=head2 store_data
|
|
|
|
store_data allows a plugin to store key value pairs in the database for future use.
|
|
|
|
usage: $self->store_data({ param1 => 'param1val', param2 => 'param2value' })
|

|
|
}
|
|
}
|
|
|
|
=head2 retrieve_data
|
|
|
|
retrieve_data allows a plugin to read the values that were previously saved with store_data
|
|
|
|
usage: my $value = $self->retrieve_data( $key );
|
|
|
|
=cut
|

=head2 get_template
|
|
|
|
get_template returns a Template object. Eventually this will probably be calling
|
|
C4:Template, but at the moment, it does not.
|
|
|
|
=cut

=head2 get_qualified_table_name
|
|
|
|
To avoid naming conflict, each plugins tables should use a fully qualified namespace.
|
|
To avoid hardcoding and make plugins more flexible, this method will return the proper
|
|
fully qualified table name.
|
|
|
|
usage: my $table = $self->get_qualified_table_name( 'myTable' );
|
|
|
|
=cut
|

|
|
sub get_qualified_table_name {
|

|
|
}
|
|
|
|
=head2 get_plugin_http_path
|
|
|
|
To access a plugin's own resources ( images, js files, css files, etc... )
|
|
a plugin will need to know what path to use in the template files. This
|
|
method returns that path.
|
|
|
|
usage: my $path = $self->get_plugin_http_path();
|
|
|
|
=cut
|
|
|
|
sub get_plugin_http_path {
|
|
my ($self) = @_;

return "/plugin/" . join( '/', split( '::', $self->{'class'} ) );
|
|
}
|
|
|
|
=head2 go_home
|
|
|
|
go_home is a quick redirect to the Koha plugins home page
|

=cut

sub go_home {
|
|
my ( $self, $params ) = @_;
