I have this project to create a multi-site buddypress network.

Users table should be shared and common to all sites in the network (same user profile for all sites in the network) but each site should have its own activity flow, groups and forums.

Any ideas? Suggestions?

Only way is to set up a multi-network WordPress site (not multi-site). Google, and/or look at http://wpmututorials.com/news/new-features/multiple-buddypress-social-networks/ for more information.

It’s still pretty new, so mightn’t be bullet proof.

@juanlopez4691 An alternative BP multinetwork plugin http://buddydev.com/plugins/buddypress-multi-network/

[@juanlopez4691 Member 12 years, 5 months ago]

Thank you very much for your suggestions. I will explore both solutions and try to decide wich one suits me best.

I am using the plugin http://buddydev.com/plugins/buddypress-multi-network/ together with BP 1.6 (trunk). Would you know how to share user across the different networks (shared user table) but have separate groups, forums etc?

I finally made up a solution adding some meta fields (blog_id, blog_path, blog_name) to groups on creation:

`function bp_group_meta_save ( $group_id ) {
$blog = get_blog_details( get_current_blog_id(), true );

$fields = array(
‘blog_id’ => $blog->blog_id,
‘blog_path’ => $blog->path,
‘blog_name’ => $blog->blogname
);

foreach ( $fields as $field => $value ) {
groups_update_groupmeta( $group_id, $field, $value );
}
}
add_action( ‘groups_created_group’, ‘bp_group_meta_save’ )`

When showing the list of groups for the current blog, I build a list with the groups with the blog_id value that matches the blog:

`function get_groups_by_meta ( $field, $meta_key, $meta_value ) {
global $wpdb;

if ( is_string( $meta_value) ) $meta_value = “‘” . $meta_value . “‘”;

$sql = $wpdb->prepare( “SELECT $field from {$wpdb->base_prefix}bp_groups_groupmeta WHERE meta_key=’$meta_key’ AND meta_value=$meta_value”, OBJECT );
$res = $wpdb->get_results( $sql );

return $res;
}

function get_groups_by_blogid ( $blog_id = 1 ) {
$list = get_groups_by_meta( ‘group_id’, ‘blog_id’, $blog_id );

if ( count( $list ) ) {
$res = ”;
foreach ( $list as $item ) {
$res .= $item->group_id . ‘,’;
}
return substr( $res, 0, -1);
} else {
return FALSE;
}
}`

And finally, in the groups-loop.php template:

`$current_blogid = get_current_blog_id();
if ( $current_blogid > 1) {
$groups_set = get_groups_by_blogid( $current_blogid );
( $groups_set !== FALSE ) ? $extra_args = ‘&include=’ . $groups_set : $extra_args = ‘&include=-1’;
}

if ( bp_has_groups( bp_ajax_querystring( ‘groups’ ) . $extra_args ) ) : ?>`

In my wp-config.php, I have defined BP_ENABLE_MULTIBLOG as true, and also a common place to upload user avatars:

`//Buddypress multi-sitio
define( ‘BP_ENABLE_MULTIBLOG’, true );

//Avatares de usuario comunes a toda la red multisitio
define( ‘BP_AVATAR_URL’, “http://mainblog/wp-content/uploads” );
define( ‘BP_AVATAR_UPLOAD_PATH’, ‘F:/xampp/www/mainblog/wp-content/uploads’ );`

I don’t know if this is a overly complicated solution. I suspect Buddypess 1.6 can deal with this situation (segregated groups, activity, forums but common user base) in a far more simple way, but I have no idea how.

Any clues?

@ juanlopez4691

Have you found any other solution or plugin dealing with this issue?

Can you share your network or websites’ url?

I am also looking for similar answers?

Thanks.

I would also like to do something like this and I am wondering if there’s an easier way to do it.

[@sapna1809 Participant 12 years ago]

Hey guys,
I just wanted to post an update to this.

@juanlopez4691 You’re a genius, the code still works! I’m running BuddyPress 1.9.1 now and it’s working smoothly. I think that you had some minor errors in your syntax though. Here’s the updated version:

bp-custom

// Add meta fields upon group creation
function bp_group_meta_save ( $group_id ) {
	$blog = get_blog_details( get_current_blog_id(), true );
	
	$fields = array(
	'blog_id' => $blog->blog_id,
	'blog_path' => $blog->path,
	'blog_name' => $blog->blogname
	);
	
	foreach ( $fields as $field => $value ) {
	groups_update_groupmeta( $group_id, $field, $value );
	}
}
add_action( 'groups_created_group', 'bp_group_meta_save' );

function get_groups_by_meta ( $field, $meta_key, $meta_value ) {
	global $wpdb;
	
	if ( is_string( $meta_value) ) $meta_value = "'" . $meta_value . "'";
	
	$sql = $wpdb->prepare( "SELECT $field from {$wpdb->base_prefix}bp_groups_groupmeta WHERE meta_key='$meta_key' AND meta_value=$meta_value", OBJECT );
	$res = $wpdb->get_results( $sql );
	
	return $res;
}

// Build a list of groups with the matching blog_id value
function get_groups_by_blogid ( $blog_id = 1 ) {
	$list = get_groups_by_meta( 'group_id', 'blog_id', $blog_id );
	
	if ( count( $list ) ) {
	$res = "";
	foreach ( $list as $item ) {
	$res .= $item->group_id . ',';
	}
	return substr( $res, 0, -1);
	} else {
	return FALSE;
	}
}

groups-loop

<?php 
$current_blogid = get_current_blog_id();

if ( $current_blogid > 1) {
$groups_set = get_groups_by_blogid( $current_blogid );
( $groups_set !== FALSE ) ? $extra_args = '&include=' . $groups_set : $extra_args = '&include=-1';
}

if ( bp_has_groups( bp_ajax_querystring( 'groups' ) . $extra_args ) ) : ?>

[@strangerstudios Participant 10 years, 7 months ago]

Hi, guys. Thanks for the thoughts and code around this idea. We are doing something similar for our setup at SchoolPress.me and I used some of the code here, tweaked it, and started a GitHub repo for the plugin.

https://github.com/strangerstudios/bp-site-groups

Instead of editing the loop in a template, I’m using the groups_get_groups filter to filter out non-site groups. I also have a couple checks in case people navigate directly to a non-site group in the frontend or dashboard.

If you have any suggestions, please open an issue at GitHub. Thanks.

As this firms up, I will probably move it into the WordPress.org repo.
