=head1 INTRODUCTION |
|
|
|
This module uploads a file sitting on a client computer into |
|
library server construction space. |
|
|
|
This is part of the LearningOnline Network with CAPA project |
|
described at http://www.lon-capa.org. |
|
|
|
=head1 HANDLER SUBROUTINE |
|
|
|
This routine is called by Apache and mod_perl. |
|
|
|
=over 4 |
|
|
|
=item * |
|
|
|
Initialize variables |
|
|
|
=item * |
|
|
|
Start page output |
|
|
|
=item * |
|
|
|
output relevant interface phase (phaseone, phasetwo, phasethree or phasefour) |
|
|
|
=item * |
|
|
|
(phase one is to specify upload file; phase two is to handle conditions |
|
subsequent to specification--like overwriting an existing file; phase three |
|
is to handle processing of secondary uploads - of embedded objects in an |
|
html file). |

=back |
|
|
|
=head1 OTHER SUBROUTINES |
|
|
|
=over |
|
|
|
=item phaseone() |
|
|
|
Interface for specifying file to upload. |
|
|
|
=item phasetwo() |
|
|
|
Interface for handling post-conditions about uploading (such |
|
as overwriting an existing file). |
|
|
|
=item phasethree() |
|
|
|
Interface for handling secondary uploads of embedded objects |
|
in an html file. |
|
|
|
=item phasefour() |
|
|
|
Interface for handling optional renaming of links to embedded |
|
objects. |
|
|
|
=item upfile_store() |
|
|
|
Store contents of uploaded file into temporary space. Invoked |
|
by phaseone subroutine. |
|
|
|
=item check_extension() |
|
|
|
Checks if filename extension is permitted and checks type |
|
of file - if html file, calls parser to check for embedded objects. |
|
Invoked by phasetwo subroutine. |
