更好的方法是让用户只需输入他们的跟踪脚本IDUA-XXXXXXX-XX?

然后在你的header.php, 输出标准跟踪脚本：

<?php if ( $ga = get_option( \'google_analytics\' ) ) : ?>
    <script>
        var _gaq = _gaq || [];
        _gaq.push([\'_setAccount\', \'<?php echo esc_js( $ga ) ?>\']);
        _gaq.push([\'_trackPageview\']);
        (function() {
            var ga = document.createElement(\'script\'); ga.type = \'text/javascript\'; ga.async = true;
            ga.src = (\'https:\' == document.location.protocol ? \'https://ssl\' : \'http://www\') + \'.google-analytics.com/ga.js\';
            var s = document.getElementsByTagName(\'script\')[0]; s.parentNode.insertBefore(ga, s);
        })();
    </script>
<?php endif ?>
