Summary	0025464: Enforce max-filesize in dropzone to alert and drop big files before form submission
Description	Seems like the option for max-filesize in Dropzone upload does nothing. I can submit any file but if the size is big enough, it's silently ignored I expect some kind of verification or notification from the client side before the file is uploaded.
Tags	No tags attached.

cproensa 2019-02-09 15:28 developer ~0061470	There is a message that appears when the cursor hovers over the file box. I've never realized that existed, after the years, so it's a good indication that this could be improved.

cproensa 2019-03-05 16:43 developer ~0061634	I have update the summary to better reflect the implemented changes.

MantisBT: master cb23a6e1 2019-02-09 15:36 cproensa Committer: atrol Details Diff	Reject files in client side Dropzone Catch the event for file added and check the file size to be under the maximum allowed size for uploads. If file is bigger, a warning message is shown and the file is rejected. Change how the max_file_size is passed to client, so that now we have the exact value in bytes to compare, even though Dropzone will still be configured with an aproximation in MiB.
