So, after DAYS of working on this I finally have a solution. I have not done a lot of testing, but this has worked so far.
Basically what is happening is that for forums (not replies) the logic is inverted. This means that users are subscribed to a forum unless they unsubscribe (ie. are added to the DB).
Just add this to your theme’s function.php and it should work.
I hope this helps someone, because it has taken a LOT of work!
add_filter( 'bbp_get_user_subscribe_link', 'invert_get_user_subscribe_link', 10, 4 ); //invert forum subscription
add_filter( 'bbp_is_user_subscribed_to_forum', 'invert_is_user_subscribed_to_forum', 10, 4 ); //invert forum subscription
add_filter( 'bbp_get_forum_subscribers', 'invert_get_forum_subscribers' ); //invert forum subscription
add_filter( 'bbp_is_user_subscribed', 'invert_is_user_subscribed', 10, 4 ); //invert forum subscription
function invert_is_user_subscribed($retval, $user_id, $object_id, $subscribed_ids) {
if (get_post_type( $object_id ) == bbp_get_forum_post_type())
return !$retval;
else
return $retval;
}
function strContains($needle, $haystack) {
if (strpos($haystack, $needle) !== false) {
return true;
} else {
return false;
}
}
function invert_get_user_subscribe_link ($html, $r, $user_id, $topic_id) {
if (strContains( "bbp_unsubscribe", $html )) {
$html = str_replace("bbp_unsubscribe", "bbp_subscribe", $html);
} else {
$html = str_replace("bbp_subscribe", "bbp_unsubscribe", $html);
}
return $html;
}
function invert_get_forum_subscribers( $users ) {
$args = array('fields' => 'id');
$all_users = get_users($args);
$send_to_users = array_diff($all_users, $users);
return $send_to_users;
}
function invert_is_user_subscribed_to_forum( $retval, $user_id, $forum_id, $subscribed_ids ) {
return !$retval;
}
I also include make users “subscribed” to anything they write by default. All they have to do is uncheck the box. The following code is also added to function.php.
add_action('bbp_theme_after_topic_form_subscriptions', 'subscribed_by_default'); //default subscribe
add_action('bbp_theme_after_reply_form_subscription', 'subscribed_by_default'); //default subscribe
function subscribed_by_default()
echo '<script type="text/javascript">jQuery("#bbp_topic_subscription").prop("checked","checked");</script>';
}
