Dynamic Content w/ geolocation in WP?

I'm really just looking for ideas and guidance while foraging for memory processing in the WordPress CMS Divi Structure.

My company is in need of a good ContentPlaceholder solution. True to the MVC thinking we need to minimize the creation of redundant resources and yet create a national website that serves the regional concerns of different states. We are thinking of using geolocation (Google reverse lookup) but it has to allow standard users to add/manage the state dependant content blocks in WP.

CodeCanyon has a user role content placeholder plugin https://codecanyon.net/item/wordpress-content-placeholders/9259679

There is a service like https://geolify.com/

There is alot of discussion out there on using .htaccess URL rewriting or RewriteCondition. Perhaps something like URL.com/page?state_=TX

Maybe a custom PHP function could just pull the URL state value but I need to dig on PHP functionality within WP (with or without a custom plugin).

get_header();

get_footer();



 ?php $matches = Array();
 preg_match("/^\/questions/([0-9]+)\/([^\/]+)$/",
 $_SERVER['REQUEST_URI'], $matches);
 
 $db = new Database(); $seo_title = $db-getTitleById( $matches[1] );
 if( $seo_title != $matches[2] ) {   header( "Location:
 /questions/{$matches[1]}/{$seo_title}", TRUE, 301 );   exit(); } else
 {   display_the_page(); }

Another example:

RewriteEngine on RewriteCond %{ENV:GEOIP_COUNTRY_CODE} ^(US|CA)$ RewriteRule ^(.*)$ http://www.example.com/USA/$1 [L]
