File Upload From Forms (something like Dojo have)

Dojo (AJAX Framework) has something like IFrameIO which allows to
upload files from form to server without reloading page, but the whole
my page right now is written using prototype framework. Does prototype
has something that I could use to get the same result? (Before I start
editing my few thousands of code lines)

Re: File Upload From Forms (something like Dojo have)

Dojo uses the iframe trick IIRC. You could look into:

http://sean.treadway.info/articles/2006/05/29/iframe-remoting-made-easy
http://sean.treadway.info/demo/upload/
http://www.ruby-forum.com/topic/113636

I prefer to use SWFUpload, because of its many clientside filtering  
abilities:

Also look into this should you use SWFUpload: http://

Re: File Upload From Forms (something like Dojo have)

Am I wrong or SWFupload send all files as octet-stream so you are not  
able to get mime type in a rails application?

Re: File Upload From Forms (something like Dojo have)

I feel its important to point out that prototype isn''t like dojo.

From what I briefly read (to get a proper explaination) is that dojo is a
toolkit. That is ''widget'' (bits of code you can drop in to do
functionality)
and ''event'' based,
whereas prototype (which i am more familiar with) is more of a framework
which extends Javascript to allow you to do some very cool flexible
manipulations of data and acomplish tasks much quicker than you would if you
were writing normal base javascript.
Scriptaculous is an addon to Prototype (in that it uses prototype internally
and is designed to go with it) that offers a few widget style
functionalities, such as drag and drop sorting and autocomplete text boxes.

So the original question of can I do iframe/ajax dynamic file uploads with
prototype?
Sure, if you code something to use the prototype methods/dom extensions to
save the amount of code you have to write.
As a prebuilt object you can just add into your page? Nope.

Prototype has tonnes of features to help you here, such as the new Element
constructor (actually i think this might be 1.6, not 1.5.1), but you can use
the scriptaculous Builder syntax..
to Create the iframe, and attach events to button presses/image clicks to
invoke your fileupload dialog.
I haven''t read too much about how to do one of these uploads recently
but as
far as I know, a dummy webpage with a standard fileupload form is put into
an iframe, which is manipulated via javascript via cross frame scripting to
invoke the file dialog and submit the form.
This iframe submits to a server script and returns the information about the
file to the calling window/frame which then notifies the user their
requested upload has completed.

As for Sebastien''s question, someone else will need to answer that.

Re: File Upload From Forms (something like Dojo have)

After big pane for a while in my ass I managed to make it work with
Dojo, but I started to think do I really want it? And the answer is
no. Dojo is huge, it''s more complex and I must rely on it''s
methods,
while on prototype almost everything is done by myself.

I have two ideas left, I will try to make it with prototype with
iframe or do it the easiest way, just plain upload script and small
pop-up window. I don''t know why, but I really don''t want to
have
something huge like Dojo in my source code. In some way it reminds me
JAVA/C#.

Re: File Upload From Forms (something like Dojo have)

If you have a form like so :

<form target="uploadDiv"
action="http://path/to/handler">
  <input type="file" name="filename" />
  <input type="submit" value="Submit" />
</form>

<iframe name="uploadDiv" style="width:0px; height:0px"
url="_blank" />

Then, when the submit button will be pressed, your page will not
refresh, but it''s the iframe that will be used to send the data from
the form to the action url to the server.

For the rest, look on how to send javascript to an iframe to talk with
the javascript in you Web app. Or set up a timer that will look for
any change in the iframe...

Do not make the iframe invisible. Some browser don''t like that. Rather
use a 0 sized iframe (like suggested).

I could send you a script I wrote to send multiple files
asynchronously using a PHP script and an iframe (with a little control
over the file queue ;  pause, stop, restart, etc.) But the code is not
well documented (though not really hard to understand). I just went on
with SWFUpload instead as I needed something to upload multiple files
with progress bar all on client side.

Cheers.

Re: File Upload From Forms (something like Dojo have)

Yanick, I really would like to see your code, I am always open for new
ideas how to make something. You know my email (you should see it, I
think). And don''t worry, I will read the code... :)

Re: File Upload From Forms (something like Dojo have)

Hello everyone.

I have an upload page that worked perfectly using prototype 1.4, but  
fails with 1.5 and 1.5.1. I am not sure how to troubleshoot the  
failure. I have set up a test page to demonstrate the problem.

http://clearimageonline.com/pages/start/prototypetests/index.html

Any suggestions?

Thanks,

Terry Riegel

Re: File Upload From Forms (something like Dojo have)

Sorry for the short description earlier. I was in a rush. Here is  
what is happening.

In Version 1.4 It works in all browsers. By "it works" I mean it will.
1. Upload a file
2. Show a progress bar while uploading

In version 1.5 and 1.5.1 it seems to always fail to produce a working  
progress bar, and in some os/browser configurations it doesn''t upload  
at all.

I tried to review the changelog for prototype, but it didn''t go back  
to 1.4. I would love to use at least version 1.5 for this and other  
projects but am not versed enough to determine how to troubleshoot  
this one.

Thanks for any help.

I thought about progress bar, and as I can see it is possible to make
using only iframe and without any AJAX at all. I will be trying to
make this work today.

Re: File Upload From Forms (something like Dojo have)

Hey Terry,

        I took a quick look at your upload form.  First and foremost,
for debugging JS Application gotta get the Firebug.  I was looking at
the script and I noticed there was only one request to the server to
get progress with the Prototype 1.5 versions, so maybe something has
happened with Ajax.PeriodicalExecuter?  The 1.4 Script did make two
requests while i was uploading a windows sample image so it displayed
0 and 70%.

Cheers
