## Description

Per default, bbPress is sending subscription notification emails as one email with
a bunch of BCCs. There are various reasons why it would make more sense to send 
individual emails. This plugin does that, quietly in the background via WP cron,
without slowing down page load times. Also increases notification performance and
reduces database load on large sites.

#### Defaults

If you don’t customize this plugin, this is what you’ll get:

 * Sends mails from `"MyBlog <admin@MyBlog.foo>"` (with your Blog’s name and admin
   email)
 * Sends mail to `"Markus <markus@example.com>"` (with the name being the user’s
   display name on the forums, not their username)
 * Subject and Message have more user friendly defaults, use the available filters(
   see below) to make them your own.

#### Customization

You can install and activate this plugin and it just works, but you have full control
over the details if you want to. Below are some filters and code snippets that help
you do what you want. If you’re new to working directly with code, please see the
example at the bottom of this page.

#### Available filters

    ```
    bbp_subscription_email_from( $from ) // $from can be a string or array('name'=>string, 'address'=>string)
    bbp_subscription_email_recipients( $recipients ) // $recipients is array of array('name'=>string, 'address'=>string)
    bbp_subscription_email_headers( $headers )
    bbp_forum_subscription_email_subject( $subject, $forum_id, $topic_id )
    bbp_forum_subscription_email_message( $message, $forum_id, $topic_id )
    bbp_topic_subscription_email_subject( $subject, $forum_id, $topic_id, $reply_id )
    bbp_topic_subscription_email_message( $message, $forum_id, $topic_id, $reply_id )

    bbp_bounce_address( $bounce_address )

    bbp_subscription_disable_async( false )
    bbp_forum_subscription_disable_async( false )
    bbp_topic_subscription_disable_async( false )
    bbp_forum_subscription_notify_author( false )
    bbp_topic_subscription_notify_author( false )
    ```

#### Helpful Snippets

Here are some pointers to get the data you might want in your notifications:

    ```
    $blog_name = get_bloginfo( 'name' );

    $forum_title = bbp_get_forum_title( $forum_id );

    $topic_author_user_id = bbp_get_topic_author_id( $topic_id );
    $topic_author_display_name = bbp_get_topic_author_display_name( $topic_id );
    $topic_title = wp_specialchars_decode( strip_tags( bbp_get_topic_title( $topic_id ) ), ENT_QUOTES );
    $topic_content = wp_specialchars_decode( strip_tags( bbp_get_topic_content( $topic_id ) ), ENT_QUOTES );
    $topic_url = get_permalink( $topic_id );

    $reply_author_user_id = bbp_get_reply_author_id( $reply_id );
    $reply_author_display_name = bbp_get_topic_author_display_name( $reply_id );
    $reply_content = strip_tags( bbp_get_reply_content( $reply_id ) );
    $reply_url = bbp_get_reply_url( $reply_id ); // note that it's not get_permalink()
    ```

#### Example

To have a nice subject line for new topic notifications, add this to your theme’s`
functions.php`. If your theme does not have this file, you can simply create it 
and it will be loaded automatically. Note how the example is basically just one 
of the filters above, mixed with some of the snippets and a return statement. It’s
that simple.

    ```
    add_filter( 'bbp_forum_subscription_email_subject', function( $subject, $forum_id, $topic_id ) {
        $blog_name = get_bloginfo( 'name' );
        $topic_author_display_name = bbp_get_topic_author_display_name( $topic_id );
        $topic_title = wp_specialchars_decode( strip_tags( bbp_get_topic_title( $topic_id ) ), ENT_QUOTES );
        return "[$blog_name] $topic_author_display_name created a new topic: $topic_title";
    }, 10, 3); // first is priority (10 is default and just fine), second is number of arguments your filter expects
    ```

## FAQ

### No emails are being sent

If other WP emails work normally try adding `define('ALTERNATE_WP_CRON', true);`
to your `wp-config.php`

### Can I use real cron instead of WP cron?

Yes. Add `define('DISABLE_WP_CRON', true);` to your `wp-config.php` and have a real
cron job execute e.g. `wget -q -O - http://your.blog.example.com/wp-cron.php >/dev/
null 2>&1`

 [strike3](https://profiles.wordpress.org/strike3/) August 7, 2017

We have a lot of users on our forum. BBPress notifications were not going out because
we were over our hosting limits for email. Among other things, this plugin forces
BBPress to send a separate email to each user (instead of one massive email that
BCCs all subscribers). We combined this with a email queue plugin, and now we are
sending out emails to hundreds of users and staying under our hosting provider’s
email limits. Woohoo!

 [cfk4spk](https://profiles.wordpress.org/cfk4spk/) September 3, 2016

This plugin absolutely fixes the “issues” that bbPress created when they switched
to their bcc setup for subscribing to forums and topics! bbPress bcc idea has its
positive side, but it also has a negative side, in that it “breaks” some mailing
service systems. AsynCRONous bbPress Subscriptions FIXES that! This plugin NEEDS
to be incorporated into bbPress core! This is the way the subscriptions should work—
in the first place!! And the author’s support of this plugin could not be better!
THANK YOU, Markus!!!

By default, the bbPress forum reply notification emails were not being delivered
to any forum subscribers. This plugin fixed that, immediately. Upon installing the
plugin, the reply notification emails will just work.
