at the moment im using  AJAX tabs , but im using classic nonAJAX form actions. i have been told that for my script to work properly so that forms an be processed under each tab that i need to have it  completely AJAX.  so how can i chnage the code below so that it carries out the submittion to the db via ajax
<?php error_reporting(E_ALL);
require_once '../../../settings.php';
include "../../../info.php"; // sets username/id ect
$getuser = mysql_fetch_assoc(mysql_query("SELECT * from users where Username='$username'"));
$getuserprofile = mysql_fetch_assoc(mysql_query("SELECT * from profile where ID='" .
				$getuser['ID'] . "'"));
	  foreach($_POST as $field => $value) {
   if (($field != 'submit') && ((!$value) || (trim($value) == ''))) {
      $err .= "$field cannot be empty. <br>";
      $warnings[$field] ="required";
if (!$_POST["about_me"] || !preg_match("/^[a-zA-Z ]+$/", $_POST["about_me"])) {
   $warnings["about_me"] = " <label for=\"uname\" class=\"error\"><em>*</em>please only user words</label>";
           $count  = count($warnings);
if($count === 0)
if(array_key_exists('submit', $_POST))
$about_me = mysql_real_escape_string($_POST['about_me']);
$update = "UPDATE profile SET  about_me = '$about_me' WHERE ID='$id' ";
echo $update;
$result = mysql_query($update);
// Check result
// This shows the actual query sent to MySQL, and the error. Useful for debugging.
if (!$result) {
    $er  = 'Invalid query: ' . mysql_error() . "\n";
    $er .= 'Whole query: ' . $query;
  echo '			<p class="error">' . $message . '</p>' . "\n";
            if ($err){?>
      <div class="errors">
		<p align="center"><em>Oops... the following errors were encountered:</em></p>
		<div align="center"><?php echo $err; ?>	      </div>
		<p align="center">&nbsp;</p>
		<p align="center">Data has <strong>not</strong> been saved.</p>
       <?php } ?>
        <legend>About me</legend> 
        <div class="c1">
                <form  action='members/include/profiletab/hobbies.php' method="post" name="submit">
              <p><em><strong>Tell everybody a little bit about yourself...</strong></em></p>
                <textarea <? if (count($warnings) > 0){ if ($warnings['about_me']) echo "class=\"inputerror\""; }?> onKeyPress="return taLimit(this)" onKeyUp="return taCount(this,'myCounter')" name="about_me" rows="7" wrap="physical" cols="60">
<?php echo $getuserprofile['about_me']; ?><?php if (count($warnings) > 0){ echo $warnings["about_me"];} ?>
                <br />
                <br />
                You have <b><span id="myCounter">1000</span></b> characters remaining</p>
                <input type="hidden" name="submitted" value="1" />
              <input name="submit"  type="submit"  value="Submit" />
