how do I run ci4 app inside a subfolder of wordpress

use this

Code:

RewriteEngine On
  RewriteCond %{HTTPS} !=on
  RewriteCond %{THE_REQUEST} /wordpres/folder/([^\s?]*) [NC]
  RewriteRule ^ %1 [L,NE,R=302]
  RewriteRule ^((?!wordpres/folder/).*)$ wordpres/folder/$1 [L,NC]

is it for CI or WordPress?

This is for the folder where you want to point so this .htaccess help you find your folder where you want to..eg wordpress/folder/

because I don't know how you figure out your app basically you put in a root in WordPress to point your subfolder

so wrdpress/folder/ these are two directors it is you to decide either WordPress or plus folder =wordpress/folder/ change as you wish so just modify to use from WordPress to yours folder

for example here you can hide a public folder in CI4 by using this in a CI root

Code:

RewriteEngine On
  RewriteCond %{HTTPS} !=on
  RewriteCond %{THE_REQUEST} /public/([^\s?]*) [NC]
  RewriteRule ^ %1 [L,NE,R=302]
  RewriteRule ^((?!public/).*)$ public/$1 [L,NC]
