【问题描述】：
我是 php 编码的新手。 我的网站上有一个联系表格，允许用户将文件作为附件发送到电子邮件。
根据互联网上的参考资料，我终于通过联系表格发送了电子邮件。所以问题是文件上传到服务器但邮件到达时没有任何附件。
我创建了名为upload 的文件夹，文件只放在那里。 我是不是错过了什么。以下是我正在使用的代码：
HTML：
<form action="send_form_email.php" method="post" enctype="multipart/form-data" name="servicesform" id="servicesform" autocomplete="on">
<div class="control-group form-group">
<div class="controls">
<label class="contact-p1">Full Name:</label>
<input type="text" class="form-control" name="yourname" id="yourname" required data-validation-required-message="Please enter your name.">
<p class="help-block"></p>
</div>
</div>
<div class="control-group form-group">
<div class="controls">
<label class="contact-p1">Phone Number:</label>
<input type="tel" class="form-control" name="phone" id="phone" required data-validation-required-message="Please enter your phone number.">
<p class="help-block"></p>
</div>
</div>
<div class="control-group form-group">
<div class="controls">
<label class="contact-p1">Email Address:</label>
<input type="email" class="form-control" name="email" id="email" required data-validation-required-message="Please enter your email address.">
<p class="help-block"></p>
</div>
</div>
<div class="form-inputs">

不要使用原始的 mail() 函数，使用 PHPMailer 或 SwiftMailer 或其他一些库。不要使用正则表达式来检查电子邮件，使用带有 FILTER_VALIDATE_EMAIL 过滤器的 filter_var() 函数。你的名字正则表达式也不好，例如我的名字包含字符'ý'和'á'，你的过滤器会发现它无效。
-
mail() 函数是唯一的要求。不能使用 PHPMailer 或 Swiftmailer。你能指出这段代码中的问题并纠正它吗？
-
嗯，这不是一个好的要求。请问是什么原因？有空的时候我会尝试修复你的代码。
-
明显的错误是您没有将附件附加到您的电子邮件中。
