javascript - WordPress 在特定页面的头部插入谷歌标签管理器代码

Question

尝试将 Google 跟踪代码管理器事件插入我网站一页的头部时遇到问题。

我的functions.php中有这段代码：

function dcl_hook_javascript() {
    if (is_page ('5722')) { 
    ?>
    <!-- Global site tag (gtag.js) - Google Ads: 123456789 -->
    <script async src="https://www.googletagmanager.com/gtag/js?id=AW-123456789"></script>
    <script>
      window.dataLayer = window.dataLayer || [];
      function gtag(){dataLayer.push(arguments);}
      gtag('js', new Date());

      gtag('config', 'AW-123456789');
    </script>
    <!-- Event snippet for Free Trial Request Form Submitted conversion page -->
    <script>
      gtag('event', 'conversion', {'send_to': 'AW-123456789/abcABCDdefEBEOCfx9AC'});
    </script>
        <?php
      }
    }
    add_action('wp_head', 'dcl_hook_javascript');

它只是没有显示在页面上。我怎样才能解决这个问题？
