how to customize order id

Hi

you cannot do that at the moment, but the next version will have a filter you can use in your functions.php file like so:

add_filter('wppizza_custom_transaction_id', 'my_custom_transactionid_filter',10,2);
function my_custom_transactionid_filter($transactionId,$orderId){
	/**prepend 1234 for example***/
	$transactionId='1234-'.$transactionId;

	return $transactionId;
}

PS

this filter will NOT write to or change entries in the database, it will only change the display of how you want to display the transaction id

should now work with v 2.9.4.3
