[Plugin: WP Multi Network] wp-signup.php redirect-loop

Actually I was able to fix this without hacking the core — I used a slightly modified version of the sunrise.php file that comes with
http://wordpress.org/extend/plugins/wordpress-mu-domain-mapping/

First, you must go into your wp-config.php file and uncomment or add this line:

define( 'SUNRISE', 'on' );

(I added it right after define(‘WP_ALLOW_MULTISITE’, true); )

And then create wp-content/sunrise.php and paste the following in:

<?php

if ( defined( 'COOKIE_DOMAIN' ) ) {
    die( 'The constant "COOKIE_DOMAIN" is defined (probably in wp-config.php). Please remove or comment out that define() line.' );
}

// let the site admin page catch the VHOST == 'no'
$dm_domain = $wpdb->escape( $_SERVER[ 'HTTP_HOST' ] );

if( ( $nowww = preg_replace( '|^www\.|', '', $dm_domain ) ) != $dm_domain )
    $where = $wpdb->prepare( 'domain IN (%s,%s)', $dm_domain, $nowww );
else
    $where = $wpdb->prepare( 'domain = %s', $dm_domain );

$wpdb->suppress_errors();
$domain_mapping_id = $wpdb->get_var( "SELECT blog_id FROM {$wpdb->sites} WHERE {$where} ORDER BY CHAR_LENGTH(domain) DESC LIMIT 1" );
$wpdb->suppress_errors( false );
if( $domain_mapping_id ) {
    $current_blog = $wpdb->get_row("SELECT * FROM {$wpdb->blogs} WHERE blog_id = '$domain_mapping_id' LIMIT 1");
    $current_blog->domain = $_SERVER[ 'HTTP_HOST' ];
    $current_blog->path = '/';
    $blog_id = $domain_mapping_id;
    $site_id = $current_blog->site_id;

    define( 'COOKIE_DOMAIN', $_SERVER[ 'HTTP_HOST' ] );

    $current_site = $wpdb->get_row( "SELECT * from {$wpdb->site} WHERE id = '{$current_blog->site_id}' LIMIT 0,1" );
    $current_site->blog_id = $wpdb->get_var( "SELECT blog_id FROM {$wpdb->blogs} WHERE domain='{$current_site->domain}' AND path='{$current_site->path}'" );
    define( 'DOMAIN_MAPPING', 1 );
}
?>

Yeah, I am not using the Domain Mapping plugin, I only borrowed their sunrise.php and modified it.

That sounds like a strange error message about the SUNRISE line.. there is a require_once but it’s very the last line of wp-config.php. — require_once(ABSPATH . ‘wp-settings.php’);

I have my define( ‘SUNRISE’, ‘on’ ); just above the “Authentication Unique Keys and Salts.” section.

Where do you have yours?

I’m only using the Multi-Network plugin, and I’m not mapping child blogs to domains. I’m just creating different parent domains (networks) with children under each one.

yours probably works like this:

parentdomain.com
	sub1.parentdomain.com -> otherdomain.com
	sub2.parentdomain.com -> anotherdomain.com

mine lis like this:

domain1.com
	sub1.domain.com

domain2.com
	sub1.domain2.com

Personally, I can’t really grasp why you would ever need to use the Domain Mapping plugin, now that the Multi-Network plugin is out. I have talked to another person who is using both (like you are), and I didn’t understand their reasoning. With Multi-Network, you can just directly create any number of networks (parent domains) and child sites (subdomains) under those networks.

I also want someone to be able to register on the subdomains (not the parent domains). I’m planning to set it up so that when they register on a subdomain, they’re automatically added to all the domains on that network.

I’m starting to get your point of the irrelevance of the domain mapping when you have the multi-network.
I might have to reevaluate my setup in lieu of the child site registration issue. I just might have to make it that i just have a series of networks, instead of network and child sites.
in saying that, how do you map a domain to the 2nd & 3rd network with the multi-network plugin?
my ideal situation is this

network1.com
child1.network1.com -> otherdomain.com
child2.network1.com -> anotherdomain.com

network2.com
child3.network2.com -> yetanotherdomain.com
child4.network2.com -> onemoredomain.com

with each of those child sites, a user can register to it directly without being bumped up to the network domain.

Not sure how to make that work without a lot of hacking

on more thing, if i already have a child site, and want to turn that into a network, is that possible?

right so in the end, all i had to do really was to remove the following lines from the wp-config.php for a second network to get the wp-signup.php going.

define( 'DOMAIN_CURRENT_SITE', 'memoirsite.com' );
define( 'PATH_CURRENT_SITE', '/' );
define( 'SITE_ID_CURRENT_SITE', 1 );
define( 'BLOG_ID_CURRENT_SITE', 1 );

and it seemed to all work fine. in a network, the child site still redirects to the parent for login.

Does Mult-Network plugin do domain mapping? Or is it just that you don’t see any reason to map domains?

This may be a topic for another post but I am confused by this comment by jazbek and I’m hoping to understand this better. It’s possible that I’m simply confused about how to get domain mapping working on my network and so I’m looking for evidence of my sanity.
