Multiple File Upload in Grails
file-upload, grails, jquery
Solution
Actually I figured it out. There is only one `input[type=file]` in the form and if I select several files they are not sent on the same request. The `query-file-upload` script sends as many POST requests as there are files. That's why `request.getFileNames()` only gives me one entry each time. I managed to create my plugin, it will be published soon. Watch out for http://grails.org/plugin/bootstrap-file-upload.
Problem
I'm trying to integrate the excellent jquery-file-upload from blueimp into Grails 2.0 and to write a new plugin for that. I know there is already a plugin, but it doesn't use resources and it hasn't been updated for 9 months, and jquery-file-upload has changed a lot in that time. So I put all of the files of the distribution in my plugin, and now I'm trying to write a controller action that can handle the upload. The problem is that `request.getFileNames()` only gives me one `files[]` entry and I don't know how to retrieve the 3 individual files I am uploading. How do you handle the files sent by an input like this: `<input type="file" name="files[]" multiple>`?
