一点背景信息：

我正在使用重力表单插件，并尝试使用动态自定义确认。然而，所填写的表单有相当多的数据/值变量。然而，我不能使用这些变量。它们根本无法加载。有什么线索吗？请参见下面的代码。

add_filter("gform_confirmation_3", "custom_confirmation", 3, 4 );
function custom_confirmation($confirmation, $form, $lead, $ajax){

if($form["id"] == "3"){


    $confirmation = "
    <br/>
    <center>
    <div class=\'confirmationbuild\'>
    <h2>Your units will arrive in 6 hours</h2> 

    You will be redirected in 3 seconds. <br/><br/>

    <a class=\'confirmationbutton\' href=\'http://www.**********.nl/infantry\'>
    <strong>Click here to be redirected now</strong></a><br/><br/>

    <script type=\'text/javascript\'>
    setTimeout(function () {
    window.location.href=\'http://www.*********.nl/infantry\'; // the redirect goes here
    },2000);  
    </script>

    </div>
    </center>";

}
else if($form["id"] == "5"){
    $confirmation = "Thanks for contacting us. We will get in touch with you soon";
}

return $confirmation;

}
