Hook an action before transactional woocommerce emails are triggered/sent out

well, I tried both, and the problem is the exact same alas. The meta data doesn’t show up until a second order complete unless I add my code.

The order is not retrieved until the notification fires so it’s also not stored to the class… https://github.com/woothemes/woocommerce/blob/master/includes/emails/class-wc-email-new-order.php#L56

So as long as you’re before priority 10 you should be good.

I am priority 5, and no, it still does not work. (and it isn’t a new order I am emailing, it is a completed order)

Well, it does not matter whether I run it with woocommerce_order_status_completed or woocommerce_order_status_completed_notification, the result is identical: my new meta data is NOT found in the $item_meta->display( true, true, '_', "\n" ) string.

FWIW, Here is my final code which WILL force it to work, added to the template for email.-order-items.php

// Variation
if ( ! empty( $item_meta->meta ) ) {
$thrstring = nl2br( $item_meta->display( true, true, '_', "\n" ) );
echo '<br/><small>' . $thrstring . '</small>';
$pos = strpos($thrstring,'signup_code');
$suc = wc_get_order_item_meta( $item_id, 'signup_code' );
if($pos === false) {
//error_log("KEY does NOT exist in item_meta display string");
if ($suc) {
echo '<br/><small>signup_code: ' . esc_html( $suc ) . '</small>';
}
} else {
//error_log("KEY DOES exist and is this: $suc");
}
}

Thanks for the help anyway, I appreciate it.

one last important point:

The absence of my meta data, I have verified, is in

$item_meta->display( true, true, '_', "\n" )

Because if I print out:

echo '<pre>';
print_r($item_meta->meta);
echo '</pre>';

interestingly, my key is there at the correct time. So I believe there is a bug in the $item_meta->display() code in Woo.

Where is $item_meta defined in your case?

Here: https://github.com/woothemes/woocommerce/blob/master/templates/emails/email-order-items.php

Found it. Tis cache.

wp_cache_delete( WC_Cache_Helper::get_cache_prefix( 'orders' ) . 'item_meta_array_' . $item_id, 'orders' );

Per item ID. I’ll add a fix to clear it automatically.
