Class 'WP_Background_Process' not found

[CNSam]

Hi there,

I am currently using the Wordpress Plugin Boilerplate (https://github.com/DevinVinson/WordPress-Plugin-Boilerplate) to build a plugin as I have many times before however now have a requirement for background processing.

I am also using woocommerce and what im wanting to do is upon payment complete is push the order to our warehouse management system but do this as a background task as opposed to taking up the time on the user-facing side.

Unfortunately when I am running through a test transaction I am constantly receiving

Class 'WP_Background_Process' not found in WCKhaos/includes/tasks/SendOrderTask.php on line 3

Have you any experience with WooCommerce, WPPB and your plugin or any advice so I can look further?

Thanks in advance

WP_Background_Process is actually included in WooCommerce, see:

https://github.com/woothemes/woocommerce/blob/master/includes/libraries/wp-background-process.php

What does your code look like?

Hi Ashley,

Thanks for your response - I think i've fathomed the inclusion of the file out, however I cannot for the life of me work out why the tasks aren't being ran:

I have this within my plugin:

        $this->loader->add_action( 'woocommerce_order_status_changed', $khaos_order, 'process_order_for_queue');

The `process_order_for_queue' function looks like:

public function process_order_for_queue( $order_id )
    {

        $order_id = '114';
        $queue = new SendOrderTask();
        $queue->push_to_queue($order_id);
            $queue->save();
            $queue->dispatch();
    }

What am I missing here, there seems to be a number of "wp_khaos_orders_batch_fed9ebb241fa503030fd6debd282d73a" within the options table but nothing is actually firing?

Are you able to manually hit wp-admin/admin-ajax.php? Is the site behind basic auth?

[CNSam]

Yep, can hit that absolutely fine, I've managed to dump out the url that is generated: /wp-admin/admin-ajax.php?action=wp_khaos_orders&nonce=5d91a7bdaa

Also, If I var_dump the $queue->dispatch() call im getting the following:

array (size=5)
  'headers' => 
    array (size=0)
      empty
  'body' => string '' (length=0)
  'response' => 
    array (size=2)
      'code' => boolean false
      'message' => boolean false
  'cookies' => 
    array (size=0)
      empty
  'http_response' => null

Anything to go on here?

* UPDATE* I've installed the example plugin and that all seems to work absolutely fine - seriously at a loss, im just wondering if it has something to do with the ordering of the initialisation of the Wordpress Plugin Boilerplate

Closing this rather old support issue, if by some miracle this is an outstanding issue, please comment.
