) . '</option>'; } } } else { foreach ( $options as $option ) { $selected = sanitize_title( $args['selected'] ) === $args['selected'] ? selected( $args['selected'], sanitize_title( $option ), false ) : selected( $args['selected'], $option, false ); // Function to get stock status text $stock_status = get_stock_status_text( $product, $name, $option ); $html .= '<option value="' . esc_attr( $option ) . '" ' . $selected . '>' . esc_html( apply_filters( 'woocommerce_variation_option_name', $option ) . $stock_status ) . '</option>'; } } } $html .= '</select>'; return $html; } function get_stock_status_text( $product, $name, $term_slug ){ foreach ( $product->get_available_variations() as $variation ){ if($variation['attributes'][$name] == $term_slug ) { $stock = $variation['is_in_stock']; break; } } return $stock == 1 ? ' - (In Stock)' : ' - (Out of Stock)'; }
