Hi EventON team,
I’m experiencing a critical issue with the EventON Tickets + PDFer workflow when WooCommerce orders are automatically completed via payment gateway callback (Quickpay).
Summary of the issue
When an order is automatically set to “completed” by the payment gateway callback, the EventON ticket email is NOT sent, and the PDF is not generated.
When I manually change the order status to Completed, the ticket email IS sent correctly, including the PDF attachment.
This means EventON behaves differently depending on how the status is changed.
Important details
The issue only occurs when PDFer’s “generate PDF” option is enabled.
If I disable PDF generation in PDFer settings, the EventON ticket email is sent correctly even with auto-complete enabled.
When the PDF generation is enabled, WordPress throws a fatal error from the PDFer plugin and stops the entire ticket email process.
WordPress recovery mode reports a plugin crash coming from EventON – PDFer.
(Let me know if you need the exact error file/line — I can send it.)
Environment
WordPress 6.8.3
WooCommerce (latest version)
EventON (latest version)
EventON Tickets (latest version)
EventON PDFer (latest version)
PHP 8.1 (previously 8.4 — same issue on both)
Quickpay payment gateway (auto “order completed” callback)
What I need
I need a stable way for orders to be automatically completed (via payment gateway callback) and still have:
EventON generate tickets
PDFer generate the PDF file
EventON send the ticket email with the PDF attached
This is essential because I will be selling thousands of tickets per month, and manual completion is not an option.
What to know
The auto-complete process works perfectly when PDFer is disabled.
The problem only occurs when PDF generation is involved.
This strongly suggests a timing/ordering bug in PDFer when WooCommerce order status changes automatically.
Please help with one of the following:
A fix for PDFer so it doesn’t crash during auto-complete status changes
A recommended code snippet or hook order to trigger PDF creation before sending the ticket email
Any known compatibility issues with PDFer and Woo auto-complete/payment gateway callbacks
Thanks in advance — this feature is critical for our ticketing business.
Best regards, Rasmus
