我知道我以前发过这个，但是我在累了凌晨 2 点的时候发了另一个。这个我能很快回复，我想把这个整理一下，我一发布就删除另一个。
好的，所以标题可能有点令人困惑，但请阅读此内容，然后看看它是否更有意义。
我下载了一个 HTML5 网站模板，它带有一个用于表单操作的联系 php 表单。
这是表单的 HTML：
<form id="contact-form" action="bat/MailHandler.php">
<div class="success">
Contact form submitted! <strong>We have received your email and will be with you within 24 hours.</strong>
</div>
<fieldset>
<div>
<label class="topic">
<select style="width:370px;" name="topic">
<option value="General">General</option>
<option value="Development">Development</option>
<option value="Graphics">Graphics Design</option>
<option value="Video">Video Editing</option>
</select>
</label>
</div>
<div>
<label class="name">
<input type="text" value="Your name">
<br>
<span class="error">*This is not a valid name.</span><span class="empty">*This field is required.</span></label>
</div>
<div>
<label class="phone">
<input type="tel" value="Telephone (Please include country code)">
<br>
<span class="error">*This is not a valid phone number.</span><span class="empty">*This field is required.</span></label>
</div>
<div>
<label class="email">
<input type="email" value="Email">
<br>
<span class="error">*This is not a valid email address.</span><span class="empty">*This field is required.</span></label>
</div>
<div>
<label class="message">
<textarea>Message</textarea>
<br>
<span class="error">*The message is too short.</span><span class="empty">*This field is required.</span></label>
</div>
<div class="buttons-wrapper">
<a class="btn btn-1" data-type="reset">Clear</a><a class="btn btn-1" data-type="submit">Send</a>
</div>
</fieldset>
</form>
MailHandler.php 看起来像这样：
<?php
// Database connect
$db_host = 'localhost';
$db_user = 'redjaxco';
$db_pass = 'CORRECT PASSWORD';
$db_database = 'redjaxco_website';
$link = mysql_connect($db_host,$db_user,$db_pass) or die('Unable to establish a DB connection');
mysql_select_db($db_database,$link);
mysql_query("SET names UTF8");
$owner_email = "contact@red-jax.com";
$headers = 'From:' . $_POST["email"];
$subject = 'Online Form: '. $_POST["name"];
$messageBody = "";
if($_POST['name']!='nope'){
$messageBody .= '<p>Visitor: ' . $_POST["name"] . '</p>' . "\n";
$messageBody .= '<br>' . "\n";
}
if($_POST['email']!='nope'){
$messageBody .= '<p>Email Address: ' . $_POST['email'] . '</p>' . "\n";
$messageBody .= '<br>' . "\n";
}else{
$headers = '';
}
if($_POST['phone']!='nope'){
$messageBody .= '<p>Phone Number: ' . $_POST['phone'] . '</p>' . "\n";
$messageBody .= '<br>' . "\n";
}
if($_POST['message']!='nope'){
$messageBody .= '<p>Message: ' . $_POST['message'] . '</p>' . "\n";
}
if($_POST["stripHTML"] == 'true'){
$messageBody = strip_tags($messageBody);
}
try{
if(!mail($owner_email, $subject, $messageBody, $headers))
{
throw new Exception('mail failed');
}
else
{
// ignore the SQL thing... It doesn't yet work
$sql = mysql_query("INSERT INTO customers (
name,email,telephone
) VALUES (
'{$_POST['name']}',
'{$_POST['email']}',
'{$_POST['telephone']}',
)");
if (!$sql)
{
throw new Exception('mail failed');
}
echo 'mail sent';
}
}catch(Exception $e){
echo $e->getMessage() ."\n";
}
?>
MailHandler 由名为“forms.js”的 javascript 文件驱动。
Forms.js：

我的问题是我想在表单顶部添加选择，这将更改邮件的主题，以便可以将它们分类到我的电子邮件帐户上的特定邮箱中。
我尝试添加到 forms.js 但没有效果，也许我做错了。除了 HTML 表单和 MailHandler 之外，所有代码都与我下载模板时的一样。虽然 MailHandler 在我添加选择之前就工作了，但从那以后我就没有改变它。
我不太擅长 JavaScript。HTML 和 PHP 我很好，但 JavaScript 我是新手。我不知道这是 JavaScript 问题还是什么，我猜这是所有功能所在。
