联系表单未在 HTML 中显示确认消息

Question

我下载了一个很棒的网站模板，除了联系表格外，一切正常。没有更多对模板的支持，所以现在我来了。

该表单确实向我发送了包含所有数据的电子邮件，但这些消息无法正常工作。

1. 当数据填写错误时，您会收到错误填写的消息。但是当表格填写正确时，该消息不会被删除。
2. 发送电子邮件时，没有显示已发送的消息。
3. 发送电子邮件时，表单不会重置。

我找不到解决办法...

页面上的 HTML。

        <form id="contact-form" class="contact-form" action="#">
            <p class="contact-name">
                <input id="contact_name" type="text" placeholder="Volledige naam" value="" name="name" />
            </p>
            <p class="contact-email">
                <input id="contact_email" type="text" placeholder="E-mail adres" value="" name="email" />
            </p>
            <p class="contact-list">
            <select id="contact_list" size="1" name="reason">
                    <option value="1" selected="selected">Kies de reden voor contact</option>

Answer 1

试试：

        <select id="contact_list" size="1" name="reason">
                <option value="1" selected="selected">Kies de reden voor contact</option>
                <option value="2">Informatie aanvraag</option>
                <option value="3">Offerte aanvraag</option>
                <option value="4">Andere reden</option>
            </select>

Answer 2

解决了消息问题。

我删除了表单中的原因选择字段和 PHP 中的原因类。 不知道为什么它不适用于原因类。

也许有人可以回答这个问题？
