[jQuery] jQuery Edit In Place Help


Hello All,
I am working to get this plugin
http://15daysofjquery.com/edit-in-place-with-ajax-using-jquery-javascript-library/15/
working. I can successfully edit in place text, but I would like to
take a php variable from my editing page and pass it to my updating
the database page. Unfortunately I don't know javascript well enough
to do this. The variable is the same for each div that is edited.
Here is my code:
Edit page:
<html>
<head>
<script src="jquery.js" type="text/javascript"></script>
<script src="jqueryEIP.js" type="text/javascript"></script>
</head>
<body>
<? $date = "1176274800"; ?>
<div class="entry">
Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do
eiusmod tempor incididunt
</div>
</body>
</html>
jqueryEIP.js:
$(document).ready(function(){
    $("span").each(function(i){
        setClickable(this, i);
    })
});
function setClickable(obj, i) {
    $(obj).click(function() {
        var textarea = '<div id="edit"><textarea rows="2" cols="60">'+$
(this).html()+'</textarea>';
        var button     = '<div><input type="button" value="SAVE"
class="saveButton" /> OR <input type="button" value="CANCEL"
class="cancelButton" /></div></div>';
        var revert = $(obj).html();
        $(obj).after(textarea+button).remove();
        $('.saveButton').click(function(){saveChanges(this, false, i);});
        $('.cancelButton').click(function(){saveChanges(this, revert, i);});
    })
    .mouseover(function() {
        $(obj).addClass("editable");
    })
    .mouseout(function() {
        $(obj).removeClass("editable");
    });
}//end of function setClickable
function saveChanges(obj, cancel, n) {
    if(!cancel) {
    var t = $(obj).parent().siblings(0).val();
    $.post("updatenotes.php",{
     content: t,
     n: n,
    },function(txt){
        alert( txt);
    });
}
    else {
        var t = cancel;
    }
    if(t=='') t='(click to add text)';
        $(obj).parent().parent().after('<span class=regular>'+t+'</
span>').remove();
        setClickable($("span").get(n), n);
    }
Just to recap, how do pass $date to updatenotes.php using POST?
Thank you for any help!
