and php:

    <?php  if(isset($_post['email'])) {  $email_to = "mymail";   $email_subject = "";      function died($error) {     // edw mpainei mhnuma p tha emfanisei se periptwsh error     echo "we sorry, find error(s) in form<br/>      <br/>";     echo $error."<br /><br />";     echo "please go , fix these errors.<br /><br />";     die();   }     if(!isset($_post['name']) ||     !isset($_post['email']) ||     !isset($_post['message'])) {           }  $name = $_post['name'];  $email_from = $_post['email'];  $message = $_post['message'];  $error_message = ""; $email_exp = '/^[a-za-z0-9._%-]+@[a-za-z0-9.-]+\.[a-za-z]{2,4}$/';     if(!preg_match($email_exp,$email_from)) {        $error_message .= '<br>the email address entered not appear   valid.<br />';    }    $string_exp = "/^[a-za-z .'-]+$/";    if(!preg_match($string_exp,$name)) {    $error_message .= '<br>the first name entered not appear   valid.<br />';  }    if(strlen($message) < 2) {    $error_message .= '<br>the comments entered not appear valid.<br />';  }     if(strlen($error_message) > 0) {    died($error_message);     }        $email_message = "form details below.\n\n";  function clean_string($string) {   $bad = array("content-type","bcc:","to:","cc:","href");   return str_replace($bad,"",$string);      }      $email_message .= "name: ".clean_string($name)."\n";     $email_message .= "email: ".clean_string($email_from)."\n";      $email_message .= "message: ".clean_string($message)."\n";     $headers = 'from: '.$email_from."\r\n".  'reply-to: '.$email_from."\r\n" .   'x-mailer: php/' . phpversion();   mail($email_to, $email_subject, $email_message, $headers);     ?>     <?php    }      die();    ?> 

when finish php contact form mailing code, @ moment code says:

die(); 

change to:

die('<meta http-equiv="refresh" content="0; url=http://example.com?bob=youruncle" />'); 

of course, change bob=uncle key=value want - nonsense string, or contact=sent, or whatever.

then, @ top of index.php file, add:

<?php      if ( isset($_get['bob'] ){         $message = 'contact form sent!';     }else{         $message = '';     } 

javascript/jquery page:

$(document).ready(function(){      var sendmsg = "<?php echo $message; ?>";     if (sendmsg.length){         alert(sendmsg);     }  }); //end document.ready 

or, more fancy:

$(document).ready(function(){      var sendmsg = "<?php echo $message; ?>";     if (sendmsg.length){         settimeout(function(){             $('body').append('<div id="thx" style="display:none;position:absolute;top:20%;left:30%;font-size:5rem;background:wheat;z-index:2;">thanks contacting us!</div>');             $('#thx').fadein(700,function(){                 settimeout(function(){                     $('#thx').fadeout(700);                 },3000);             });         },3000);     }  }); //end document.ready
