Provides geographic information detected by an IP adress.

== 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](https://dev.maxmind.com/geoip/geoip2/web-services/#Languages-8)).

= Features: =

* You can use one of these data sources (see [comparison](https://github.com/yellowtree/geoip-detect/wiki/FAQ#which-data-source-should-i-choose)):
  * Free (default source): [HostIP.info](http://www.hostip.info/) (IPv4 only)
  * Free with registration: [Maxmind GeoIP2 Lite City](http://dev.maxmind.com/geoip/geoip2/geolite2/), automatically updated weekly
  * Commercial: [Maxmind GeoIP2 City](https://www.maxmind.com/en/geoip2-country-database) or [Maxmind GeoIP2 Country](https://www.maxmind.com/en/geoip2-city)
  * Commercial Web-API: [Maxmind GeoIP2 Precision](https://www.maxmind.com/en/geoip2-precision-services) (City, Country or Insights)
  * Hosting-Provider dependent: [Cloudflare](https://support.cloudflare.com/hc/en-us/articles/200168236-What-does-CloudFlare-IP-Geolocation-do-) or [Amazon AWS CloudFront](https://aws.amazon.com/blogs/aws/enhanced-cloudfront-customization/) (Country)
  * Free or Commercial Web-API: [Ipstack](https://ipstack.com)
  * Commercial Web-API via AWS Marketplace: [Fastah](https://aws.amazon.com/marketplace/pp/prodview-k5gjowexrefl2)
* Provides these 5 functions (see [API Documentation](https://github.com/yellowtree/geoip-detect/wiki/API:-PHP)):
  * `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)
* For the property names, see the results of a specific IP in the wordpress backend (under *Tools > Geolocation IP 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).
* You can show or hide content by using a shortcode `[geoip_detect2_show_if country="FR, DE" not_city="Berlin"]TEXT[/geoip_detect2_show_if]`. See [Shortcode Documentation](https://github.com/yellowtree/geoip-detect/wiki/API:-Shortcodes#show-or-hide-content-depending-on-the-location).
* When enabled on the options page, it adds CSS classes to the body tag such as `geoip-province-HE`, `geoip-country-DE` and `geoip-continent-EU`.
* If you are using a page cache, it is recommended to use the AJAX mode (see [AJAX](https://github.com/yellowtree/geoip-detect/wiki/API:-AJAX))
* When enabled on the options page, the client IP respects a reverse proxy of the server.
* If you are using [Contact Form 7](https://wordpress.org/plugins/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]`
  * A text input that is pre-filled with the detected city (or other property): `[geoip_detect2_text_input city property:city lang:fr id:id class:class default:Paris]`
  * Geolocation information for the email text: `[geoip_detect2_user_info]`
* If you are using [WP Forms](https://wordpress.org/plugins/wpforms-lite/), you can use this shortcode:
  * Geolocation information for the email text: `[geoip_detect2_user_info]`
* Together with [SVG Flags](https://wordpress.org/plugins/svg-flags-lite/) you can show the flag of the detected country: `[geoip_detect2_current_flag]` (see [documentation](https://github.com/yellowtree/geoip-detect/wiki/API:-Shortcodes#add-a-flag-of-the-visitors-country))

See [Documentation](https://github.com/yellowtree/geoip-detect/wiki) for more info.

= How can I use these functions? =

* You could choose the currency of the store based on the country name
* You could pre-fill the shipping country
* 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!
* Be careful to comply to the applicable laws. For example Regulation (EU) 2018/302 ...
* If you need to get the user's timezone, it is more accurate to use JS solutions.

**System Requirements**: You will need at least PHP 7.2.5 . Also, if you use the plugin WooCommerce, you'll need at least WooCommerce 3.9.0 .

*[Here are other ways to contribute to the development of this plugin.](https://github.com/yellowtree/geoip-detect/blob/master/CONTRIBUTING.md)*

*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](https://www.whatismyip.com/)?
* Or maybe you are using a site cache plugin. Then enable the option `Disable caching a page that contains a shortcode or API call to geo-dependent functions.`

* Library updates

= 5.0.0 =
In this release, there a small breaking changes marked by [!].

AJAX mode:
* FIX [!]: Empty attribute values such as `[geoip_detect2_show_if country=""]Country was not detected[/geoip_detect2_show_if]` are now working (they were ignored before)
* FIX [!]: Shortcodes that have an invalid value for the property `ajax` (e.g. `[geoip_detect2_text_input ajax="invalid"]`) are now using the AJAX option instead of always disabling AJAX
* FIX: In CF7, the country selector can now be used in AJAX mode
* FIX: In AJAX mode, the shortcode `[geoip_detect2_show_if]` renders as a `<div>` if it detects that the containing content has HTML block level elements
* NEW (Beta): In AJAX mode, the new property `autosave` saves the user input as local override for this browser. `[geoip_detect2_countries mycountry autosave]` and `[geoip_detect2_text_input city property:city autosave]`. (Please give feedback if this works as expected!)
* FIX: In AJAX mode, calling the method `set_override(record, duration_in_days)` now refreshes the AJAX shortcodes and CSS body classes.
-> Thus, it is now possible to quickly implement different content for different countries with an autodetected default country, see https://github.com/yellowtree/geoip-detect/wiki/API-Usage-Examples#country-selector-that-can-be-overridden-by-the-user

Other changes:
* NEW: Drastically improving performance if the lookup is performed for the current IP more than once (e.g. because of shortcodes without AJAX mode)
* UI: Showing the time for the subsequent lookup on the Test Lookup page
* FIX: Maxmind Datasource: Check if the database file is really a file, not a directory
* NEW: Header Datasource: Now a custom HTTP header can be used via the wordpress filter `geoip_detect2_source_header_http_key`

Other minor changes:
* Update the list of available APIs for getting the external IP (as whatismyip went down)
* Minimum Wordpress version is 5.4 now. 
* Update some internal libraries & dev tools
* Checked compatibility with PHP 8.1

The code of the plugin has not changed much, I have named this version 3.0 to indicate the major change on Maxmind's side of things. They explain it in this blog post:
