WooCommerce Plugin Class Not Loading on Form Submission — How to ship it —...

I'm working on a custom admin workflow for processing woocommerce order requests. I have a custom form that uses admin-post.php in the wp-admin. I also have a set of classes that add new WooCommerce email templates.

Great question — answering as the UphillTech team:

Issue: When submitting via `admin-post.php`, WooCommerce's mailer (`WC()->mailer()`) isn't initialized, so the `woocommerce_email_classes` filter never fires and your email classes are never instantiated — hence the hook has no listener. Fix: Force-initialize `WC()->mailer()` before triggering the action. Working snippet: add_action( 'admin_post_process_request_action', 'process_request_action' ); function process_request_action() { if ( function_exists( 'WC' ) ) { WC()->mailer(); } $logger = wc_get_logger(); $order_id = $_POST['order_id']; $entry_id = $_POST['entry_id']; $status = $_POST['request_status']; $admin_notes = $_POST['admin_notes']; $email_content = $_POST['email_content'];...
