FAQ

Installation Instructions

• Download and install using the built in WordPress plugin installer.
• Activate in the « Plugins » network admin panel using the « Network Activate » link.
• Comment out the DOMAIN_CURRENT_SITE line in your wp-config.php file. If you don’t have this line, you probably need to enable multisite.
• Start planning and creating your networks.

Can each network have a different domain?

Yes you can. That is what this plugin does best.

Think of how WordPress.org works:

• wordpress.org
• buddypress.org
• bbpress.org
• wordcamp.org

Users are global, and can login to any of those networks with the same credentials.

Will this work on standard WordPress?

You can activate it, but it won’t do anything. You need to have the multisite functionality enabled and working first.

What about multisite constants?

For maximum flexibility, use something like…

// Multisite
define( 'MULTISITE',           true                  );
define( 'SUBDOMAIN_INSTALL',   false                 );
define( 'PATH_CURRENT_SITE',   '/'                   );
define( 'DOMAIN_CURRENT_SITE', $_SERVER['HTTP_HOST'] );

// Likely not needed anymore (your config may vary)
//define( 'SITE_ID_CURRENT_SITE', 1 );
//define( 'BLOG_ID_CURRENT_SITE', 1 );

// Uncomment and change to a URL to funnel no-site-found requests to
//define( 'NOBLOGREDIRECT', '/404/' );

/**
 * These are purposely set for maximum compliance with multisite and
 * multinetwork. Your config may vary.
 */
define( 'WP_HOME',    'http://' . $_SERVER['HTTP_HOST'] );
define( 'WP_SITEURL', 'http://' . $_SERVER['HTTP_HOST'] );

What about cookies?

Use something like this to allow cookies to work across networks…

// Cookies
define( 'COOKIEHASH',         md5( 'yourrootdomain.com' ) );
define( 'COOKIE_DOMAIN',      'yourrootdomain.com'        );
define( 'ADMIN_COOKIE_PATH',  '/' );
define( 'COOKIEPATH',         '/' );
define( 'SITECOOKIEPATH',     '/' );
define( 'TEST_COOKIE',        'thing_test_cookie' );
define( 'AUTH_COOKIE',        'thing_'          . COOKIEHASH );
define( 'USER_COOKIE',        'thing_user_'     . COOKIEHASH );
define( 'PASS_COOKIE',        'thing_pass_'     . COOKIEHASH );
define( 'SECURE_AUTH_COOKIE', 'thing_sec_'      . COOKIEHASH );
define( 'LOGGED_IN_COOKIE',   'thing_logged_in' . COOKIEHASH );

Uploads?

As of version 3.5, new WordPress multisite installs use a more efficient way to serve uploaded files.
Unfortunately, this doesn’t play well with multiple networks (yet). Installs that upgraded from 3.4 or below are not affected.

WP Multi-Network needs to be running to help set the upload path for new sites, so all networks created with this plugin will have it network activated.
If you disable it on one of your networks, any new site you create on that network will store its uploaded files under that network’s main site’s uploads folder. It’s not pretty.

Just leave this plugin network-activated (or in mu-plugins) and it will take care of everything.

Can I achieve a multi-level URL path structure domain/network/site with subfolder network?

To achieve nested folder paths in this fashion network1/site1, network1/site2 etc,
please follow the steps in https://paulund.co.uk/wordpress-multisite-nested-paths to construct a custom sunrise.php (Thanks to https://paulund.co.uk for providing these steps).

Où puis-je trouver la documentation ?
