Can't declare class for custom trigger in function.php

[cappelluti]

Problem

Hi, I need to set a custom trigger, send a notification after buttom clicked. I'm coding in function.php file of my child theme.
I tried to repeat the article https://www.smashingmagazine.com/2018/07/wordpress-notifications-made-easy and https://docs.bracketspace.com/notification/developer/triggers/custom-trigger documentation but get always the same error:

Uncaught Error: Class 'BracketSpace\Notification\Abstracts\Trigger' not found in SERVER_FOLDER/wp-content/themes/child/functions.php:777

referring the line:

class CustomTrigger extends \BracketSpace\Notification\Abstracts\Trigger {

I tried to declare so:

add_action( 'init', function() {
    class CustomTrigger extends \BracketSpace\Notification\Abstracts\Trigger {
    ...
    }
});

// Init the custom trigger class instance
add_action( 'init', function() {
    notification_register_trigger( new CustomTrigger() );
}, 1100);

but does't work.

Thank you for your help.

Same here. Can't get my custom triggers to work after updating to both WP and the Notification plugin to the latest version. They worked perfectly before updating :-( Have you found a solution yet @cappelluti ?

Unfortunately not. I tried to write in the plugin forum and directly to Bracketspace contact service but
haven't received any reply. My project is temporaly stopped.

You should also load your trigger class definition with "init" hook, but as it is mentioned in docs for registering trigger you should use "notification/elements" hook.

Based on my personal experience with this plugin i suggest you to:

1. Put your custom trigger in separate file eg. your-theme/inc/class-custom-trigger.php,

2. Add following code to your functions.php
   `add_action( 'notification/elements', function() {
   // Load trigger class
   require_once ( 'inc/class-custom-trigger.php' );

   // Register trigger
   notification_register_trigger( new CustomTrigger() );
   } );`

Thank you very much!

Thanks for the help @pewu-dev - you are totally right.

All the elements (like triggers, carriers, recipients, etc.) should be registered on the notification/elements action. Other stuff should be invoked on notification/init action.

Hi Mikita, I'm stuck developing a feature based on your Notification plugin. I thought you could help me. Tried to add an issue in Github but didn’t get any answer (#293). As I see in documentation page (https://docs.bracketspace.com/notification/developer/notifications/programmatic-notifications) I would like to add a notification (with email carrier) by code, not using WP (admin) > Notifications > Add New Notification. I have already registered in function.php my custom trigger with: add_action( 'notification/elements', function() { require_once ( 'class-my-trigger.php' ); notification_register_trigger( new MyCustomTrigger() ); }); Now, I would like to associate it to a custom notification declared in function.php. Using the sample in (https://docs.bracketspace.com/notification/developer/notifications/programmatic-notifications) I would expect to see my new notification in the list of WP notification setting page (as it happen adding custom triggers that I can associate to my notifications) but it doesn't. In particular I tried this code: add_action( 'notification/trigger/registered', function( $trigger ) { if ( 'post/updated' !== $trigger->get_slug() ) { return; } $content = ''; foreach ( $trigger->get_merge_tags( 'visible' ) as $merge_tag ) { $content .= $merge_tag->get_name() . ': {' . $merge_tag->get_slug() . '}' . "\r\n\r\n"; } notification( [ 'title' => 'My programmatic notification', 'trigger' => 'trigger_slug', 'carriers' => [ 'email' => [ 'activated' => true, 'enabled' => true, 'subject' => 'Email from ghost notification!', 'body' => 'This is nice, huh?', 'recipients' => [ [ 'type' => 'role', 'recipient' => 'administrator', ], ], ], ], 'enabled' => true, ] ); } ); Thank you.
