+
+SL::Controller::File - Controller for managing files
+
+=head1 SYNOPSIS
+
+The Controller is called directly from the webpages
+
+ <a href="controller.pl?action=File/list&file_type=document\
+ &object_type=[% HTML.escape(type) %]&object_id=[% HTML.url(id) %]">
+
+
+or indirectly via javascript functions from js/kivi.File.js
+
+ kivi.popup_dialog({ url: 'controller.pl',
+ data: { action : 'File/ajax_upload',
+ file_type : 'uploaded',
+ object_type: type,
+ object_id : id
+ }
+ ...
+
+=head1 DESCRIPTION
+
+This is a controller for handling files in a storage independent way.
+The storage may be a Filesystem,a WebDAV, a Database or DMS.
+These backends must be configered in ClientConfig.
+This Controller use as intermediate layer for storage C<SL::File>.
+
+The Controller is responsible to display forms for displaying the files at the ERP-objects and
+for uploading and downloading the files.
+
+More description of the intermediate layer see L<SL::File>.
+

+
+=item C<form.file_type>
+
+For one ERP-object may exists different type of documents the type may be "documents","attachments" or "images".
+This file_type is a filter for the list.
