Also I incude the code here.

<?php
if(isset($_POST['submit'])){
$name = $_POST['fullname'];
$branch = $_POST['branch'];
$usn = $_POST['usn'];
$sem = $_POST['sem'];
$email = $_POST['email'];
$subject = $_POST['subject'];
$description = $_POST['comment'];
$to = 'email#example.com';
$display = 'From:</br>Name: $name</br>USN: $usn</br>Branch: $branch</br>Semester: $sem</br>Email: $email</br></br>$description';
mail($to,$subject,$display);
echo "<script>alert('Your Complaint has been succesfully submitted, We will contact you soon.')</script>";

And the rest of code i am not including...

Answer 1

Try this:
$to_address = "Your email address";
$subject = $_POST['subject'];
$headers = "MIME-Version: 1.0\r\n";
$headers.= "Content-type: text/html; charset=iso-8859-1\r\n";
$headers.= "From: ".$email."\r\n";
if (mail($to_address,$subject,$description,$headers)){
echo "Success";
}
else{
echo "<h2>Unable to submit the form, please recheck the details.</h2>" ;
}
Update: If this does not work then there might be an error with your email configuration. As suggested by other users in the comments above, you might want to look into that part too. This answer is based on assumption that your email server/PHP is configured correctly.
