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, IndependantBranches Insensitive.
GetBranchInfo() returns the same information without the problems of this function
(namespace collision, mainly).
Create a branch selector with the following code.
=head3 in PERL SCRIPT
my $branches = GetBranches;
my @branchloop;
foreach my $thisbranch (sort keys %$branches) {
my $selected = 1 if $thisbranch eq $branch;
my %row =(value => $thisbranch,
selected => $selected,
branchname => $branches->{$thisbranch}->{branchname},
);
push @branchloop, \%row;
}
=head3 in TEMPLATE
<select name="branch">
<option value="">Default</option>
<!-- TMPL_LOOP name="branchloop" -->
<option value="<!-- TMPL_VAR name="value" -->" <!-- TMPL_IF name="selected" -->selected<!-- /TMPL_IF -->><!-- TMPL_VAR name="branchname" --></option>
<!-- /TMPL_LOOP -->
</select>
=head4 Note that you often will want to just use GetBranchesLoop, for exactly the example above.
