KDK Domain URL Normalizer (v1.1.0 / Jan 2020)
A simple plugin to rewrite multiple domains or subdomains to a single domain in the site's HTML output.
The plugin can also normalize the domain protocol (http:// to https:// and vice versa) as well as additional ports (e.g. example.com:8080 to www.example.com and vice versa).
Some practical uses:
- Normalize the domain after migrating WordPress from a test domain to the production one.
- Allow the WordPress admin to be served from a different subdomain (e.g. when WordPress is served over a CDN and you want to avoid any caching of static data etc.). This would require passing on multiple domains/subdomains in your wp-config.php file like so:
// Map multiple domains in WordPress
define('KDK_WP_PRIMARY_DOMAIN', 'www.domain.tld');
define('KDK_WP_SECONDARY_DOMAINS', serialize(array(
'www2.domain.tld',
'admin.domain.tld',
'whatever.domain.tld'
)));
define('KDK_WP_DOMAIN_PROTOCOL', 'https');
if (in_array($_SERVER['HTTP_HOST'], unserialize(KDK_WP_SECONDARY_DOMAINS))) {
define('WP_HOME', KDK_WP_DOMAIN_PROTOCOL.'://'.$_SERVER['HTTP_HOST']);
define('WP_SITEURL', KDK_WP_DOMAIN_PROTOCOL.'://'.$_SERVER['HTTP_HOST']);
} else {
define('WP_HOME', KDK_WP_DOMAIN_PROTOCOL.'://'.KDK_WP_PRIMARY_DOMAIN);
define('WP_SITEURL', KDK_WP_DOMAIN_PROTOCOL.'://'.KDK_WP_PRIMARY_DOMAIN);
}
// Share cookies across subdomains
define('COOKIE_DOMAIN', '.domain.tld');
- When you want to switch your site from HTTP to HTTPS and you want all internal resources to be properly linked through HTTPS as well.
To Do
- Add option to control caching (home/inner pages)
- Add option for executing in the backend
- Add new *.ini based language file
