=head1 NAME
FixMyStreet::App::Controller::Location - Catalyst Controller
=head1 DESCRIPTION
Catalyst Controller.
This is purely an internal controller for keeping all the location finding things in one place
=head1 METHODS
=head2 determine_location_from_coords
Use latitude and longitude if provided in parameters.
=cut
sub determine_location_from_coords : Private {
my ( $self, $c ) = @_;
my $latitude = $c->req->param('latitude') || $c->req->param('lat');
my $longitude = $c->req->param('longitude') || $c->req->param('lon');
if ( defined $latitude && defined $longitude ) {
$c->stash->{latitude} = $latitude;
$c->stash->{longitude} = $longitude;
# Also save the pc if there is one
if ( my $pc = $c->req->param('pc') ) {
$c->stash->{pc} = $pc;
}
return $c->forward( 'check_location' );
}
return;
}
=head2 determine_location_from_pc
User has searched for a location - try to find it for them.
If one match is found returns true and lat/lng is set.
If several possible matches are found puts an array onto stash so that user can be prompted to pick one and returns false.
If no matches are found returns false.
=cut

# If we got a lat/lng set to stash and return true
if ( defined $latitude && defined $longitude ) {

=head2 check_location
Just make sure that for UK installs, our co-ordinates are indeed in the UK.
