C4::Branch - Koha branch module
|
|
|
|
=head1 SYNOPSIS
|
|
|
|
use C4::Branch;
|
|
|
|
=head1 DESCRIPTION
|
|
|
|
The functions in this module deal with branches.
|
|
|
|
=head1 FUNCTIONS
|
|
|
|
=head2 GetBranches
|
|
|
|
$branches = &GetBranches();
|
|
returns informations about ALL branches.
|
|
Create a branch selector with the following code
|
|
IndependantBranches Insensitive...
|
|
GetBranchInfo() returns the same information without the problems of this function
|
|
(namespace collision, mainly). You should probably use that, and replace GetBranches()
|
|
with GetBranchInfo() where you see it in the code.
