"\n\n"; $headers = "From:". $from; $headers2 = "From:". $to; mail($to,$subject,$message,$headers); // mail($last_name,$subject2,$message2,$headers2); // sends a copy of the message to the sender echo '<div style="color:#5cad2f; "><b>Thank you '. $first_name. ', we will contact you shortly.</b></div>'; // You can also use header('Location: thank_you.php'); to redirect to another page. }?>

when I enter details and click submit button, nothing is happening, can anyone please help me with this?

Answer 1

Try to know your value is set or not like:

<?php 
     if(isset($_POST['submit']))
     {
          echo "hello world";
     }
?>

when you click submit button if it display hello world that means submit work after that replace name as you show in your input field with $_POST['your_name']

Answer 2

You should use same input name while getting POST values

$from = $_POST['your-email'];
 $first_name = $_POST['your-name'];
 $last_name = $_POST['your-message'];
