Php “显示”；“缺货”；商业中的产品变化

我想对我的网站做一些修改，但由于某种原因，我可以得到它。我尝试使用此函数，发现：

函数看起来像返回

return $term_name .= ' - ' . $stock_status;

一直如此。有什么帮助吗？从我的问题预览可以看到。谢谢

编辑：这是单选按钮插件中的代码，其中将变体打印为单选按钮：

<td class="value">
                        <?php
                        if ( ! empty( $options ) ) {
                            if ( taxonomy_exists( $name ) ) {
                                // Get terms if this is a taxonomy - ordered. We need the names too.
                                $terms = wc_get_product_terms( $product->get_id(), $name, array( 'fields' => 'all' ) );

                                foreach ( $terms as $term ) {
                                    if ( ! in_array( $term->slug, $options ) ) {
                                        continue;
                                    }
                                    print_attribute_radio( $checked_value, $term->slug, $term->name, $sanitized_name );
                                }
                            } else {
                                foreach ( $options as $option ) {
                                    print_attribute_radio( $checked_value, $option, $option, $sanitized_name );
                                }
                            }
                        }

                        echo end( $attribute_keys ) === $name ? 
apply_filters( 'woocommerce_reset_variations_link', '<a 
class="reset_variations" href="#">' . __( 'Clear', 'woocommerce' ) . '</a>' 
) : '';
                        ?>
                    </td>

可能需要更新那里的内容才能正确显示？

请改为这样做

if( $stock_qty>0 )
    //return $term_name .= ' - ' . $stock_status . ' ('.$stock_qty.')';
    return $term_name;
else
    //return $term_name .= ' - ' . $stock_status;
return $term_name .= ' - Out Of Stock';

<td class="value">
                        <?php
                        if ( ! empty( $options ) ) {
                            if ( taxonomy_exists( $name ) ) {
                                // Get terms if this is a taxonomy - ordered. We need the names too.
                                $terms = wc_get_product_terms( $product->get_id(), $name, array( 'fields' => 'all' ) );

                                foreach ( $terms as $term ) {
                                    if ( ! in_array( $term->slug, $options ) ) {
                                        continue;
                                    }
                                    print_attribute_radio( $checked_value, $term->slug, $term->name, $sanitized_name );
                                }
                            } else {
                                foreach ( $options as $option ) {
                                    print_attribute_radio( $checked_value, $option, $option, $sanitized_name );
                                }
                            }
                        }

                        echo end( $attribute_keys ) === $name ? 
apply_filters( 'woocommerce_reset_variations_link', '<a 
class="reset_variations" href="#">' . __( 'Clear', 'woocommerce' ) . '</a>'

                        ?>
                    </td>

if( $stock_qty>0 )
    //return $term_name .= ' - ' . $stock_status . ' ('.$stock_qty.')';
    return $term_name;
