Display map only when there's information to show

You should be able to get this to work by passing arguments into the map.

<?php
$args = array
(
    'map_content' => 'single',
    'load_empty_map' => false,
);
echo GeoMashup::map($args);
?>

If you wanted to still use an if statement, something like this may work:

<?php if (GeoMashup::info()):?>
    <div id="geomashup">
        <?php echo GeoMashup::map() ?>
    </div>
<?php endif;?>

Although, as far as I can tell from the Wiki it looks like your supposed to use “GeoMashup::location_info()”

Here’s snippet you can use:
