Hi there,
Thanks for reaching out. I’d be happy to help with your question.
There is not a built in way to change the automatic sku, but it is possible with some custom development. We are limited in the amount of support we can provide for customizations like this, but I may be able to get you pointed in the right direction.
The SKU is automatically generated by the Event Tickets Plus plugin. Unfortunately, there is not a filter or other way to change the pattern it uses. However, there is a filter that can enable/disable automatically generating a sku. The filter is ‘event_tickets_woo_should_default_ticket_sku’ and if you passed this “false” it would not generate the sku. You could then apply your own logic to create the sku on your own. Check out the source code to see how this is done. wp-content/plugins/event-tickets-plus/src/Tribe/Commerce/WooCommerce/Main.php starting on line 909.
It is just saving it to a post meta field. You might be able to hook into ‘event_tickets_after_woo_ticket’ (see line 1128 from the file above) and save your own custom sku there.
I hope this helps! Let me know if you have additional questions about this.
Thanks,
Sky
