Hi there,

There isn’t a way that you can run the code only for a specific event, but you can hook in and check for that event before actually doing anything.

The way I would do this is using this action hook:

do_action( 'AHEE__EE_Transaction_Processor__update_transaction_and_registrations_after_checkout_or_payment',
    $transaction,
    $update_params
);

That hook is fired whenever a transaction is updated during checkout or a payment is applied and an example of checking for a specific event can be found here:

https://gist.github.com/joshfeck/941ff81380f16e948245f8e0e6c985b6

That function first checks if the Transaction status is ‘Complete’ (‘TCM’) and then pulls the Event ID from each registration in the transaction and adds a capability, which is obviously not what you want but give you an idea of how to do it.

You could just use $primary_reg = $transaction->primary_registration(); to pull the primary registration and work with that. $update_params should also contain additional data you can use to determine if you want to create the promotion code on this request if needed.

I’ve previously created a promotion upload plugin which allows you to upload multiple promotions via CSV and again, whilst it’s not what you need it may help show how you can create promotions easily with the model system.

Take a look HERE from Line 320 onwards.

What is PRC_ID, and is it important in my model object creation? Currently I leave it undefined and it just becomes 0 in the promotion table.

PRC_ID is the ID of the price row assigned to the promotion.

If you have a PRC_ID assigned of 0, then you don’t have a price assigned to your promotion. esp_promotion stores details specific to the promotion but nothing around the price associated with that promotion (be it X value fixed/percentage etc)

Your promotion record needs a price for it to function and if you follow th code in the importer I linked to you can see how its set:

New price object created HERE.

New promotion object created HERE.

price assigned to the promotion HERE.

Without seeing your code I’m guessing you’ve missed that last line.

– What is the format for the datetime? I am asking because the end_date needs to be the transaction datetime + 2 years! Not sure how to go about this.

You should be able to use whatever DateTime format you want, as long as you tell the Model what that format is when you create the promotion. You can see how that’s done on L349 from above, HERE.

That line is expecting your Datetimes to be Y-m-d g:i a but you can change it if preferred.

Adding 2 years to now() can be done with something like:

date('Y-m-d g:i a', strtotime('+2 years'));

– Where are the names of the promotions showing up in the WP backend defined? I’d like to pass the name of the person who pays as the promotion name, and can’t see how to definite this in the Promotion table.

That’s your price name, PRC_name, again take not how that’s linked to the price object and not specifically the promotion which ties in with #1 above.

One last issue: my new promotion needs to be valid for some events only (usually category-wide).

We do not currently have a category ‘scope’ within the promotions add-on, so the promotion will either need to be global (all events) or set on specific events. Note that if you create the promotion and then add more events into the category you are using you will also need to update the promotion to apply to the ‘new’ events.

Anyway, to answer your question, your looking for how to create EE_Promotion_Object‘s

This is how the event scope creates the promotion objects for selected events:

foreach ($selected_items as $EVT_ID) {
    if (in_array($EVT_ID, $evt_ids)) {
        continue;
    }
    $promotion_obj = EE_Promotion_Object::new_instance(
        array(
            'PRO_ID'   => $promotion->ID(),
            'OBJ_ID'   => $EVT_ID,
            'POB_type' => $this->slug,
            'POB_used' => 0
        )
    );
    $promotion_obj->save();
}

$evt_ids is an array of id’s saved from looping over the promotions earlier to see which ones already apply. Take a look at \eea-promotions\lib\scopes\EE_Promotion_Event_Scope.lib.php::handle_promotion_update() for more info.

POB_type will be ‘Event’ for each of those.
