Longtitude and Lattitude not calculated (0.000000) (Location, GMAP Location)

Posted by imehesz on December 29, 2009 at 4:43pm

hello everyone,

(although, I've created an issue ticket for this here http://drupal.org/node/670022, I'll ask you guys too)

I've seen some other (closed) tickets for this in the past (2008) but maybe it's a different issue. I created additional profile questions for my users (ie: firtsname and lastname) and enabled the location module (and the GMAP Location module).

I entered the GMAP API key,, so that should work just fine.

Here are my enabled modules:
GMAP, GMAP Location, Location, Location Search, User Locations, Profile

I also created the zipcode table (with a prefix!) and imported all the zip codes with the long and latt information.

So, when I create a user, it saves everything into the LOCATION table fine, but my lattitude and longtitude columns are always 0!

location_latlon_exact returns NULL

Posted by imehesz on December 29, 2009 at 10:12pm

so far I found out that this function:

location_latlon_exact returns NULL ...

function location_latlon_exact($location = array()) {
  $country = $location['country'];
  location_standardize_country_code($country);
  $service = variable_get('location_geocode_'. $country, 'none');
  if (!empty($country) && $service != 'none') {
    // figure out what the exact function should be
    if (strpos($service, '|')) {
      location_load_country($country);
      // The code change below fixes the problem of the country specific
      // function for geocoding not being correctly called (it removes any
      // text from the pipe (|) onwards)
      $exact_latlon_function = 'location_geocode_'. $country .'_'. substr($service, 0, strpos($service, '|'));
    }
    else {
      location_load_geocoder($service);
      $exact_latlon_function = $service .'_geocode_location';
    }
    if (function_exists($exact_latlon_function)) {
      return $exact_latlon_function($location);
    }
    else {
      return NULL;
    }
  }
  return NULL;
}

and here $service is always NULL, meaning that the variable location_geocode_us doesn't exists :/

hack

well, I kind of fixed the problem ...

I've created a hook function in my module for _user and during the validation process, I check if the user's long or lat is 0.... if so, I use the gmap_geocode() function to get the coordinates by the address and just simply change the $edit array with the real coordinates.

It wouldn't be efficient with a large project (or if you have multiple addresses for one person), but in my case it will do the trick...
