我正在尝试添加一个 if 语句，如果 url 等于某个位置，则该语句仅在此 wordpress 插件中执行移动重定向。我假设它将放置在确定浏览器是否移动的位置。我尝试了几段不同的代码，但都没有成功。任何帮助将非常感激。

你有没有尝试过：

if($_SERVER["REQUEST_URI"] == "http://www.example.com/test.html") {
  // Logic here.
}

此脚本中的这一行是确定的

if($mobile_browser>0) { return true; }
        else { return false; }

在其中放入另一个条件

$certainLocation = "www.example.com/homepage";

if($mobile_browser>0 && $_SERVER["REQUEST_URI"] == $certainLocation) { return true; }
            else { return false; }
