php, check if mail is valid

Question

I know that there is a ton of solutions to this problem but i need to validate email in a contact form.

this is my php mailer so far:

<?php
if (isset($_POST['send'])){ 
     $to = "mail@mail.something"; 
     $subject = "new message"; 
     $firstname = $_POST['name'];
     $email = $_POST['email'];
     $message = $_POST['message']; 
     $headers = "From: $email"; 
     $sent = mail($to, $subject, $message, $headers) ; 
     if($sent) 
     {echo "<script>alert('thanks for the message:) ');</script>"; 
    }else
        {echo "<script>alert('sorry, message wasn't send');</script>"; }
    }
?>

I have tried with filter_var

$result = filter_var( 'something@something.something', FILTER_VALIDATE_EMAIL );

but, doesn't work.

If my way to sent mail through contact form isn't the "best practice way" feel free to correct me and send me on the right path :D

put `error_reporting(E_ALL);` and check if there;s any error — ɹɐqʞɐ zoɹǝɟ, Jan 26 '15 at 05:18

I think you may need to describe what is not working about it. — Rasclatt, Jan 26 '15 at 05:22
"but, doesn't work." tells us nothing. Enable error reporting and tell us the error code — ecnepsnai, Jan 26 '15 at 05:22
Well.. i would like to tell you more about it, but all i get is a blank screen when i ask if $result and validate is true, then send mail. I will try error reporting as soon as i get home from work. — Morten Pradsgaard, Jan 26 '15 at 05:24

If you show us your HTML we can help further, but with just your PHP we don't have much to work with.

Add error_reporting(E_ALL); and ini_set('display_errors', 1); to the top of your php page to print your errors.

I am not sure what is causing your errors. But i would like you to try the following code. Replace your if statement with this.

Future note, to add a javascript alert in php you should format it this way,

if(mail($to, $subject, $message, $headers))
{
    echo '<script language="javascript">'; //echo open tag
    echo 'alert("Your message has been sent")'; // echo alert
    echo '</script>'; //echo close tag
}else{
    echo '<script language="javascript">';
    echo 'alert("Your message was not successful")';
    echo '</script>'; 
}
