I've created a simple PHP contact form, and when I enter the information, I do receive the "Thank You For Your Email" message, but nothing is sent to my email. I'm using awardspace (the free version) for hosting, could it be a problem with my hosting plan?

Its hard to tell what the problem might be without a look at your code.

As NullPointer said, you should show the source code first, but I'm 99 % sure, your hosting service has forbidden using mail() function, as most of the free services do.

Here is my code

PHP Code:

<?php
if(isset($_POST['submit'])) {
$to = "a_sadrossadat@yahoo.com";
$subject = "Email From Site";
$name_field = $_POST['name'];
$email_field = $_POST['email'];
$message = $_POST['message'];
 
$body = "From: $name_field\n E-Mail: $email_field\n Message:\n $message";

echo "Data has been submitted to $to!";
mail($to, $subject, $body);
} else {
echo "blarg!";
}
?>

Your email does not contain any headers. At a minimum it should contain a from field.

Check out the documentation:
http://us.php.net/function.mail

I'm not quiet sure what you mean

Take a look at the link I posted for more info, but in short the mail function has a fourth parameter additional headers. This is technically an optional parameter but without specifying from in the headers you message will not be sent.

PHP Code:

$headers = "From: email@address.com \r\n";
mail($to, $subject, $body, $headers); 


Headers can also be used to specify document type, include attachments, and add cc and bcc fields.

I think he ment headers like this.

PHP Code:

$to = 'nobody@example.com';
$subject = 'the subject';
$message = 'hello';
$headers = 'From: webmaster@example.com' . "\r\n" .
    'Reply-To: webmaster@example.com' . "\r\n" .
    'X-Mailer: PHP/' . phpversion();

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


It looks like you are missing the message in your mail().

PHP Code:

$to = "a_sadrossadat@yahoo.com"; 
$subject = "Email From Site"; 
$name_field = $_POST['name']; 
$email_field = $_POST['email']; 
$message = $_POST['message']; 
  
$body = "From: $name_field\n E-Mail: $email_field\n Message:\n $message"; 
mail($to, $subject, $message, $body); 
?> 


if you do it like that it might work. Or mail() isn't supported by your host.

Thanks a lot guys, I tried all of your solutions but I'm still not receiving any emails.
I think the problem is my hosting plan, Thanks again.

99.99999999% of free hosting providers don't allow PHP to send email because of spammers. If you really need to send email, you should by shared hosting somewhere. You can get it for around $5 a month (which is really quite cheap when you think about it).

Your hosting is the problem. Try to contact your hosting and ask them that you had an email form on your site. They will give you the .htaccess code so that you can receive the email. I think the code is something like global.
