I've been searching about this topic for two days, here is the situation...

After a user selects a file, on the form there are a couple fields needs to be passed to the script that uploads the file... I've been trying everything that is on the net about this, on all the events but nothing...

here is the code

$(function()
{
$("#file_upload").uploadify(
{
uploadLimit : 1,
method : "post",
multi : false,
auto : false,
fileTypeDesc : "Image Files",
fileTypeExts : "*.gif; *.jpg; *.png",
swf : "uploadify.swf",
folder : "upload_files",
uploader : "upload_images_controller.php",
onSelect : function(event,data)
{
$("#file_upload-button").hide();
$("#selected").val("yes");
}
});
});


Then on my Form:








Now if I add this on my javascript

$("#my_submit").click(function()
{
$('#file_upload').data('uploadify').settings.formData = {'sizes' : $("#sizes").val(),'member_id' : $("#member_id").val()};
$("#file_upload").uploadify("upload");
}

Does not do anything...

if I do the same on

onSelect : function(event,data)
{
$("#file_upload-button").hide();
$("#selected").val("yes");
$('#file_upload').data('uploadify').settings.formData = {'sizes' : $("#sizes").val(),'member_id' : $("#member_id").val()};
}

does not do anything either...

Now if instead of that

I do

onSelect : function(event,data)
{
$("#file_upload-button").hide();
$("#selected").val("yes");
$("#file_upload").uploadifySettings("scriptData", {"sizes" : $("#sizes").val(),"member_id" : $("#member_id").val()});
}

I got an error

Uncaught TypeError: Object [object Object] has no method 'uploadifySettings'

So basically the idea of passing extra parameters dynamically does not work...

Please advice what to do
