Nginx Mobile Theme

This plugin allows you to switch theme according to the User Agent on the Nginx reverse proxy.

Nginx Mobile Theme’s requirements are as follows.

• PHP 5.3 or later
• WordPress 3.7 or later
• Nginx Cache Controller 2.0.0 or later

Some Features

• You can flush mobile’s and pc’s each caches automatically via Nginx Cache Controller.
• Allow you to switch theme according to the user-agent.
• Allow you to customize multiple mobile device support via filter-hook.

Nginx Configuration

Add mobile device detection to the nginx.conf.

set $mobile '';
if ($http_user_agent ~* '(iPhone|iPod|incognito|webmate|Android|dream|CUPCAKE|froyo|BlackBerry|webOS|s8000|bada|IEMobile|Googlebot\-Mobile|AdsBot\-Google)') {
    set $mobile "@smartphone";
}

Set proxy_cache_key.

proxy_cache_key "$mobile$scheme://$host$request_uri";

Send custom request header to the backend.

proxy_set_header X-UA-Detect $mobile;

Nginx Mobile Theme will switch theme when ‘@smartphone’ is received in the $_SERVER['HTTP_X_UA_DETECT'].

How to use

1. Please access to the theme-customizer in the WordPress admin area.
2. Please select Mobile Theme in the drop-down.
3. Click “Save & Publish” button to save.

Multiple mobile device support

1. Add custom mobile detection to the nginx.conf.
2. Add custom mobile detection to the WordPress via nginxmobile_mobile_detects filter-hook.

nginx.conf:
set $mobile ”;
if ($http_user_agent ~* ‘(iPhone|iPod)’) {
set $mobile “@smartphone”;
}
if ($http_user_agent ~* ‘iPad’) {
set $mobile “@tablet”;
}

In your custom plugin:
add_filter(‘nginxmobile_mobile_detects’, function(){
return array(‘@smartphone’, ‘@tablet’);
});

• As a result, allow you to select theme for @smartphone and @tablet individually in the theme-customizer.
