GeoIP Tokens

Standalone module that provides tokens with geolocation information based on IP addresses.

  • Country code [geoip_tokens:country_code]
  • Latitude [geoip_tokens:latitude]
  • Longitude [geoip_tokens:longitude]
  • Timezone name [geoip_tokens:timezone]

The information is retrieved from external services, the IP addresses get anonymized to comply with GDPR.

To make use of this module, your Backdrop site must be able to do external requests - which is usually the case.

The services (see credits section below) get randomly queried, the results for the anonymized IPs get cached in a local database for a while, to avoid too many requests.

Use cases

Typical use-cases are sites that provide services that need some infos about the visitor's or user's geographical position.

For example, to center a map, to redirect to specific pages or forms for different countries, to display messages with country specific info, or to display dates in the proper timezone.

Rules support

Additionally to the tokens, this module also ships with Rules support. Two conditions are available:

  • Compare the current IP with a configurable list of countries
  • Check if current IP is within the European Union

Precision of results

The results are not as exact as, for instance, GPS. Geolocation based on IP addresses can only be approximate. The results may even be wrong for a while, until a service provider updates outdated information. So don't blindly rely on the results.

When not to use this module

This module has been written with low- to medium-traffic sites in mind. If your site has really high traffic on pages that use the tokens, you might easily burst the (generous) limits of the providers in use. Although this module tries to distribute the load and to cache locally. "High traffic" means: thousands of requests per day.

For developers

While tokens can be helpful, you might need something more specific, like juggling with GeoIP data via hook_form_alter().

In this case use the function geoip_tokens_get_geoip_info() directly. Its optional parameter can be one of:

  • all (the default)
  • latlon
  • country_code
  • timezone

You get a keyed array of values.

If you need to get things working with cached pages and anonymous users, use the Ajax API. See the example in js/geoip_tokens.js, note that the ajax parameters are slightly different.

Backdrop.geoipTokens.getData('ccode').done(function (data) {
  // Your callback here.
  // "data" contains the values you requested.
});

Installation

No library or binary database file required. This module is really standalone.
