I do not think we've ever supported this - looks more like a hack. Why not simply instantiate several Plupload uploaders? Otherwise you can instantiate Plupload into a specific container element by passing container's id (or a container itself) as a value for container option, and then search for an Plupload structures within it after upload finishes initialization.

uploader.id doesn't correspond to browse_buttons id in Plupload 2, they are just an arbitrary unique ids.

Plupload2 is not working on IE8 without flash (html4 on IE8).  I just downloaded the latest build and still not working.  When I switch the plupload script file to 1.5.7 it is working on IE8 with html4.  I'm not getting any errors, it just fails to initialize.  The PostInit event never fires.

We had a slight twist in the logic with the previous build, but now we came to a conclusion that while it has some sense, drawbacks are far more dramatic, so we bailed out. Could you guys try the latest nightly and see if you still get any unexpected errors?

Check Plupload Github

If i am not wrong drop_element is could be your element ID.
[drop_element] String|DOMElement
id of the DOM element or DOM element itself to use as a drop zone for Drag-n-Drop.

example:
<div id="mydropzone"><p>You browser doesn't have Flash, Silverlight, Gears or HTML5 support.</p></div>
drop_element : 'mydropzone'

Could you please add an option for a folder select button ? (enable not only dropping folders .. )
That would open a folder select dialog
like the one in mega.co.nz

Thanks !

Hello, the version taken from GitHub always shows me runtime HTML5 (which I have on the first place of runtimes) even in IE7-9 and Safari 5.1 for Windows. How is it possible? Thanks a lot for reply.

Hi Davit, I mean this:

that.uploader.bind('Init', function (up, params) {
                alert(params.runtime);
                }
});

In Ie 7 - 9 it even really chunks the upload (but maybe it's because of Silverlight -  I use html, silverlight runtimes in this order). In Safari 5.1 for Win. it also shows me html5 but the upload is not chunked.

Thanks.

Thanks for reply Davit, now I see how it should work, but it does not work. If I set required_features to true and have 'html5,silverlight' specified in runtime, I get correctly html5 value for ie10, but always null value for ie7-9 (there should be silverlight instead of null). If I set runtime only to 'silverlight', I get always null value for ie7-ie10. I use windows 8 and have silverlilght installed. Do you have any idea why is it so?

Thnaks many times.

In Safari 5.1 I get null too when i have required_features set to true. I've just tried this:
http://jsfiddle.net/gh/get/jquery/1.9.1 … re/bundled

and I am even more confused. In Safari 5.1 it works only when I have not set required_features to true, but in ie10 it does not work at all. In FF, Chrome and Opera it's OK even when I set required_features to true.

I send my config also:

                    runtimes: 'html5,silverlight'
                    ,
                    browse_button: that.$browseButton[0]
                    ,
                    container: $element.attr("id")
                    ,
                    drop_element: that.$dropZoneElement[0]
                    ,
                    dragdrop: true
                    ,
                    chunk_size: '1mb'
                    ,
                    required_features: true
                    ,
                    //required_features: 'chunking'
                    //,
                    max_file_size: '2gb'
                    ,
                    multipart: true
                    ,
                    multipart_params: {
                        "path" : this.options.path.join("\\")
                    }
                    ,
                    url: this.options.url
                    ,
                    flash_swf_url: that.jsFileLocation + 'Moxie.swf'
                    ,
                    silverlight_xap_url: that.jsFileLocation + 'Moxie.xap'

Thanks a lot for advance...

Still does not work. If there is required_feauters set to true, it does not work. As I said even when I tested via the link I sent you it did not work and there was no dragdrop. Anyway thanks for your advice, I removed that dragdrop in my config.
In fact it is all not so big problem for me becasuse I don't have to use required_features set to true eventually. But I am still confused why in ie7-9 it shows me html5 than. It should show Silverlight. Am I right?

Thanks.
