我在AMP HTML形式，POST操作;電子郵件的PHP文件使用Sendgrid API。 I was try headers response for Json redirect，但是，沒有工作。AMP PHP聯繫表不重定向（谷歌AMP）
爲此我採用JavaScript重定向（是的，我知道，這產生AMP驗證錯誤，但我需要重定向到感謝頁面跟蹤在線轉化）。
PHP文件工作得很好，所有的郵件都發送給它的，但內部消除JavaScript重定向，只能用DIV成功或錯誤的電子郵件發送，只有我看到錯誤發送電子郵件，但是，自相矛盾，所有的郵件都發送它的無通過Sendgrid API問題LOL）。
因此，我需要使用正確的PHP標頭Json響應（無JavaScript）重定向HTML聯繫表單，以跟蹤在線轉換並正確驗證我的AMP HTML源代碼。在其他情況下，我認爲它是非常有用的製作從PHP文件正確重定向成功提交後（以我嘗試在PHP頭位置重定向，但是，不工作... ...）
形式：
<form method="post"
class="p2"
action-xhr="//example.com/path/themex/amp-theme/path/file.php"
target="_top">
<div class="ampstart-input inline-block relative m0 p0 mb3">

<div submit-success>

<div submit-error>
<template type="amp-mustache">
Error! Thanks {{name}} for trying the

</form>PHP後：
<?php

require_once ('vendor/autoload.php');

/*Send the mail*/
