=head1 NAME
|
|
|
|
labels/label-create-pdf.pl - A script for creating a pdf export of labels and label batches in Koha
|
|
|
|
=head1 ABSTRACT
|
|
|
|
This script provides the means of producing a pdf of labels for items either individually, in groups, or in batches from within Koha.
|
|
|
|
=head1 USAGE
|
|
|
|
This script is intended to be called as a cgi script although it could be easily modified to accept command line parameters. The script accepts four single
|
|
parameters and two "multiple" parameters as follows:
|
|
|
|
C<batch_id> A single valid batch id to export.
|
|
C<template_id> A single valid template id to be applied to the current export. This parameter is manditory.
|
|
C<layout_id> A single valid layout id to be applied to the current export. This parameter is manditory.
|
|
C<start_label> The number of the label on which to begin the export. This parameter is optional.
|
|
C<lable_ids> A single valid label id to export. Multiple label ids may be submitted to export multiple labels.
|
|
C<item_numbers> A single valid item number to export. Multiple item numbers may be submitted to export multiple items.
|
|
|
|
B<NOTE:> One of the C<batch_id>, C<label_ids>, or C<item_number> parameters is manditory. However, do not pass a combination of them or bad things might result.
|
|
|
|
example:
|
|
http://staff-client.kohadev.org/cgi-bin/koha/labels/label-create-pdf.pl?batch_id=1&template_id=1&layout_id=5&start_label=1
