在 Woocommerce 单一产品页面中显示特定产品标签的自定义内容

我使用下面的内容在 WooCommerce 单一产品页面中添加自定义 html 或文本，简短描述后：函数 my_content( $content ) { $内容.=' 在简短描述后，我使用以下内容在 WooCommerce 单个产品页面中添加自定义 html 或文本： function my_content( $content ) { $content .= '<div class="custom_content">Custom content!</div>'; return $content; } add_filter('woocommerce_short_description', 'my_content', 10, 2); 如何在包含特定产品标签的产品页面上限制此功能（不是产品类别）？您可以使用 has_term() WordPress 条件函数，限制您的自定义内容仅针对具有特定产品标签的产品显示，如下所示（在函数中定义您的产品标签术语）））： add_filter('woocommerce_short_description', 'my_content', 10, 2); function my_content( $content ) { // Here define your specific product tag terms (can be Ids, slugs or names) $product_tags = array( 'Garden', 'Kitchen' ); if( has_term( $product_tags, 'product_tag', get_the_ID() ) ) { $content .= '<div class="custom_content">' . __("Custom text!", "") .
