PHP联系人表单提交但未接收

我在我的网站上有一张联系表，但是每当我点击提交时，我的电子邮件地址都没有收到任何信息，尽管它说已经提交了

HTML如下所示

<div id="contactform">
    <form name="contact" method="post" action="PHP/send_form_email.php">
    <ol>
        <li><label>To </label>
            <select name="emailaddress" id="emailaddress">
        <option value="0"></option>
        <option value="1">General Queries</option>
        <option value="2">Webmaster Queries</option>
        </select>
        </li>
    <li><label for="name">Name</label>
        <input type="text" name="name" id="name"></input>
        </li>
    <li><label for="email">Email</label>
        <input type="text" name="email" id="email"></input>
        </li>
    <li><label for="subject">Subject</label>
        <input type="text" name="subject" id="subject"></input>
        </li>
    <li><label for="message">Message</label>
        <textarea name="message" id="message" cols="45" rows="5"></textarea>
        </li>
    <li>
            <input name="submit" type="submit" class="submit" id="submit" value="submit"></input>
        </li>
    </ol>
    </form>
</div>

显然，我使用的电子邮件地址不是email1和email2，但我已经检查了我使用的实际地址，它们都键入正确，有人能帮忙吗？

您的

邮件（）中的
$email\u to
和
$email\u subject
未定义

@mail($email_to, $email_subject, $email_message, $headers);

您的
$email\u to
可能应该是
$emailaddress
，基于

else $emailaddress = $emailaddress[$contactnameindex];

$subject = $_POST['subject'];

您的
$email\u subject
可能应该是
干净的字符串（$subject）
，基于

else $emailaddress = $emailaddress[$contactnameindex];

$subject = $_POST['subject'];

比如说——

@mail($emailaddress, clean_string($subject), $email_message, $headers);

您是否尝试过检查
print\r（$\u POST）值？使用
if（mail（））
检查它是否发送邮件或不使用@mail抑制邮件错误是件坏事。我相信Bojan意味着邮件函数调用前面的@in正在抑制错误，您应该删除它以帮助诊断问题。我已尝试更改@mail（$email\u to，$email\u subject，$email\u message，$headers）；到@mail（$emailaddress，clean_string（$subject），$email_message，$headers）；但这并没有起到任何作用，我随后删除了前面的@符号，但它似乎没有改变任何东西。不幸的是，我对PHP非常陌生，虽然我以前做过CSS和HTML，但这对我来说是全新的东西，所以我有点不知道在编码中还能看到什么；到@mail（$emailaddress，clean_string（$subject），$email_message，$headers）；但这并没有起到任何作用，我随后删除了前面的@符号，正如另一条评论所建议的那样，但它似乎没有改变任何东西。不幸的是，我对PHP非常陌生，虽然我以前做过CSS和HTML，但这对我来说是全新的东西，所以我有点不知道在编码中还有什么地方可以看。
