Php 如何在电子邮件成功发送后插入数据

我收到了问题需要帮助..几乎整整一天我都这么做了，但不知道怎么做..我得到了一个带有发送电子邮件和自动回复功能的联系表单..但我需要添加更多功能，比如在成功发送电子邮件后能够插入数据库..我附加了脚本

contact.html

<form action="<?=$_SERVER['PHP_SELF']?>" method="post" id="contact_form" class="hubungi">
          <input name="idContact" type="hidden" value="" />
          <div id="mail_success" class="success"><img src="success.png" />Thanks..</div>
          <div id="mail_fail" class="error"><img src="error.png" /> Sorry, we don't know what happened. Please try again later.</div>
