从主题检查buddypress

Question

How can I check for buddypress from a theme? I've found this page for BP Plugin development

but this action never gets loaded if I hook from a theme. Why does it not work?

PS I need call some BP's functions from a theme, like: Show "BP's Activity Stream" at specific places.

What I mean with "never gets loaded" is:

(File in subdirectory of theme, and included in functions.php)

function sometestfunction() {
  exit();
}

add_action ('bp_include', 'sometestfunction');

This must make wordpress show a blank page, won't ?

Answer 1

Simple check if function 'bp_is_active' is defined:

if ( function_exists('bp_is_active') ) {
  // do something here...
}

see shanebp answer and comments.

Answer 2

this action never gets loaded

You mean never gets called? Not sure why that would be, since you don't provide any code. But it's meant for loading plugins.

If BP is installed, it is loaded by the time theme templates are parsed.

Have you tried calling BP functions in your theme? I've never had a problem doing that.

Put your function(s) in one of these places:

• a plugin
• theme/functions.php
• bp-custom.php

If your code will be used on installs you don't control, you should check for a BuddyPress component:

if( bp_is_active( 'activity' ) {
