Hi UncleCheese,

That doest seemed to have helped unfortunately. This is a truly confusing problem.

Where is the refresh function so I can try debug inside there? I have looked inside FileUploadField and MultipleFileUploadField as both have a refresh() but if I try to print something to the browser, it doesnt show?

Look at line 42 or uploadify_init.js. It runs an ajax call to /YourFormField/refresh/:

                     $.ajax({
                        url: $e.metadata().refreshlink,
                        data: {'FileIDs' : ids.join(",")},
                        async: false,
                        dataType: "json",
                        success: function(data) {
                           $preview.html(data.html);
                        }
                     });

Make sure that's running!

FYI, last time I saw this, the success function wasn't firing, despite the 200 response code. I eventually figured out that it had something to do with the content negotiator. It was bizarre.

But to test it, you can put an error handler in..

error : function(jqXHR, textStatus, errorThrown) {
console.log(textStatus, errorThrown);

}

Hmm, I put the error handler in, but it doesnt throw anything. Where exactly should I put it? I think I have it in the wrong place...

I put this in the ajax call:

success: function(data) {
alert(data);
$preview.html(data.html);
}

and data comes back as null... So it is definitely running the function, but it isn't responding with the files?

OK, that's actually a good thing because it probably means you can debug within PHP.

Look at UploadifyField::refresh(). There may be different refresh() functions for each descendant of UploadifyField, so make sure you check those first. I believe FileUploadField and MultipleFileUploadField, for instance, have their own refresh() handlers.

Find the right refresh() function and just start adding echo statements in the function, leaving your alert(data) statement in there. (console.log() is probably a better option for you, since it will show the contents of the returned object).

Start by putting an echo statement at the first line of the function and work your way down until you figure out why the return is coming back null, and let me know the results!

Ok making progress here. I found the correct refresh function - its MultipleFileUploadField::refresh(). I put an echo right at the very start of the function, but i was still getting null returned. So I copied the URL from the request into the browser and still got null. See here:
http://rocna.com/admin/EditForm/field/MediaImages/UploadifyForm/field/UploadedFiles/refresh?SecurityID=3751a3c35bcec9609407f090f86d285e97146dcc&ctf[MediaImages][start]=0&ctf[MediaImages][per_page]=10&ctf[MediaImages][showall]=0&ctf[MediaImages][sort]=SortOrder&ctf[MediaImages][sort_dir]=&ctf[MediaImages][search]=&ctf[MediaImages][filter]=&ctf[MediaImages][view]=grid&ctf[MediaImages][imagesize]=100&FileIDs=198

However, if I remove all the request data and just browse directly the function, like so:
http://rocna.com/admin/EditForm/field/MediaImages/UploadifyForm/field/UploadedFiles/refresh

I get a response along these lines (you can see my echo 'hello' at the start)

hello{"html":"
Attached files<\/div>\n
\n\t\n\t
\n\t\t\n\t\t\tNo files attached\n\t\t\n\t<\/div>\n\t\n<\/div>\n\n
\n\t\n<\/div>","success":"Added files successfully."}

Interesting.... now the url works, even with everything there...

http://rocna.com/admin/EditForm/field/MediaImages/UploadifyForm/field/UploadedFiles/refresh?SecurityID=3751a3c35bcec9609407f090f86d285e97146dcc&ctf[MediaImages][start]=0&ctf[MediaImages][per_page]=10&ctf[MediaImages][showall]=0&ctf[MediaImages][sort]=SortOrder&ctf[MediaImages][sort_dir]=&ctf[MediaImages][search]=&ctf[MediaImages][filter]=&ctf[MediaImages][view]=grid&ctf[MediaImages][imagesize]=100&FileIDs=198

But I havent changed anything since, so its intermittent??

UPDATE: Ok so I see a relation to what is causing the problem. This url works:
http://rocna.com/admin/EditForm/field/MediaImages/UploadifyForm/field/UploadedFiles/refresh?FileIDs=198
This one doesnt:
http://rocna.com/admin/EditForm/field/MediaImages/UploadifyForm/field/UploadedFiles/refresh?FileIDs=199

The file ID 198 DOESNT exits in the File table in the database, but 199 does... However, I cant see why that would cause my echo to not be returned, when its right at the start of the function:

public function refresh() {
      print_r('hello');
      ContentNegotiator::disable();
      $count = 0;
      $before = is_array($this->Value()) ? sizeof($this->Value()) : 0;
      if(isset($_REQUEST['FileIDs'])) {
         $ids = explode(",",$_REQUEST['FileIDs']);
         if(is_array($ids)) {
            $this->setValue($ids);
            $count = sizeof($ids) - $before;
         }
      }   
      return Convert::array2json(array(
         'html' => $this->renderWith('AttachedFiles'),
         'success' => sprintf(_t('Uploadify.SUCCESSFULADDMULTI','Added files successfully.'), $count)
      ));
   }
