PHP sending mail problem. pls help

Hello i have a mail form page. I am getting the value from my form but my mail function is not sending the mail. can any one help me?

the code is below:

<?php

$to=$_POST['hemail'];
$from=$_POST['from'];
$sub=$_POST['hatitle'];
$message=$_POST['message'];

mail($to,$sub,$message,$from);
echo"<script>alert (\"You Mail has been send\");history.go(-1)</script>";
else
echo "<span class='red'>Failed to send the E-mail from $mail_sub to $mail_to</span>";

?>

Code (markup):

 

is it give you an error message or what? Maybe your server mail setting?

anyway.. your codes is erroneous.. there's an 'else' without 'if' block

 

sorry the code is :

<?php

$to=$_POST['hemail'];
$from=$_POST['from'];
$sub=$_POST['hatitle'];
$message=$_POST['message'];

if (mail($to,$sub,$message,$from))
echo"<script>alert (\"You Mail has been send\");history.go(-1)</script>";
else
echo "<span class='red'>Failed to send the E-mail from $mail_sub to $mail_to</span>";

?>

im getting the msg "failed to send E mail." Its not sending the mail.

where did you test your script? in your localhost on in your webhost? do you have mailserver installed?

free webhost or paid? usually, free webhost disabled your php mail function. can you post your phpinfo() here?
