Having issues sending upload values to hidden field - php

Question

i have been trying so hard to fix my issue. I've looked on google loads and attempted the fixes but i am having no luck at all.
$(function() {
$("#listing_pic").uploadify({
height : 30,
swf : 'uploadify/uploadify.swf',
uploader : 'uploadify/uploadify.php',
width : 120,
fileExt : '*.jpg; *.jpeg; *.JPG; *.JPEG;',
checkExisting : 'uploadify/check-exists.php',
simUploadLimit: 2,
fileSizeLimit : '4MB',
auto : true,
multi : true,
onComplete : function(event,queueID,fileObj,response,data) {
$('#hiddenlistingpic').val(response);
},
});
});
Im trying to get Uploadify to upload my image to my server (which works fine) but then send the filename to the hidden field so that i can post the data into my database update class. It's giving me a headache, and im more than certain its a simple fix.

from here: https://stackoverflow.com/a/3466188/1253747
$(function() {
$("#listing_pic").uploadify({
height : 30,
swf : 'uploadify/uploadify.swf',
uploader : 'uploadify/uploadify.php',
width : 120,
fileExt : '*.jpg; *.jpeg; *.JPG; *.JPEG;',
checkExisting : 'uploadify/check-exists.php',
simUploadLimit: 2,
fileSizeLimit : '4MB',
auto : true,
multi : true,
onComplete : function(event,queueID,fileObj,response,data) {
$('#hiddenlistingpic').val(fileObj.name);
},
});
});
or from the uploadify docs, there seems to be many other ways to get it:
'onUploadSuccess' : function(file, data, response) {
$('#hiddenlistingpic').val(file.name);
}
same thing can be done with the onuploadcomplete.
or is there anything else that i am missing?
