too have I the Upload-management correct, so one now only yet on "Datei hinzufügen" (ruddy) clicking and a File select must and the Upload then automatically happens:
so too with the Update file Button (blue).
so is it eindeutiger whether is a new file Upload- or a already hochgeladene Update file would like.
my ploy: not always and not all Browsern inputted File-Input in its .value-Attribut a worth back. the has now changed. so can I look, whether the File-Input.value a Filenames contain and the form self put down. too can the File-Input now The quality display.none own and it functions nevertheless. so against can I a own Button Show (File-add) and by .click-method the File-Input whom LoadFile-dialog open. thereafter becomes only yet geschaut whether the File-Input a .value own and if so, then becomes the form abgesendet. so funktionierts too with the File-update-Button.
the whole Although right tricky and need bisl JS, but it functions very reliably and bid explicit More comfort. whom ploy I had me for InfinityProfan-IDE ausgedacht and there functions it likewise.
