function ip_geoloc_init in IP Geolocation Views & Maps 7

Implements hook_init().

Due to the weight set in ip_geoloc.install this hook is called after all other hook_init() implementations have completed. hook_inits are called as the last step in _drupal_bootstrap_full(), file includes/common.inc Note that the {accesslog} is updated in statistics_exit(), i.e. after the page is loaded. This means that a second click may be required before the current position marker appears on the recent visitor map.

    // optionally (default) use Google Maps API to reverse-geocode the lat/lon
    // into a street address.
    // This is all done via client-side calls, so the Drupal server will not
    // rake up any calls against its Google-imposed quotum, i.e. the
    // OVER_QUERY_LIMIT.
    // When done, the javascript calls us back on the default menu callback,
    // '/js/ip_geoloc/current_location', which receives the geolocation data
    // from the Google Maps call via the $_POST variable and stores it on the
    // session.
    // Naturally all of this will only work if the browser is connected to
    // the internet and has javascript enabled.
