You can filter domain_exists, a check that runs before a site is registered. If you return a positive integer, WordPress will not create that site. Despite its name, that filter lets you check the path too. Sample code, not tested: add_filter( ‘domain_exists’, function( $result, $domain, $path ) { // Already taken, no need for further … Read more
The difference in your case is in filters being applied to output of these functions. While bloginfo applies one of these filters: if ( ‘display’ == $filter ) { if ( $url ) $output = apply_filters(‘bloginfo_url’, $output, $show); else $output = apply_filters(‘bloginfo’, $output, $show); } Function home_url applies this filter: return apply_filters( ‘home_url’, $url, $path, … Read more
There’s a pretty good step by step on moving WordPress in the Codex. It is what I follow when changing domains. Moving the files is pretty straight-forward. It is the hard-coded references in the database that are tricky. However, serialized search and replace will take care of all database changes. I’ve used the Velvet Blues … Read more
Use the field in the admin Settings > Permalinks page to set your permalink structure to /blog/%year%/%monthnum%/%postname%/. To prevent custom post types from inheriting the post permalink structure, set with_front to false in your register_post_type arguments for all custom post types. Version 4.4 also added the register_post_type_args filter to allow modification of post type arguments … Read more
I usually just avoid the issue entirely every time I create a new wordpress site: define(‘WP_HOME’, “https://wordpress.stackexchange.com/”); define(‘WP_SITEURL’, “https://wordpress.stackexchange.com/”); will cause wordpress to use root-relative urls for everything. Makes site migrations to other domains far easier. Ofc, if you access your site using a folder (eg. “http://<domain>/blog“) you could change them to: define(‘WP_HOME’, ‘/blog/’); define(‘WP_SITEURL’, … Read more
There are 5 values need to change. From database. wp_options: options named “siteurl” and “home” wp_site wp_sitemeta: the option named “siteurl” wp_blogs: any entries in the “domains” column that have the old domain name wp_#_options: Each sub-site will have sets of tables that correspond to the blog_id in the wp_blogs table. You need to go … Read more
You can get the value of front in the global $wp_rewrite: global $wp_rewrite; echo $wp_rewrite->front; // or echo home_url( $wp_rewrite->front ); Though that is probably of limited use, as the front base isn’t necessarily an existing page, and may 404 in many cases. If you’re using that value to prepend to other URLs, you’re likely … Read more

It’s highly configurable you can choose what WordPress files you want on all your WordPress sites and what you want to store separately from each other WordPress … Read more
You could filter the option requests for the host. In your wp-config.php below the line … require_once ABSPATH . ‘wp-settings.php’; … add the following lines: add_filter( ‘pre_option_home’, ‘set_current_host’ ); add_filter( ‘pre_option_siteurl’, ‘set_current_host’ ); function set_current_host() { return ‘http://’ . $_SERVER[‘HTTP_HOST’]; } add_filter() is not available earlier, and you should keep such code in your wp-config.php. … Read more
