我正在寻找有关如何使用Restrict Content Pro Wordpress插件扩展发票详细信息的建议。我不确定如何在发票上显示订阅级别的细分。我用他们的代码弄清楚了学习的曲线。我已经附上了invoice.php，该如何解决？
我的难题：我的订阅费用为295美元。细目如下：会员费-195 $，保险单-100 $。我只需要显示细目，它可能非常简单。
我确实尝试仅放置ul标签，并列出带有li标签的细目分类。但是，这会引起混乱，因为它将显示所有具有不同级别的发票。
发票代码：
<body>
<div id="main">
<header id="header">
<!-- Logo -->
<div class="logo">
<?php if ( ! empty( $rcp_options['invoice_logo'] ) ) : ?>
<img src="<?php echo esc_attr( $rcp_options['invoice_logo'] ); ?>" />
<?php endif; ?>
