My form, regarding the email bit - php

Question

I've searched stack but couldn't find something similar. I found a nice php script with a robot attached to the form. It works when I send a message and I do receive it. BUT, the email bit doesn't show up in the mail. Maybe you can find something more that is wrong. It's all in Swedish so nevermind the text :P
<?php
if($_POST){
$to = 'my#mail.com';
$subject = 'Portfolio-mail';
$from_name = $_POST['name'];
$from_email = $_POST['email'];
$message = $_POST['message'];
$robotest = $_POST['robotest'];
if($robotest)
$error = "* Misstänkt för att vara en robot, vad god försök igen!";
else{
if($from_name && $from_email && $message){
$header = "Från: $from_name, $from_email";
if(mail($to, $from_email, $from_name, $message))
$success = "Ditt meddelande har skickats!";
else
$error = "* Du är mänsklig, men det var ett fel med din förfrågan!";
}else
$error = "* Alla fält måste vara ifyllda!";
}
}
?>
And for the input bit:
<form action="" method="POST" autocomplete="off">
<div class="formLeft">
<label>För- & Efternamn:</label>
<input type="text" id="name" name="name" placeholder="John Doe" required="required">
<label>Email-adress:</label>
<input type="text" id="email" name="email" placeholder="Fyll i din email-adress!" required="required">
</div>
<div class="formRight">
<label>Skriv gärna in några ord angående projektet.</label>
<textarea id="textarea" name="message" placeholder="Klicka i denna ruta för att börja skriva..." required="required"></textarea>
<p class="robotic" id="pot">
<label>If you're human leave this blank:</label>
<input name="robotest" type="text" id="robotest" class="robotest" />
</p>
<input type="submit" value="Skicka!" />
</div>
</form>
That's it! If you need more information, don't hesitate to ask!

Answer 1

You are using the php mail function incorrectly:
mail($to,$subject,$message,$headers);
You have
if(mail($to, $from_email, $from_name, $message))
With your code you have many of these variables you just aren't using them, it should be
if(mail($to, $subject, $message, $header))
In the future please at least look at the php documentation before posting a question. http://php.net/manual/en/function.mail.php
