Expressions in filter and condition of triggers are set in definite syntax and should return logical result.
In expressions you may work with objects, which is transmitted in event. The list of available methods in objects you may see in reference book of objects.
In triggers on event «Order change» and «Customer change» there is available object
Change\EntityChangeSet). In that object there are changes made in the order/customer at the moment, and these changes are transmitted in trigger. In reference book of objects you may see available methods of this object. Read more about changes set you may in relevant article.
1. Check if the order has delivery type "Russian Post":
order.getDeliveryType() and order.getDeliveryType().getCode() == "russian-post"
2. Check if the delivery status field has been changed
3. Check if the order status has been changed to "Did not get through"
changeSet.hasChangedField("status") and changeSet.getNewValue("status").getCode() == "did-not-get-through"
4. Check if the order status group has been changed to "Complete" or "Cancel"
changeSet.hasChangedField("status") and changeSet.getNewValue("status").getGroupCode() in ["complete", "cancel"]
5. Check if the order is expired
changeSet.hasChangedField("expired") and changeSet.getNewValue("expired")
6. Check if the phone in order is specified
order.getAnyPhone() != ""
7. Check if the customer has not unsubscribed from mailing
8. Coming of new order
last_run it is possible to get information on the last trigger run. Function returns an object type
null, if trigger has not been run yet.
With that the last run is returned for the context of current events, for example for event "Order change" will be returned information on the last run of trigger for order editable at the moment.
The function takes 3 arguments, they are all optional:
interval- The maximum interval for searching.
For example, run trigger not more than once per day:
not last_run("1 day")
triggerCode- trigger code, useng this argument you can check the run of another trigger for current context.
For example. check the trigger run by code:
findByEntity- using this parameter you may change context for searching the last trigger run, for example it is useful when using parameter
triggerCode, when triggers are set on different events.
For example, conditions for trigger on event "Order change", which runs if the customer paid already the 2nd order for week
changeSet.hasChangedField("payment_status") and changeSet.getChangedField("payment_status").isPaymentComplete() and last_run("7 days", "order_pay", order.getCustomer())
Using these action you may change information on order, customer or manager when trigger runs.
For example, when order on amount of 1000 euro has been paid, the mark "VIP" should be set to the customer:
Order data change
changeSet.hasChangedField("payment_status") and changeSet.getChangedField("payment_status").isPaymentComplete() and order.getTotalSumm() > 1000
Customer data change
Expression has the same syntax with trigger condition, but as its result should be relevant value for the field, i.e. for field
Surname it should be string, for custom field of date type it should be object
Store it should be object of class
Site, for custom field of list type it should be relevant element.
For this matter in expressions for specifying of reference book data you may just specify its code (see below), also it is possible to use functions.
For using in expressions there are the same objects available like for trigger condition, for example
The fact when customer gets in the segment and the fact when customer gets out from segment are recorded to customer history, and that means these events can be catched by triggers.
Example of trigger condition for finding out if the customer get in the definite segment:
changeSet.hasChangedField('segments') and changeSet.getNewValue('segments') and changeSet.getNewValue('segments').getCode() == 'some-segment'
Example of trigger condition for finding out if the customer get out the definite segment:
changeSet.hasChangedField('segments') and changeSet.getOlValue('segments') and changeSet.getOldValue('segments').getCode() == 'some-segment'
In triggers on the missed calls there are an object
Call. Description of available methods you may see in reference book of objects. The call may have definite user, to whom the call was made
call.getManager(), the order, call is linked with
call.getOrder(), and customer, who called
call.getCustomer(). Manager, order and customer can be not specified, and it is necessary to check previously if these objects are used in trigger condition.
When creating triggers on the missed calls you may not specify filter and trigger condition. This way trigger will run on all missed calls. But there can be situations when it is necessary to process only definite categories of missed calls. There are examples of conditions for some categories below.
Call missed by user with email
call.getManager() and call.getManager().getEmailAddress() == "email@example.com"
Call missed by user from group Managers:
call.getManager() and call.getManager().isManager()
Call missed by users from group with symbolic code
call.getManager() and call.getManager().hasGroup("call-center")
Missed call from VIP-customer:
call.getCustomer() and call.getCustomer().getVip() == true
Missed call from customer with total orders amount more than 300 euro:
call.getCustomer() and call.getCustomer().getTotalSumm() >= 300
Missed call on the order with status "New":
call.getOrder() and call.getOrder().getStatus().getCode() == "new"
