The obvious problem is that you are trusting user input (http headers) which makes your code suspicious from security POV. Other then that, no real problems with it, but my experience is that such hacks have a tendency to just move whatever problem you are trying to solve this way to another place.
There is actually nothing unique about setting multisite on XAMPP, all you need to do is properly configure the webserver as a proper webserver, and skip the lazy practice of using localhost as your site domain. Select some random domain you are not likely to use in your web use, edit your hosts file to … Read more
Make sure you’ve set up your rewrite rules in your .htaccess file. The Multisite rules are different from the default WordPress rules. If this is an up-to-date version of WordPress, your .htaccess rewrite rules should look like this: Subdirectory RewriteEngine On RewriteBase / RewriteRule ^index\.php$ – [L] # add a trailing slash to /wp-admin RewriteRule … Read more
