WWD Comment Notifier

Developed with ♥ by whatwedo(https://whatwedo.ch) in Bern

Note: This plugin was initially written in 2019 and used on a production site for 6 years. The client doesn't need the functionality anymore, but we thought it could still be useful or an inspiration for some people.

We don't maintain this code for future changes, but it was working up the following system requirements as of May 2025:

• WordPress 6.8
• PHP 8.4

Config

The plugin is shipped without any option page in WordPress. To configure the plugin use the JSON file in the config folder. This is a stateful and developer friendly way to customize the plugin.

Copy the config file within the config directory and adjust the content for your preferences. Add the custom config to your theme and use the following hook to register it:

add_filter('wwdcn_config_path', function () {
    return get_template_directory() . '/config/custom-notifier-config.json';
});

Variables

Defined variables in JSON file are not optional.

1. name (string)
2. mail (object)
3. subject (string)
4. content (string: Multilines are solved with an array structure [])
5. from_address (string)
6. excerpt_length (int)
7. checkbox (object)
8. label (sting)
9. default_state (int)
10. unsubscribe (object)
11. title (string)
12. text (string)
13. url (string: / = homepage, false = subscriped post url)
14. redirect_url (bol/string: false = dies and then redirects, set custom url here if you want to handle it differently)
15. redirect_time (bol/string: just works when redirect_url is set to false)
