in set.php:

<?php

session_start();
$_SESSION['value'] = $_POST['value'];

?>

in the non-form form page.php:

<?php session_start() ?>
<html>
<head>
<script type="text/javascript"
  src="http://ajax.googleapis.com/ajax/libs/jquery/1.3.2/jquery.min.js"></script>
<script type="text/javascript">
function setVal()
{
  var val = jQuery('#value').val()
  alert('Setting the value to "' + val + '"')
  jQuery.post('set.php', {value: val})
  alert('Finished setting the value')
}
jQuery(document).ready(function() {
  setTimeout('setVal()', 3000)
})
</head>
<body>

<form>
<input id="value" type="text" name="value" value="value">
<input id="value2" type="text" name="value2" value="value2">
</form>

</body>
</html>

this will record the value (after a 3 second delay)

test it in test.php:

<?php

session_start();
echo '<pre>';
echo htmlentities(var_export($_SESSION, true));
echo '</pre>';

?>

now it's in your session with no form submit

Using jQuery and PHP

The HTML:

<input type="text" id="autosend" />

The JavaScript

$(function(){
   $('#autosend').blur(function(){
       $.post('receiver.php',{fieldval:$(this).val()},function(response){
          alert(response);
       });
   })
})

The PHP

$_SESSION["somename"] = $_POST["fieldval"];
echo $_SESSION["somename"];

Now, whenever input field looses focus, the session variable will be updated with the current value.

I suppose your best bet is to set up a separate PHP script that is called upon via Javascript with the input field information in the query string (ajax.php?key=value) and stores that information to a $_SESSION variable.

That PHP would probably look something like this:

session_start();
foreach ($_GET as $key => $value)
   $_SESSION[$key] = $value;
