我有一個簡單的PHP聯繫我們的腳本與「謝謝你」通過回顯命令顯示在同一頁面上。一切工作正常，但我的問題是，如果我在回聲部分中包含Google GA跟蹤代碼，那麼在頁面加載期間觸發跟蹤代碼還是僅在實際調用回顯時觸發跟蹤代碼？是否有意義 ？ （我試圖跟蹤轉換 - 有多少人通過網站實際發送電子郵件）回聲和谷歌跟蹤代碼
我正在處理的網站是bplegal.com/demo/contact_us.php。 這裏是PHP代碼：
<style>
.error_message {padding:3px;
font-family:font-family: ‘Arial Narrow’, sans-serif;
font-size:11px;
color:#a0c33f;
text-transform:uppercase;}
</style>
