Upload file in front-end

[matjazp]

I have a page with files (attachments). I would like to allow a user to add files as simple as possible. I don't want to give the user full access to admin. So click on the link/button "Add new attachment" would open modal with login form, after successful login a file upload would be presented to the user and he would upload the file. Thanks for any hints.

I think there are already lots of thready / posts that covers that: just google

horst, thx for the hints. Another question: how to "move" individual file object from one File field to another File field without removing the file itself? Eg. have a page with two fields: files (multiple files are allowed) and onefile (maximum file upload = 1). User is allowed to access just onefile (I'm using fredi), he uploads the file and then this new uploaded file should get appended to other files:

if($page->onefile && count($page->onefile)) {
	$page->setOutputFormatting(false);
	$page->files->append($page->onefile);
	$page->save();
	$page->setOutputFormatting(true);
}

 Now I would like to "empty" onefile field (to be ready for the nex upload) but without deleting the actual file itself.
