BTW, the same seems to apply to the setDefaults too. You can read in the documentation that: "It is perfectly legal to do call Page's setDefaults() from within buildForm()..." (see http://pear.php.net/manual/en/package.html.html-quickform-controller.intro.php) Shouldn't this also be reflected in the $_SESSION variable independed from where you setDefaults() from? > As you want to change the value of an element (your textarea) with the > content of another element (your uploaded file), I suggest acting directly > on the container values ($controller->container()), which > references element > values such as stored in the session. > > 1.

I suppose point 4 means I should update the textarea value according to (in my action class): $data =& $page->controller->container(); $data['values']['textarea_name'] .= $text_file_contents; Do I need the ['uploads'] index anyway? If I use it I must unset it so the file content dosen't append everytime I reload the pages after having done the file upload. > > I will make an example for that and other stuff like uploading images and > changing the content of a page based on the content of another page this > week.
