我刚刚设法使用 php 文件在我的网站模板上设置了一个联系表格，并在此处的论坛上提供了一些帮助，但现在我收到了我想要的电子邮件地址的电子邮件，但我收到了 4 个副本，这是一个与没有收到电子邮件相比有轻微的不便，但绝不会更少，我想解决它。
HTML 代码
<div class="grid_12">
<h2 class="">Send Message</h2>
<form id="contact-form2">
<div class="success"> Contact form submitted! <strong>We will be in touch soon.</strong></div>
