Subject Multiple file upload
Date Wed, 28 Sep 2011 08:39:46 GMT
Hi Gerald and Embperl users,

I've been interested in giving my users the option of uploading multiple 
files simultaneously, and the only/best option I was able to find up to 
now has been the swfupload Flash widget. However I now notice that 
people are starting to talk about doing this via HTML5, and I came 
across this interesting feature: You can add a "multiple" attribute to 
the upload button, e.g. <input type="file" multiple ...>. When I do 
this, my browser (Seamonkey 2.3.3 on Linux) does surprisingly allow me 
to select multiple files in the standard upload dialog. However I'm not 
sure if it's actually sending the files (it seemed to come back very 
quickly), and I don't seem to receive anything on the server side that 
makes much sense (my usual upload script ended up with a file of zero 
bytes). So I'm wondering if anyone knows whether this browser feature is 
actually working (i.e. do those files actually get transmitted somehow 
in one request) and if so, would it be possible to process them from 

Or, if pure HTML5 is the way to go, is this feasible with today's 
mainstream browsers, and again is it possible to process whatever comes 
in on the server side using the current Embperl? It would be really nice 
to be able to do this without resorting to Flash widgets.
