Retrieving Geo-Information using one the Maxmind GeoIP2 databases.

Description

Provides geographic information detected by an IP adress. This can be used in themes or other plugins, as a shortcode, or via CSS body classes. The city & country names are translated in different languages (supported languages).

= Features: =

Provides these 5 functions (see API Documentation):
- geoip_detect2_get_info_from_ip($ip, $locales = array('en'), $options = array()): Lookup Geo-Information of the specified IP
- geoip_detect2_get_info_from_current_ip($locales = array('en'), $options = array()): Lookup Geo-Information of the current website user
- geoip_detect2_get_current_source_description(...): Return a human-readable label of the currently chosen source.
- geoip_detect2_get_external_ip_adress(): Fetch the internet adress of the webserver
- geoip_detect2_get_client_ip(): Get client IP (even if it is behind a reverse proxy)
You can use one of these data sources (see comparison):
- Free: Maxmind GeoIP2 Lite City, automatically updated every month (licensed CC BY-SA. See FAQ.)
- Commercial: Maxmind GeoIP2 City or Maxmind GeoIP2 Country
- Commercial Web-API: Maxmind GeoIP2 Precision (City, Country or Insights)
- Free (default source): HostIP.info (IPv4 only)
- Hosting-Provider dependent: Cloudflare or Amazon AWS CloudFront (Country)
For the property names, see the results of a specific IP in the wordpress backend (under Tools > GeoIP Detection).
You can include these properties into your posts and pages by using the shortcode [geoip_detect2 property="country.name" default="(country could not be detected)" lang="en"] (where 'country.name' can be one of the other property names as well, and 'default' and 'lang' are optional).
When enabled on the options page, it adds CSS classes to the body tag such as geoip-country-DE and geoip-continent-EU.
When enabled on the options page, the client IP respects a reverse proxy of the server.
If you are using Contact Form 7, you can use these shortcodes:
- A select input with all countries, the detected country being selected by default [geoip_detect2_countries mycountry]
- Tracking information for the email text [geoip_detect2_user_info]

See API Documentation for more info.

= How can I use these functions? =

You could choose the currency of the store based on the country name
You could suggest an timezone to use when displaying dates
You could show the store nearest to your customer
You show or hide content specific to a geographic target group
Etc. ... You tell me! I'm rather curious what you'll do with this plugin!

System Requirements: You will need at least PHP 5.4.

This extension is "charity-ware". If you are happy with it, please leave a tip for the benefit of this charity. (See FAQ for more infos.)

This product can provide GeoLite2 data created by MaxMind, available from http://www.maxmind.com.

Installation

Install the plugin
Go to the plugin's option page and choose a data source.
Test it by clicking on "Lookup" on the lookup page.

Troubleshooting

Does geoip_detect2_get_info_from_current_ip() return the same country, regardless of where you are visiting the site from? Maybe your server has a reverse proxy configured. You can check this: Go to the options page and look for "reverse proxy". Are there 2 IPs listed there? If so, which one corresponds to your public IP?
