---++ StaticMethod upload( $session )
=upload= command handler.
This method is designed to be
invoked via the =TWiki::UI::run= method.
CGI parameters, passed in $query:
| =hidefile= | if efined, will not show file in attachment table |
| =filepath= | |
| =filename= | |
| =filecomment= | Comment to associate with file in attachment table |
| =createlink= | if defined, will create a link to file at end of topic |
| =changeproperties= | |
Does the work of uploading a file to a topic. Designed to be useable as
a REST method (it will redirect to the 'view' script unless the 'noredirect'
parameter is specified, in which case it will print a message to
STDOUT, starting with 'OK' on success and 'ERROR' on failure.
