PHP form via email

I am trying to submit details via email using php, it has worked before for some reason it is not working now, can someone please help me as i have looked through it so many times and could not find the problem, thank you

Code:

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html> <body> <form action="welcome.php" method="post"> Name: <input type="text" name="name" /> Number: <input type="text" name="number" /> Email: <input type="text" name="email" /> Message: <input type="text" name="message" /> <input type="submit" /> </form> </body> </html>

PHP Code:

<?php if(isset($_POST['email'])) { /* subject and email variables */ $email_to = "someone@example.com"; $email_subject = "Contact Form"; ?> <html> <head><title> Test </title> </head> <body> <?php function died($error) { // your error code can go here echo "We are very sorry, but there were error(s) found with the form your submitted. "; echo "These errors appear below.<br /><br />"; echo $error."<br /><br />"; echo "Please go back and fix these errors.<br /><br />"; die(); } // validation expected data exists if(!isset($_POST['name']) || !isset($_POST['email']) ) died('We are sorry, but there appears to be a problem with the form you submitted.'); /* collect data variables */ $name = $_POST['name']; // required $number = $_POST['number']; // not required $email_from = $_POST['email']; // required $comments = $_POST['comments']; // not required $error_message = ""; $email_exp = "^[A-Z0-9._%-]+@[A-Z0-9.-]+\.[A-Z]{2,4}$"; if(!eregi($email_exp,$email_from)) { $error_message .= 'The Email address you entered does not appear to be valid.<br />'; } $string_exp = "^[a-z .'-]+$"; if(!eregi($string_exp,$name)) { $error_message .= 'The Name you entered does not appear to be valid.<br />'; } if(strlen($error_message) > 0) { died($error_message); } $email_message = "Contact Form details below.\n\n"; function clean_string($string) { $bad = array("content-type","bcc:","to:","cc:","href"); return str_replace($bad,"",$string); } $email_message .= "Name: ".clean_string($name)."\n"; $email_message .= "Contact Number: ".clean_string($number)."\n"; $email_message .= "Email: ".clean_string($email)."\n"; $email_message .= "Comments: ".clean_string($comments)."\n"; // create email headers $headers = 'From: '.$email_from."\r\n". 'Reply-To: '.$email_from."\r\n" . 'X-Mailer: PHP/' . phpversion(); $headers .= "Content-type: text/html\r\n"; @mail($email_to, $email_subject, $email_message, $headers); ?> <h2> Thank You </h2> </body> </html> <? } ?>
