When the user dismisses the output of phase2, they are returned to +an "appropriate" directory listing in general. + + This is part of the LearningOnline Network with CAPA project +described at http://www.lon-capa.org. + +=head2 Subroutines + +=cut package Apache::loncfile; use strict; use Apache::File; +use File::Basename; use File::Copy; +use HTML::Entities(); use Apache::Constants qw(:common :http :methods); -use Apache::loncacc; +use Apache::lonnet; +use Apache::loncommon(); +use Apache::lonhtmlcommon; +use Apache::lonlocal; +use LONCAPA qw(:DEFAULT :match); -sub phaseone { - my ($r,$fn,$uname,$udom)=@_; +my $DEBUG=0; +my $r; # Needs to be global for some stuff RF. - $fn=~/(.*)\/([^\/]+)\.(\w+)$/; - my $dir=$1; - my $main=$2; - my $suffix=$3; - - my $conspace='/home/'.$uname.'/public_html'.$fn; - - $r->print('
