我是php的新手，希望对您有所帮助，请将recaptcha v2添加到我现有的联系表单中（该表单本身可以正常工作）。
在此处搜索答案只会使我更加困惑如何操作。
recaptcha窗口小部件显示在正确的位置，但是我不知道该行的放置位置。
if ($result['success'] == 1)
我的联系页面代码如下
<?php
$page_title="someone Contact";
$pgKeywords="someone,Contact";
$pgDesc="someone Contact page";
include($_SERVER['DOCUMENT_ROOT']."/header.php");
?>
<script src='https://www.google.com/recaptcha/api.js'></script>

</div>
<p id="pre"><strong>Normally, you should receive a reply from me within 48hrs.
