Hi,

Someone got the solution ? The problem is very important for me. I can't manage to add fields when we upload a file.

Thanks
Alexandre

Alfonso found the solution :

in the atClick method:

                          var file=element.getInputElement();
                                    var form = file.getParent().$;
                                    /* form is now a normal <form> element inside an iframe*/
                                    var doc = form.ownerDocument;
                                    var data1 = doc.createElement('input')
                                    data1.type='hidden';
                                    data1.name='data1';
                                    data1.value='myvalue';
                                    form.appendChild(data1);
                                    var keywords = doc.createElement('input')
                                    keywords.type='hidden';
                                    keywords.name='keywords';
                                    keywords.value=dialog.getContentElement( 'Upload', 'keywords' ).getValue();
                                    form.appendChild(keywords);

                                    // etc...
