Hi Juan,

At this time there isn’t a Messages shortcode that prints the promotion code that was used at checkout. I can put in a feature request for this. If this is something you need added sooner than later, I can suggest contacting one of the recommended developers for a quote:

Hi Juan,

Please do not edit core files, we can not provide support if you edit the core files and generally have a filter available to edit/add the functionality in most places within Event Espresso (as we do for adding custom messages shortcodes). If a filter is not available we are more than happy to request one is added to allow you to modify what you need.

So with the Messages system we have a filter hook available that can be used to add your own custom shortcodes, that filer is ‘FHEE__EE_Shortcodes__parser_after’

Take a look here for an example of how to use is:

https://gist.github.com/Pebblo/e87cc8e30c4848dcdfe2

You’ll want to add the shortcode to the EE_Transaction_Shortcodes.

When parsing the shortcode you’ll have the EE_Transaction object passed in as $data.

The promo codes are stored as line items assigned to the transaction, I do not believe there is a ‘promotion code’ property you can access from EE_Payment, but if you take a look at the add_promotions_column_to_reg_csv_report() method within EED_Promotions class you can see how the promotion code is pulled in from database and added to the CSV, you do do almost the same within the shortcode and output a list of Promo codes that apply to the transaction.

I realised, the $data object passed to the parser is not the EE_Transaction object.

It will be an EE_Messages_Addressee object, from that you can get the transaction using something like:

$transaction = $data->txn;
