BuddyPress.org

To create a member only site, I would highly recommend this plugin – https://wordpress.org/plugins/jonradio-private-site/

1.) For invites try: https://wordpress.org/plugins/wordpress-mu-secure-invites/
To keep logged out visitors from accessing BP pages check out: http://bphelpblog.wordpress.com/2014/09/27/private-bp-pages/
Usernames can’t be changed and if you don’t want users changing their password you would need to custom code it unless you can find a code snippet on the forum or on the net.
2.) You can use filters and you can also try this plugin: https://wordpress.org/plugins/bp-profile-search/
3.) Use bbPress: https://wordpress.org/plugins/bbpress/
You will have to search the plugins directory, the forums, and google the rest for your requirements unless someone else would like to take over where I left off. Hope this is at least a start. Good luck!

Here’s a snippet to filter members list based on profile field.

Remove your custom members-loop file first and revert to default one.

The example use field ID 62 with value = public
The field is called Privacy in xProfile and use a selectbox field type who shows 2 options: private and public.

You’ll probably also have to remove, or to conditionnally show, the top navbar, search box, etc in the template (childtheme/buddypress/members/index.php)

Add this snippet to bp-cutom.php.

class BP_Custom_User_Ids {
	private $custom_ids = array();
	public function __construct() {
		$this->custom_ids = $this->get_custom_ids();
		add_action( 'bp_pre_user_query_construct', array( $this, 'custom_members_query' ), 1, 1 );
		add_filter( 'bp_get_total_member_count', array( $this, 'custom_members_count' ), 1, 1 );
	}
	
	private function get_custom_ids() {
		global $wpdb;
		// collection based on an xprofile field
		$custom_ids = $wpdb->get_col("SELECT user_id FROM {$wpdb->prefix}bp_xprofile_data WHERE field_id = 62 AND value = 'Public'");
		return $custom_ids;
	}	
	
	function custom_members_query( $query_array ) {
		$query_array->query_vars['include'] = $this->custom_ids;
	}	
	
	function custom_members_count ( $count ) {
		$new_count = count( $this->custom_ids );
		return $count - $new_count;		
	}
}

function custom_user_ids( ) {
	new BP_Custom_User_Ids ();
}
add_action( 'bp_before_directory_members', 'custom_user_ids' );

Hi @callumoberholzer

BuddyPress allows you to have:

• member profiles
• an advanced member search (through the BP Profile Search plugin)
• private messaging

So it looks like your requirements are covered. My advice would be to set up a test install and try out all of the features to see if they meet your requirements.

Ah sorry, by PM I thought you may have been referring to public messaging (also known as @-mentions). Auto-complete should work on the private messaging compose screen too. Have you tested?

Short of giving your users extra hugs and re-assuring them that their WordPress usernames aren’t particularly private bits of data, you’re going to have to get your hands dirty. 🙂

It might be down to how the other plugin creates user accounts. Most plugins that allow sign-in using other services’ authentication systems (such as Facebook) don’t “properly” create WordPress user accounts; they use MySQL statements directly instead of using WordPress’ APIs.

This can cause problems with plugins that expect certain user record fields to be in a particular format (if some other plugin came along and just inserted something in a custom format in place). I am not saying that this is the case with this plugin, as I haven’t looked at its code, but I’ve seen this sort of thing before.

If you can create a test account and then go into your DB’s wp_users table and find your test user, and let us know what the values of the user_login, user_nicename, display_name fields are — and which one of these @mentions is using, and which one you would like it to use.

I built @mentions in the last BuddyPress release and while I’m not sure if it’s possible to get it to change how it behaves like this, understanding what you’d want different with real data from a test account will help us help you, and at worse, give a suggestion for ways we could make advanced customisations possible for this in future BuddyPress releases.

I have a premium plugin Private Community For BP that should do what you need if you are interested. You can ask any questions regarding this plugin you have here:

@vernontessio,

it depends on how you use bbpress ! As standalone forum or as group forum.

If you use buddypress’s group forums, you create a hidden group which will be only seen by the members who belongs to it and nobody else.

If you use bbpress outside of BP as standalone forum, you can use Private Groups plugin.

Remember also that Everything in a BuddyPress community revolves around its members.

So you created a private group call ‘vip’.
And added a forum to that group via ‘[your-site-url]/groups/vip/admin/forum/’
And added some members to the forum via
wp-admin/admin.php?page=bp-groups -> Edit – Add New Members

And those added members cannot see the vip forum listed when visiting
‘[your-site-url]/forums/’ – correct?
