I have already known how to do that. I have another question: I have a form with 3 file inputs and an "Attach" button. After click this button, 3 files are attached to the current document. How can I do this using the XWiki action /xwiki/bin/upload ?. I tried but only 1 file is allowed. ------------------------------------------------------------------------ _______________________________________________ users mailing list users(a)xwiki.org http://lists.xwiki.org/mailman/listinfo/users

My solution sounds silly but it works :) Assume that the upload document is named XWiki.Upload. In this document, I change the value of the hidden field "xredirect" to XWiki.DoSomething. I create another document named XWiki.DoSomething, in it, write some code to deal with the file content, blah ... , finally, redirect back to XWiki.Upload.
