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>
    <fieldset>
        <label class="name">
            <input type="text" value="Name">
            <span class="error">*This is not a valid name.</span>
            <span class="empty">*This field is required.</span>
            <span class="clear"></span>
        </label>
        <label class="email">
            <input type="text" value="E-mail">
            <span class="error">*This is not a valid email address.</span>
            <span class="empty">*This field is required.</span>
            <span class="clear"></span>

    </fieldset>
</form>
