好的，首先，您需要获得以下产品变体：
$variations = $product->get_available_variations();
在期权循环中，您需要遍历所有变化并找到当前的期权库存状态
foreach ($variations as $variation) { if($variation['attributes'][$name] == $option) { $stock = $variation['is_in_stock']; }}在版本循环之外，您需要添加库存和库存不足版本的文字
if( $stock == 1) { $stock_content = ' - In stock';} else { $stock_content = ' - Out of stock';}然后更改html以包含其他变量（$ stock_content）
$html .= '<option value="' . esc_attr( $option ) . '" ' . $selected . '>' . esc_html( $option . $stock_content ) . '</option>';
因此，完整的功能应如下所示：
add_filter( 'woocommerce_dropdown_variation_attribute_options_html', 'show_stock_status_in_dropdown', 10, 2);function show_stock_status_in_dropdown( $html, $args ) { $options = $args['options']; $product = $args['product']; $attribute = $args['attribute']; $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' ); // Get all product variations $variations = $product->get_available_variations(); if ( empty( $options ) && ! empty( $product ) && ! empty( $attribute ) ) { $attributes = $product->get_variation_attributes(); $options = $attributes[ $attribute ]; } $html = '<select id="' . esc_attr( $id ) . '" 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( $attribute ) ) {// Get terms if this is a taxonomy - ordered. We need the names too.$terms = wc_get_product_terms( $product->get_id(), $attribute, array( 'fields' => 'all' ) ); foreach ( $terms as $term ) { if ( in_array( $term->slug, $options ) ) { $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 ) ) . '</option>'; } } } else { foreach ( $options as $option ) { foreach ($variations as $variation) { if($variation['attributes'][$name] == $option) { $stock = $variation['is_in_stock']; } } if( $stock == 1) { $stock_content = ' - (In Stock)'; } else { $stock_content = ' - (Out of Stock)'; } // This handles < 2.4.0 bw compatibility where text attributes were not sanitized. $selected = sanitize_title( $args['selected'] ) === $args['selected'] ? selected( $args['selected'], sanitize_title( $option ), false ) : selected( $args['selected'], $option, false ); $html .= '<option value="' . esc_attr( $option ) . '" ' . $selected . '>' . esc_html( $option . $stock_content ) . '</option>'; } } } $html .= '</select>'; return $html;}
