Form not sending email - php

Question

I am having trouble sending the information from my PHP form to the email address. I am fairly new to PHP. Code is below:
if(isset($_POST['submit'])) {
$name = $_POST['name'];
$email = $_POST['email'];
$subject = $_POST['subject'];
$message = $_POST['message'];
$myEmail = "shivambh28#gmail.com";
if (empty($name) || empty($subject) || empty($message)) {
$error = 'Please make sure to double check the fields for errors.';
} elseif (!filter_var($email1, FILTER_VALIDATE_EMAIL)) {
$error = 'Email is incorrect';
} else {
$headers .= "From: $email\r\n";
$headers .= "Reply-To: $myEmail\r\n";
$headers .= "Return-Path: $myEmail\r\n";
$headers .= "CC: $email\r\n";
$headers .= "BCC: $myEmail\r\n";
if ( mail($to,$subject,$message,$headers) ) {
$to = $myEmail;
$subject = $subject;
$message = $message;
$from = $email;
$headers = "From:" . $from;
echo "Mail Sent.";
} else {
echo 'failure to send email';
}
}
}
HTML:
<form id="contactForm" class="form-horizontal" action="<?php echo get_option('home'); ?>/email/" method="POST">
<input id="name" name="name" placeholder="Full Name" type="text">
<input id="subject" name="subject" placeholder="Subject" type="text">
<input id="email" name="email" placeholder="Email Address" type="email">
<textarea placeholder="Your Message" id="message" name="message" rows="10"></textarea>
<input type="submit" value="SEND" class="btn btn-primary btn-block">
</form>
NOTE: I am using WP CMS.

Answer 1

Your form is missing the method attribute. edit the code so that your form has method POST.
<form id="contactForm" class="form-horizontal" action="contact.tpl.php" method="POST">
secondly remove one of your mail function calls. if not your email will be sent twice

Answer 2

Form method POST is missing in the form tag.
<form id="contactForm" class="form-horizontal" action="contact.tpl.php" method="post">

Answer 3

You have wrong parameter $to in mail()
Try
....
....
//// use $email here not $to which is not initialised yet
if ( mail($email,$subject,$message,$headers) ) {
is place of
if ( mail($to,$subject,$message,$headers) ) {

Answer 4

Change your code.It was sending mail by 2times
$to = $myEmail;
$subject = $subject;
$message = $message;
$from = $email;
$headers = "From:" . $from;
if ( mail($to,$subject,$message,$headers) ) {
echo "Mail Sent.";
} else {
echo 'failure to send email';
}
And your form method is like POST
<form id="contactForm" class="form-horizontal" action="contact.php" method="post">
And main thing your file name is either contact.php or contact.tpl NOT contact.tpl.php

Answer 5

$to = $myEmail;
$subject = $subject;
$message = $message;
$from = $email;
$headers = "From:" . $from;
if(#mail($to, $subject, $message, $headers)) {
echo "Mail Sent";
} else {
echo "Fail";
}

Answer 6

There's a . (period) missing from the first $headers variable declaration. Might help.
