• PHP mail function doesn't complete sending of e-mail 27 answers

I have a contact form on my website and it does not seem to be sending emails. It was on a server when I have been testing it.

Here is the form.

    <form  action="" method="post" name="form">
        <input type="text" name="name" />
        <input  type="email" name="email" />
        <textarea name="message" ></textarea>
        <input  name="submit" type="submit" value="Submit">
    </form>

And here is the PHP code.

   <?php
        if(isset($_POST["submit"])){
        if($_POST["name"]==""||$_POST["email"]==""||$_POST["message"]==""){
        echo "Please fill in the contact form";
        }else{

        $to = "[e-mail]";
        $subject = "Contact Form";
        $name= $_POST['name'];
        $email= $_POST['email'];
        $message= $_POST['message'];
        $headers = "From: [e-mail]";

        mail($to,$subject,$name,$email,$message,$headers);

        }
        }
     ?>

I have changed my email address to a dummy one there but it does I have not recieved any emails when I do submit this form though.

Thanks in advance! :)

$subject = "My subject";
$txt = "Hello world!";
$headers = "From: [e-mail]" . "
" .
"CC: [e-mail]";

mail($to,$subject,$txt,$headers);

//syntax mail(to,subject,message,headers,parameters);
