Uploading multiple files

[Lakhi Calantoc]

Hello Ninja Team, Do you have other examples of upload functionality when uploading multiple files? using the DiskItemProvider class? Thanks!

Hi.

Here is a really quick example of how it can work. It assumes your input field for multiple files is called "upload".

    public Result upload(Context context) {

        try {

    for (FileItem fileItem : context.getParameterAsFileItems("upload")) {

                String fileName = FilenameUtils.normalize(fileName);

                File file = buildPath(fileName);

                if (file.exists()) {

                    throw new BadRequestException("File already exist");

                }

                FileUtils.forceMkdirParent(file);

                FileUtils.copyInputStreamToFile(stream, file);

                // For logging purpose : FileUtils.byteCountToDisplaySize(file.length());

    }

        } catch (IOException e) {

            throw new BadRequestException(e.getMessage(), e);

        }

        return Results.ok();

    }

    public String buildPath(String fileName) {

// TODO return the path where the file should be really stored

return null;

    }

FilenameUtils and FileUtils are Apache commons-io classes (by default available in ninja's dependencies I think).

I will work with disk and memory file provider. You "only" need to provide the final path where to store the file.

I hope it helps you,
