From 500afcb706608612e09f71da726c21c6f65a63a4 Mon Sep 17 00:00:00 2001 From: Julian Maurice Date: Wed, 18 Jul 2012 16:47:54 +0200 Subject: [PATCH] Bug 6874: File upload in MARC New cataloging plugin upload.pl and new system preference 'uploadPath'. upload.pl provide a way to upload files on the server and store a link (url) to it in MARC uploadPath is the absolute path on the server where the files will be stored. It's possible to have a hierarchy of directories under this path and the plugin will allow to choose in which directory to store the file. Stored value in MARC subfield looks like this: /cgi-bin/koha/opac-retrieve-file.pl?id= So both 'uploadPath' and 'OPACBaseURL' sysprefs have to be set for this plugin to work correctly Signed-off-by: Kyle M Hall Signed-off-by: Paul Poulain Signed-off-by: Jared Camins-Esakov --- C4/Biblio.pm | 29 ++- C4/UploadedFiles.pm | 226 ++++++++++++++++++++ basket/basket.pl | 2 +- catalogue/MARCdetail.pl | 1 - catalogue/detail.pl | 2 +- cataloguing/value_builder/upload.pl | 178 +++++++++++++++ installer/data/mysql/kohastructure.sql | 10 + installer/data/mysql/sysprefs.sql | 1 + installer/data/mysql/updatedatabase.pl | 21 ++ .../en/modules/admin/preferences/cataloguing.pref | 4 + .../en/modules/cataloguing/value_builder/upload.tt | 71 ++++++ .../value_builder/upload_delete_file.tt | 60 ++++++ opac/opac-basket.pl | 2 +- opac/opac-detail.pl | 2 +- opac/opac-retrieve-file.pl | 47 ++++ 15 files changed, 645 insertions(+), 11 deletions(-) create mode 100644 C4/UploadedFiles.pm create mode 100755 cataloguing/value_builder/upload.pl create mode 100644 koha-tmpl/intranet-tmpl/prog/en/modules/cataloguing/value_builder/upload.tt create mode 100644 koha-tmpl/intranet-tmpl/prog/en/modules/cataloguing/value_builder/upload_delete_file.tt create mode 100755 opac/opac-retrieve-file.pl diff --git a/C4/Biblio.pm b/C4/Biblio.pm index cf83ae6..4997d89 100644 --- a/C4/Biblio.pm +++ b/C4/Biblio.pm @@ -37,6 +37,7 @@ use C4::ClassSource; use C4::Charset; use C4::Linker; use C4::OAI::Sets; +use C4::UploadedFiles; use vars qw($VERSION @ISA @EXPORT); @@ -1907,7 +1908,7 @@ sub GetMarcAuthors { =head2 GetMarcUrls - $marcurls = GetMarcUrls($record,$marcflavour); + $marcurls = GetMarcUrls($record,$marcflavour,$frameworkcode); Returns arrayref of URLs from MARC data, suitable to pass to tmpl loop.
