Php Js Ajax I need some assistance - php

Question

I am trying to create a social dating site and I have my problem in the Add as Buddy Button. When you click it, my site should be sending the uid of the sender (from_uid) and the uid of the receiver (to_uid) to the database. It sends out the from_uid successfully but the to_uid always sends 0.
PHP
<div class="member" data-user="<?php echo $member['xmpp_user']; ?>" data-uid="<?php echo $member['uid']; ?>">
<input type="hidden" id="hiddenuid" value="<?php echo $member['uid']; ?>">
<img src="https://s3.amazonaws.com/wheewhew/user/<?php echo $member['uid']; ?>/photos/<?php echo $member['profile_pic']; ?>" />
<div class="member_name"><?php echo $member['firstname']." ".$member['lastname']; ?></div>
<div id="addbutton"><button type="submit" class="add"> Add as Buddy </button></div>
</div>
Javascript
<script type="text/javascript">
var BOSH_SERVICE = 'http://wheewhew.com:5280/http-bind';
var connection = null;
var xmpp_user = "<?php echo $xmpp_user; ?>#wheewhew.com/default";
var xmpp_pass = "<?php echo $xmpp_password; ?>";
var uid = "<?php echo $uid; ?>";
$(document).ready(function () {
$('#btn-logout').click(logout);
$('.add').click(addBuddy);
connectXMPP();
//updateLastSeen();
});
</script>
jabber.js
function addBuddy(){
var xmpp_user = $(this).parent().attr('data-user')+'#wheewhew.com/default';
var to_uid = $(this).parent().attr('data-uid');
$.ajax({
type: "POST",
url: "./ajax/addBuddy",
data: "from_uid="+uid+"&to_uid="+to_uid,
success: function(data) {
var ret = eval('('+data+')');
if(ret.status == 'success'){
connection.send($pres({to:xmpp_user,type:'subscribe'}).tree());
}
}
});
}

Answer 1

Your addBuddy function doesnt have a reference for what $(this) is. Try this out:
$('.add').click(function(){
addBuddy($(this));
});
And then in your function:
function addBuddy($btn){
var xmpp_user = $btn.parent().attr('data-user')+'#wheewhew.com/default';
var to_uid = $btn.parent().attr('data-uid');
// ajaxy stuff
}
That should help. At the very least, we can continue the discussion here rather than in the comments for the OP.
