Play framework multiple file upload

I try to upload multiple files with one request but it always error, My view code:

<input type="file" name="files[]" multiple>

And:

public static void doUpload(File[] files) {
    File dir = new File(Play.applicationPath+File.separator+"public"+File.separator+"uploads");
    if (!dir.exists()) {
        dir.mkdirs();
    }

    boolean success = files.renameTo(new File(dir, files.getName()));
    if (!success) {
        renderText("{'success':'true', 'msg':{'url':'"+files.getName()+"'}}");
    } else {
        renderText("{'success':'true'}");
    }
}

If I use single file upload with <input type="file" name="files"> and parameters in controllor using File files, then it works fine.

thank you.

This works fine in Play 1.2.5 with the multiple tag in <input type="file" name="files" multiple>. The only problem I see with the original posters code was name="files[]" which should have been name="files"

It may have been the case that there was also a bug in an earlier version of Play, but this just worked for me (I selected 50 files with one file input)

If you have multiple inputs with the same name, the controller will receive those files with the given name as an array, e.g.

Controller:

public static void upload(File[] files) {
    ...
}

View:

#{form @upload(), enctype:'multipart/form-data'}
<input type="file" name="files">
<input type="file" name="files">
<input type="file" name="files">
<input type="submit" value="Upload" />
#{/form}

You can always add a bit of javascript to allow the user to add additional inputs on the client side
