Php form problem

[edsmiths]

Hi there,

I'm trying to use a php script to send a form through an html page.

I've followed this tutorial: [ame="http://www.youtube.com/watch?v=o4acVCCbJcI"]AJAX Form Submission To Email - YouTube[/ame] and used the author files (php code below).

I've managed to configured the html properly but get always this error:

There was an Invalid JSON:
Warning: Cannot modify header information - headers already sent by (output started at /home/user/public_html/mysite.com/feedback.php:1) in /home/user/public_html/mysite.com/feedback.php on line 43
error due to a parsererror condition.

Is there anything wrong with the code or is something in the hosting configurations?

Beside this example... could you please point me a tutorial with simple jquery/ajax/php script to send a form.

Thanks in advance,
Ed

<?php 
sleep(2);
//Sanitize incoming data and store in variable
$name = trim(stripslashes(htmlspecialchars($_POST['name'])));	  		
$email = trim(stripslashes(htmlspecialchars($_POST['email'])));
$message = trim(stripslashes(htmlspecialchars($_POST['message'])));	    
$humancheck = $_POST['humancheck'];
$honeypot = $_POST['honeypot'];

if ($honeypot == 'http://' && empty($humancheck)) {	
		
		//Validate data and return success or error message
		$error_message = '';	
		$reg_exp = "/^[a-zA-Z0-9._%+-]+@[a-zA-Z0-9-]+\.[a-zA-Z.]{2,4}$/";
		
		if (!preg_match($reg_exp, $email)) {
				    
					$error_message .= "<p>A valid email address is required.</p>";			   
		}
		if (empty($name)) {
				   
				    $error_message .= "<p>Please provide your name.</p>";			   
		}			
		if (empty($message)) {
					
					$error_message .= "<p>A message is required.</p>";
		}		
		if (!empty($error_message)) {
					$return['error'] = true;
					$return['msg'] = "<h3>Oops! The request was successful but your form is not filled out correctly.</h3>".$error_message;					
					echo json_encode($return);
					exit();
		} else {
				
	//send to an email
$to = 'myemailaddress.com';
$from = 'validemailinthehost.com';
$headers = 'MIME-Version: 1.0' . '\n';
$headers .= 'From: $from' . '\n';
$subject = 'Contact Form Submission\n';
$body = 'Name: ' .$name . '\n';
$body .= 'Email: ' .$email . '\n';
$body .= 'Message: ' .$message . '\n';

	//send email and return a message to the user
	if(mail($to, $subject, $body, $headers)) {

	$return['error'] = false;
			$return['msg'] = "<p>Thanks for your feedback " .$name .".</p>"; 
			echo json_encode($return);
			
			} else {
	
		$return['error'] = true;
		$return['msg'] = "<h3>Oops! There was a problem sending your email. Please try again.</h3>";	
		echo json_encode($return);
		}
	

	}
	
	} else {
	
	$return['error'] = true;
	$return['msg'] = "<h3>Oops! There was a problem with your submission. Please try again.</h3>";	
	echo json_encode($return);
}
	

?>
