Rails spinoffs - Aug 2006 - Tricky Question: FileUpload + Display Update

Hi,

I have a form with:
- Simple fields like: <input type="text" />
- Files:  <input type="file" />

When I submit my form, I want to toggle input file and display a
progress bar. So
- I submit my form to an hidden IFrame
- I display progress bar (a div)

To update progress bar I start a PeriodicalExecuter then send a JSON
request to get
field status. But It doesn''t works ! :-(

I think my file are sent from the current page to the server (even if
the response will be displayed in IFrame). So my Ajax request is
freezed and wait end of upload.

What should I do ?
Can i ask my Iframe to send ajax request instead of current page ?
Should I use a third IFrame to handle progress ?

Best Regards,
Jp

Hi all,

In Scriptaculous for, say, the following tree:

ac_page_content_1
ac_page_content_2
 -> ac_page_content3

Once serialised and posted to the server (PHP) the $_POST array looks like
this:

Array
        (
            [0] => ac_page_content_1
            [1] => Array
                (
                    [0] => ac_page_content_3
                )
        )

This means that I have no way of knowing what the parent of
ac_page_content_3 is. 

The work-around I found was to change Sortable._constructIndex to;

if (node.id) index = ''['' + node.id + ''|'' +
node.position + '']'' + index;

So the resulting array is:

Array
        (
            [ac_page_content_1|0] => ac_page_content_1
            [ac_page_content_2|1] => Array
                (
                    [[ac_page_content_3|0] => ac_page_content_3
                )
        )

So at least I can tell from the key what the parent is.

Was wondering is anyone else had run into this, and what solutions you had
found?

Cheers,

Leon
