php - WordPress PHP功能文件中的Google Analytics(分析)代码404错误跟踪

我想在每个页面上显示Google Analytics（分析），但我想在404模板页面上显示它稍有不同。

我有2个分析代码。每个页面上都会显示其中之一。另一个仅用于显示404页。

这是我正在处理的php代码，已插入到功能文件中。我无法正常工作。到目前为止，它所做的只是执行else语句。请帮忙。

if ( is_404() ) {
// Include the Google Analytics Tracking Code in 404
function google_analytics_tracking_code_404(){ ?>

<script>
  (function(i,s,o,g,r,a,m){i['GoogleAnalyticsObject']=r;i[r]=i[r]||function(){
  (i[r].q=i[r].q||[]).push(arguments)},i[r].l=1*new Date();a=s.createElement(o),
  m=s.getElementsByTagName(o)[0];a.async=1;a.src=g;m.parentNode.insertBefore(a,m)
  })(window,document,'script','//www.google-analytics.com/analytics.js','ga');

  ga('create', 'UA-XXXXXXXX-23', 'mydomainname.com');
  ga('send', 'pageview', '404/?url='+ document.location.pathname + document.location.search +'&ref=' + document.referrer);

</script>

<?php }

// include tracking code before the closing head tag
add_action('wp_head', 'google_analytics_tracking_code_404');

// OR include tracking code before the closing body tag
// add_action('wp_footer', 'google_analytics_tracking_code');
}
else {
// Include the Google Analytics Tracking Code
function google_analytics_tracking_code(){ ?>

<script>
  (function(i,s,o,g,r,a,m){i['GoogleAnalyticsObject']=r;i[r]=i[r]||function(){
  (i[r].q=i[r].q||[]).push(arguments)},i[r].l=1*new Date();a=s.createElement(o),
  m=s.getElementsByTagName(o)[0];a.async=1;a.src=g;m.parentNode.insertBefore(a,m)
  })(window,document,'script','//www.google-analytics.com/analytics.js','ga');

  ga('create', 'UA-XXXXXXXX-23', 'mydomainname.com');
  ga('send', 'pageview');

</script>

<?php }

// include tracking code before the closing head tag
add_action('wp_head', 'google_analytics_tracking_code');

// OR include tracking code before the closing body tag
// add_action('wp_footer', 'google_analytics_tracking_code');
}

最佳答案

函数is_404（）需要在wp_head的hook中调用。

// Include the Google Analytics Tracking Code in 404
function google_analytics_tracking_code_404(){ ?>
    if ( is_404() ) { ?>

        <script>
          (function(i,s,o,g,r,a,m){i['GoogleAnalyticsObject']=r;i[r]=i[r]||function(){
          (i[r].q=i[r].q||[]).push(arguments)},i[r].l=1*new Date();a=s.createElement(o),
          m=s.getElementsByTagName(o)[0];a.async=1;a.src=g;m.parentNode.insertBefore(a,m)
          })(window,document,'script','//www.google-analytics.com/analytics.js','ga');

          ga('create', 'UA-XXXXXXXX-23', 'mydomainname.com');
          ga('send', 'pageview', '404/?url='+ document.location.pathname + document.location.search +'&ref=' + document.referrer);

        </script>
    <?php }
}

// include tracking code before the closing head tag
add_action('wp_head', 'google_analytics_tracking_code_404');
