Re: File Chooser dialog needed
Thanks for the response.
I have a similar requirement for upload tooo. I want to make a Browse
button, which accepts folder locations, and uploads all the files in that
location. uploading the data from the file is fine... i can handle
but how to create a button, which accepts folder locations of both client
system and server system
?

Re: File Chooser dialog needed
Posted by Jeremy Thomerson <je...@wickettraining.com>.
Again, you can't do this in a standard HTML form. For something like this,
you will need to use something like an applet. Put simply, the browser does
not give you folder locations, and even if it did, your server couldn't list
or grab files from the client's folder. And, the browser won't
automatically upload an entire folder of anything. HTML has a file input
only for files - not directories. Allowing anything different would be a
big security risk.
As far as letting them choose where to save it on the server - why would you
do this? You can accomplish this by creating or using some sort of browse /
select component, but this is typically a bad idea - why do you want to give
a user access to your server file system over a webapp? It might be good to
go back and look at your real requirements and evaluate what MUST be done,
and then how best to accomplish it. (note - there may be certain use cases
where you do need to do this, but they are very rare, and almost
non-existent on a public app - which this may not be)
Anyway, hope this helps.
