BuddyPress.org

I created a plugin that adds a Call button to the profile page. With Buddypress 2.0.1 it worked, but when I updated to 2.1.1 the button disappeared from the profile page.

This is the code that adds the button :

function videocall_get_slug() {
global $bp;
return $videocall_slug = isset( $bp->videocall->slug ) ? $bp->videocall->slug : ”;
}

function videocall_is_user_online( $user_id ) {
if ( bp_has_members( ‘type=online&include=’. $user_id ) ) {
return true;
} else {
return false;
}
}

function videocall_get_video_chat_link() {
return bp_loggedin_user_domain() . videocall_get_slug() . ‘/call?user=’.bp_displayed_user_id().’&id=’ . rand()
}

function videocall_invite_button() {

if ( videocall_is_user_online( bp_displayed_user_id() ) ) {
$link_class = ‘start-videocall online';
} else {
$link_class = ‘start-videocall';
}

bp_button( array(
‘id’ => ‘videocall’,
‘must_be_logged_in’ => true,
‘block_self’ => true,
‘wrapper_id’ => ‘videocall’,
‘link_href’ => videocall_get_video_chat_link(),
‘link_title’ => __( ‘Video call with this user.’, ‘videocall’ ),
‘link_text’ => __( ‘Video call’, ‘videocall’ ),
‘link_class’ => $link_class,
) );
}
add_action( ‘bp_member_header_actions’, ‘videocall_invite_button’,99);

With WordPress 4.0 and Buddypress 2.0.1 it workes just fine.
Any suggestions?
