我已经托管了网站，创建了表单和PHP，但我无法获得实际发送电子邮件的表单。我确信我把所有的变量都列对了。表单确实提交了，在用户提交内容后，警报会弹出，表单不会显示，但我从未收到电子邮件。这是我的代码：
<?php
if (isset($_REQUEST['email']) && isset($_REQUEST['fullname'])) {
//Email information
$admin_email = 'myemail.hotmail.co.uk';
$fullname = $_REQUEST['fullname'];
$email = $_REQUEST['email'];
$phone = $_REQUEST['phone'];
$followup = $_REQUEST['followup'];
$comment = $_REQUEST['comment'];
//send email
mail($admin_email, $fullname, $comment, 'From: ' . $email . 'Phone: ' . $phone . 'Follow up? ' . $followup);
//Email response
$contactThanks = "Thank you for contacting us!";
echo "<script type='text/javascript'>alert('$contactThanks');</script>";
}
//if 'email' variable is not filled out, display the form
else {
?>
<form action='<?php echo $_SERVER['PHP_SELF']; ?>' method='post'>
<table class='contactForm'>
<tr>
<td><label for='fullname'>*Full Name:</label></td>
<td><input type='text' name='fullname' id='fullname' /></td>
</tr>
<tr>
<td><label for='email'>*Email:</label></td>
<td><input type='text' name='email' id='email' /></td>
</tr>
<tr>
<td><label for='phone'>Phone:</label></td>
<td><input type='tel' name='phone' id='phone' /></td>
</tr>
<tr>
<td><label for='followup'>Follow Up:</label></td>
<td><input type='text' name='followup' id='followup' /></td>
</tr>
<tr>
<td><label for='comments'>Comments:</label></td>
<td><textarea type='text' name='comments' id='comments'></textarea></td>
</tr>
<tr>
<td id='inputButtons' colspan='2'>
<input type='submit' value='Submit' id='submit'/>
<input type='reset' value='Reset' id='reset'/>
</td>
</tr>
</table>
</form>
<?php
}
?>
有人明白为什么不起作用吗？谢谢
将mail函数的返回值分配给一个变量，并检查邮件是否实际发送。例如：
$sent = mail($admin_email, $fullname, $comment, 'From: ' . $email . 'Phone: ' . $phone . 'Follow up? ' . $followup);
if ($sent) {
// thanks, mail sent
} else {
// error, mail failed to send
}
我怀疑您的服务器上没有安装邮件服务器（例如sendmail）。
