我有一个联系表单，在提交时会显示一条感谢信息，将用户输入并通过电子邮件发送到一个地址，但也应该将四个字段放入CSV中。不幸的是，无论我尝试什么，我都无法完成最后一部分工作。
感谢消息有效，发送了一封电子邮件，但我在$output（在if / else之前）添加的部分没有。
这是我正在使用的代码，提前感谢任何可以提供帮助的人。
<?php
$subject = 'Submission received';
$mailto = '';
$firstName = $_POST['firstName'];
$lastName = $_POST['lastName'];
$email = $_POST['email'];
$telephone = $_POST['telephone'];
$company = $_POST['companyName'];
$country = $_POST['country'];
$about = $_POST['hearAbout'];
$enquiry = $_POST['enquiry'];
$body = "
<br>
<p>The following information was submitted through the contact form on your website:</p>
<p><b>Name</b>: $firstName $lastName<br>
<b>Email</b>: $email<br>
<b>Phone number</b>: $telephone</br>
<b>Company name</b>: $company<br>
<b>Country</b>: $country<br>
<b>Heard about company via</b>: $about<br>
<b>Enquiry</b>: $enquiry<br></p>
";
// Success Message - PAD THIS OUT
$success = "
<div class=\"\">
<div class=\"\">
<h3>Submission successful</h3>
<p>Thank you.</p>
</div>
</div>
";
$headers = "From: $firstName $lastName <$email> \r\n";
$headers .= "Reply-To: $email \r\n";
$headers .= "MIME-Version: 1.0\r\n";
$headers .= "Content-Type: text/html; charset=ISO-8859-1\r\n";
$message = "<html><body>$body</body></html>";
$output = $firstName . "t";
$output .= $lastName . "t";
$output .= $email . "t";
$output .= $telephone . "n";
$fp = fopen("data/enquiry.csv", "a");
fwrite($fp, $output);
fclose($fp);
if (mail($mailto, $subject, $message, $headers)) {
echo "$success"; // success
} else {
echo 'Form submission failed. Please try again...'; // failure
}
?>
也许这会有所帮助：
$fp = fopen("data/enquiry.csv", "a");
fwrite($fp,"," . $firstName . "," . $lastName . "," . $email . "," . $telephone . "\n");
fclose($fp);
