File Upload with Lift - Scala

As I continue to use Lift, I decided to add a file upload to one of my side projects. I had seen the SHtml.fileUpload method before, so I thought it was going to be one of those 5 minutes things.

A few days later and several email exchanges with Jeppe on the mailing list, I finally got it to work. Not that it was hard, but there was a tiny detail that was staring at me the whole time, but I just could not see it.

The culprit.

My template

I had

<form class="lift:Upload?form=post” multipart=”true">

and Jeppe was kind enough to point out that I should instead use:

<form class="lift:Upload?form=post;multipart=true">

You can think of multipart=true is one more parameter that is sent to lift:Upload

I hope that this would save you some time, and if not, at least it reinforces the importance of asking on the mailing list and providing a sample application to reproduce your problem.

Sample application.

I put together a sample application that uses the CSS Selector Transformation (also known as designer friendly template) and it is hosted on github.com

Note that the images are stored on the webapp folder, this should be changed before you go in production :)

Enjoy
