Multiple submit not working on component

[Miguel Lopes]

I'm using the "same name to all input type submits" technique. This is very nice because it avoids some js and works like a charm :-) 

In a regular controller the code works flawlessly. However when I try to put it in a controller, it fails:

status_form = FORM(_id='status_form')

for status in OPPTY_STATUS:

    btn = INPUT(_type='submit', _name='status', _value=status, _class='status_btn')

    status_form.append(btn)

if status_form.accepts(request.vars, session, formname='status_form'):

    # status_form.vars.status is None in component

    # status_form.vars.status corresponds to whatever submit was pressed in regular controller

...

It seems like the component mechanisms is ignoring the value of 'status'.

As an update, the issue remains with the following combinations:

* if input type='submit' and different names

* if input type='button', with or without different name attributes

However, input type='text' are present in form.vars.

For the interested a solution for usage in components is to use set a hidden input text field via the click event of each button.

I think this is a bug in the web2py in the form processing system. I
will fix it tonight.

well... it is a bug not not in web2py, in jQuery:

We cannot fork jQuery to fix this. Eventually they will fix it.

Thank you!

Importantly, although it is very convenient to have these values serialized, it is simple to get around this jQuery imposed limitation (bug).

jquery serialize also does not support type=file. If you have a way to
get around these, please let me know.

I've researched this a bit. Although I have not found an authoritarive source, the "problem" is that Javascript cannot access files on the desktop, the browser must do it. Thus, not supporting inout type=file is not a jQuery problem. It is possible to code around this, namely using iframe (any other?). Someone more knowledgable may confirm this.

Some interesting solutions are (untested):

http://valums.com/ajax-upload/    - a dedicated javascript script library

http://trentrichardson.com/2009/06/05/meet-jquery-iframer/    - a jQuery plugin

http://www.webtoolkit.info/ajax-file-upload.html      - a 1Kb Javascript file

Anyone has experience with these or other solutions?
