初学者PHP邮件功能问题+服务器错误

Question

So I'm a super beginner to PHP, but I'm currently building my first website and I wanted to have a contact form on the site that a user can fill out, and then have their information be sent to an email.

So I wrote the PHP for this using the "mail()" function, but for some reason whenever the user hits submit, it just goes to a page with the code on it and not the page I linked it to in the echo statement.

Here's my PHP:

<?php 
$name = $_POST['name'];
$email = $_POST['email'];
$phone = $_POST['phone'];
$message = $_POST['message'];
$formcontent="From: $name \n Phone: $phone \n Message: $message";
$recipient = "rowan.krishnan@tufts.edu";
$subject = "Contact Form";
$mailheader = "From: $email \r\n";
mail($recipient, $subject, $formcontent, $mailheader) or die("Error!");
$url = 'contact.html';
echo '<META HTTP-EQUIV=Refresh CONTENT="0; URL='.$url.'">'  
?>

And here's my html:

<div id="emailform">
   <form action="mail.php" method="POST">
       Name: <input type="text" name="name">
       Email: <input type="text" name="email">
       Phone: <input type="text" name="phone">
       Message: <textarea name="message" rows="6" cols="25"></textarea><br />
       <input type="submit" value="Send"><input type="reset" value="Clear">
   </form>
</div>

My final problem is related to the web server/host that I use (hostgator). For some reason, whenever I upload any documents that contain PHP in them, I get a 500 Internal Server Error and I'm not really sure what's going on there. If any of you know what I'm talking about, it would be great if you had advice.

Thanks so much for reading all this and helping out.

Answer 1

You are missing a ; at the end of your echo which is most likely causing the white page

 echo '<META HTTP-EQUIV=Refresh CONTENT="0; URL='.$url.'">';
                                                           ^

try checking your errorlogs to see what errors you have been getting and try turning on error messages

also the message needs to have \\r\\n for each line

$formcontent="From: $name \r\n Phone: $phone \r\n Message: $message";

You cannot run php locally, you need to first be running a web server that has php installed. Try xamp as it is really easy to install and get going and allows you to run your php locally. http://www.apachefriends.org/en/xampp.html

After generating your variables, a simple php email script will look like this.. (which you seem to have correct)

//Generate the email
$headers .= "MIME-Version: 1.0\r\n";
$headers .= "Content-Type: text/html; charset=ISO-8859-1\r\n";
$headers .= 'From: '. $senders_email;

mail($to, $subject, $message, $headers);

As Kai Qing mentioned, use header('location: contact.html'); to redirect the page. echo simply prints to screen whatever you send it. A better approach is to use a callback function in your html document. So you would send the form using a javascript funciton for example, once the response is recieved (your email sent) a callback function would then do what you like, such as show a different page or print a confirmation message.

A jQuery approach would look something like this

//send form to order.php for further processing
var formData = $('#promo-form').serialize();
$.post('order.php',formData,formSent);
//formSent is the callback funciton

Your server 500 errors may be due to the permissions set on your php files. In your ftp client, check the permissions of the php files are set to 0644. Further information about this error can be found at:
