Multi file upload and preview before uploading

Post by peopleopinion » Sun Nov 10, 2013 1:25 am

What about to add a new feature to upload multi file and (if they are images) to see their preview BEFORE uploading them?
Seeing a preview of files that support the preview is useful to correct the selection of files queued for upload BEFORE the upload process itself so if there is some wrong file in the queue it can be removed before loosing time to upload it and delete it after uploading.

Of course the preview can be activated or not on the fly by the user so he has the choice of what to do if it is not sure of the selection he has done.

Previews / thumbnails of picture attachments are created server-side, which implies to fully upload the files. So I guess you just want your local pictures to be displayed before starting the upload?

Well... Yes and No... The following is an extraordinary example of what I mean:
http://blueimp.github.io/jQuery-File-Upload/

As you can see there are more demo examples that work a bit differently but final results are good except for the Basic Basic Plus versions that I don't like at all. In fact I like the Basic Plus UI,
AngularJS and jQuery UI that I think has the best functionalities.

As you can see it is enough to select more files or images at once. For allowed images a thumbnail preview is showed in few instants after selection and before uploading.
To see how it works you don't need to upload anything but I tried it in a test web space of mine and it works great with a lots of images files: I tried it with about 50 image files not too big because the local process of previewing can slow down in my local pc that a bit old and slow. The preview of first files start immediately and took about 8-10 secs to complete. After the preview has showed it is possible to: start upload files just one by one or all at once or delete unwanted files and upload remaining. It is possible to stop upload also. Support drag and drop from the basic plus. I think it is an interesting piece of code.

Of course I don't know which features are already implemented in 3.1 phpbb core that seems to be pretty better than 3.0.11 I'm using. But I think it will be a real good news to see something like jqfu there.

Thanks for reading
