[Plugin: Cimy User Extra Fields] Asign $_POST['from'] to a cimy fields

Is there any way of assigning a $_POST value to a cimy field? I have been trying to do this all day but haven’t suceeded, the only way that worked in a partyal way was to have a loop after the form which waits for an input but that also stops the rest of the page to be loaded so it’s out of discussion.
