Buddypress – Check if a user is online

I’d also be interested to know how scalable BuddyPress is…? Never really tested it past a few thousand members.

This is my working new tab in bp-custom.php if this helps

// Set up Custom BP navigation
function my_setup_nav() {   
   if ( user_can( bp_displayed_user_id(), 'job_applicant' ) ) {  
   global $bp;
      bp_core_new_nav_item( array(
            'name' => __( 'Portfolio', 'buddypress' ),
            'slug' => 'portfolio',
            'position' => 20,
            'screen_function' => 'profile_screen_portfolio' 
      ) );

      // Change the order of menu items
      $bp->bp_nav['messages']['position'] = 100;
  }
}

add_action( 'bp_setup_nav', 'my_setup_nav' );

// show portfolio when 'Portfolio' tab is clicked
function profile_screen_portfolio() {
add_action( 'bp_template_content', 'profile_screen_portfolio_show' );
bp_core_load_template( 'members/single/plugins' );
}

function profile_screen_portfolio_show() {

// call your stats template
locate_template( array( 'portfolio-profile.php' ), true );

}

If you have made a child theme you could use this tutorial and it limits friends to view your profile.
http://wpmu.org/how-to-add-profile-privacy-to-buddypress/
Other than that then you are limited to the premium plugins listed above. I have tried the plugin I recommended and it works.

i had the same problem. there was a conflict in some themes, but others not. in my case i changed all instances of “jQuery” to “jq” in the easing function (line 1540) in the file buddypress/bp-templates/bp-legacy/js/buddypress.js

Try these changes:

	'parent_url'      => $bp->loggedin_user->domain . '/',
	'parent_slug'     => $bp->profile->slug,

Yep this is an issue we’re aware of I did a little work on username reg process in core but this aspect is tricky and needed to be re-visited separately:
https://buddypress.trac.wordpress.org/ticket/4939

I had a similar problem of none of the pages showing, even with the default buddypress theme and registration enabled. The pages showed the template, but no buddypress content.

I fixed the problem by setting each page as its own parent page. As a child page, the members, group, etc did not work. As a parent page, they did.

Hope this helps!

I had the exact same problem. I solved it by redirecting users to their profile page upon login by adding the code below (which I found here: http://buddydev.com/buddypress/buddypress-trick-redirect-users-to-their-profile-on-login/) to functions.php

/*let us filter where to redirect */
 
add_filter("login_redirect","bpdev_redirect_to_profile",10,3);
 
function bpdev_redirect_to_profile($redirect_to_calculated,$redirect_url_specified,$user)
{
if(empty($redirect_to_calculated))
$redirect_to_calculated=admin_url();
 
/*if the user is not site admin,redirect to his/her profile*/
if(!is_site_admin($user->user_login))
return bp_core_get_user_domain($user->ID );
else
return $redirect_to_calculated; /*if site admin or not logged in,do not do anything much*/
 
}

Try my plugin Rename wp-login, it does exactly what you want.

I’ve had great success using w3totalcache with most everything selected except page caching.

And I always use the memcached option – so you have to have memcache set up across all your servers.

Involves a lot of fiddling – but worth it for installs with tens of thousands of members.

No you don’t cache DB stuff you do cache static objects, caching dynamic data will cause issues and BP draws heavily on DB tables.

tbh caching plugins with WP seem to be more hassle than they are worth, cause of loads of issues. Always considered caching a server aspect really and/or offloading static stuff to CDN.

w3totalcache is a very powerful plugin.
And it’s essential to use a caching plugin on large BP installs.
But don’t use page caching with any plugin or you will get stale pages and other issues.

And you’ll have to carefully tune the plugin settings for your particular install and hosting.
It can be quite complicated. But once you get it right, the difference is dramatic.
