I am trying to make a simple form that only has a message box and a submit button.

I took a contact form I am using on another page and just removed all fields I didn't need. The form "appears" to submit but I never receive it in my email. I am sure I have made a simple mistake in the code.

Heres what I am using:

index.php (header):

Code:
<?php 
error_reporting(E_ALL ^ E_NOTICE); // hide all basic notices from PHP

//If the form is submitted
if(isset($_POST['submit'])) {
	
// we need at least some content
	if(trim($_POST['comments']) === '') {
		$commentError = 'You forgot to enter a message!';
		$hasError = true;
	} else {
		if(function_exists('stripslashes')) {
			$comments = stripslashes(trim($_POST['comments']));
		} else {
			$comments = trim($_POST['comments']);
		}
	}
		
	// upon no failure errors let's email now!
	if(!isset($hasError)) {
		
		$emailTo = 'me@gmail.com';
		$subject = 'Submitted message on Site.ca from '.$name;
		$sendCopy = trim($_POST['sendCopy']);
		$body = "Comments: $comments";
		$headers = 'From: ' .' <'.$emailTo.'>' . "\r\n" . 'Reply-To: ' . $email;

		mail($emailTo, $subject, $body, $headers);
        
        // set our boolean completion value to TRUE
		$emailSent = true;
	}
}
?>
index.php (body):

Code:
<div id="actform">
<h3><img src="./_layout/images/bg-checklist.png" />Got an idea?   Let us know below</h3>
<form action="index.php" method="post">
<textarea name="comments" class="actform" placeholder="Message:"></textarea>
<input type="submit" value="Submit" name="submit" class="subname" />
</form>
<div class="spacer"></div>
</div>
Can anyone spot what I am doing wrong? I need the form to reload the page on submit, which it currently does.

thanks.
