Multiple File Upload in Grails

Question

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

Answer 1

request.getFileNames returns an array - you can iterate over this array to obtain all the files. The example is already there on the plugin description.

def all = request.getFileNames()
all.each {name ->
   def file = request.getFile(name)
}

This should give you all the files that were uploaded.

Answer 2

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.
