Usage

= GeoSwitch Conditional Blocks =

GeoSwitch uses two shortcodes [geoswitch] and [geoswitch_case] to create conditional blocks.
The [geoswitch] shortcode is used to enclose one or more [geoswitch_case] shortcodes with different conditions. The
[geoswitch_case] shortcodes enclose content that will be shown if the condition is true.
The following example illustrates a GeoSwitch conditional block that will show different contact information depending
on the user’s IP location:

[geoswitch]
[geoswitch_case country_code="AU" state_code="NSW"]New South Wales Office[/geoswitch_case]
[geoswitch_case country_code="AU"]Australian Office[/geoswitch_case]
[geoswitch_case]International Office[/geoswitch_case]
[/geoswitch]

The above GeoSwitch block will display “New South Wales Office” to users in New South Wales within Australia,
“Australian Office” to other Australian users and “International Office” to any other user.

The [geoswitch_case] shortcode accepts the following attributes:

• country – comma delimited list of country names
• country_code – comma delimited list of country ISO codes
• state – comma delimited list of of state names
• state_code – comma delimited list of state ISO codes
• city – comma delimited list of city names
• within, from – This set of attributes is used to test for distances. Within is the distance in kilometers or miles and
  from is the centre point represented as “latitude,longitude” in degrees (example [geoswitch within=”10” from=”-33.7167,151.6”]).

The [geoswitch_case] shortcode matches only the attributes specified so:

[geoswitch]
[geoswitch_case city="paris"]You are in Paris![/geoswitch_case]
[/geoswitch]

Will display “You are in Paris!” to any user with an IP location in a city named Paris, e.g Paris, France or Paris, Texas, USA.
A [geoswitch_case] shortcode without any attributes always matches and can be used as the last condition in a conditional block
to show default content.
Content between [geoswitch_case] blocks can contain any markup including any other shortcodes, but conditional blocks should
not be nested as this is not supported by WordPress.
Content between the [geoswitch] and [geoswitch_case] shortcodes should be whitespace but is usually ignored:

[geoswitch] *DON’T WRITE HERE*
[geoswitch_case]...[/geoswitch_case] *OR HERE*
[geoswitch_case]...[/geoswitch_case]
[/geoswitch]

Informational Shortcodes

In addition to the conditional block GeoSwitch offers the following shortcodes to display user information:

• [geoswitch_ip] – The user’s IP.
• [geoswitch_city] – The user’s city name.
• [geoswitch_state] – The user’s state name.
• [geoswitch_state_code] – The user’s state ISO code.
• [geoswitch_country] – The user’s country name.
• [geoswitch_country_code] – The user’s country code.

If the IP of the user cannot be geo located these shortcodes return ‘?’

Debug Shortcodes

• geoswitch_setip – Override the user IP. Affects shortcodes after this one.
  Usage:

  [geoswitch_case ip=’10.0.0.10′]

For debugging whole websites the user IP can be set globally in the admin settings for the plugin.

Filter Hooks

Geoswitch supports the following filter hooks:
geoswitch_skip_ip_check
Allows to programatically skip the ip check. If the hook callback function returns true the MaxMind libraries are not used to check the IP and the
default content (if configured) will be displayed.
Usage:

function skip_ip_callback( $skipCheck, $userIp ) {
    if ( some_custom_test($userIp) ) {
        $skipCheck = true;
    }
    return $skipChek;
}

add_filter( 'geoswitch_skip_ip_check', 'skip_ip_callback', 10, 2 );
