Using data between step attributes

A step triggered event uses only data that is contained in the step in which it is triggered, which is a similar behavior to how hits are triggered.

To use data from step 1 in step 2, you must record the data from step 1 in an event and then reference the event in step 2.

For example, suppose your request data for a single hit looks like:

[appdata]
TLT_URL=/tealeaftarget.php
TLT_CUI_URL= /checkout

[StepAttributes]
                {
                    "type": 4,
                    "offset": 8063,
                    "count": 1,
                    "event": {
                        "type": "change"
                    },
                    "target": {
                        "id":  firstname",
                        "idType": -1,
                        "type": "INPUT",
                        "dwell": 2196,
                        "currState": {
                            "value": "MyName"
                        }
                    }
                },
                {
                    "type": 4,
                    "offset": 2293,
                    "count": 2,
                    "event": {
                        "type": "click"
                    },
                    "target": {
                        "id": "login:guest",
                        "type": "INPUT",
                        "subType": "radio",
                        "currState": {
                            "checked": true,
                            "value": "guest"
                        }
                    }
                },

In the preceding data:

• [appdata] data is available through standard hit attributes.
• There are 2-step messages:
  • Step 1: The first step identifies the change client event, in which the firstname form field is set to MyName.
  • Step 2: The second step identifies the click client event, in which the login.guest element is set to guest.

A single step-triggered event cannot use data from both step 1 and step 2 at the same time. For example, you cannot create a step-triggered event that fires on the click message and records the value of the firstname value by using only step attributes.

To capture the value of Step 1 based on the condition of Step 2, you must:

• Create a step attribute to capture firstname's value on Step 1.
• Create an event that records the value of the step attribute for Step 1.
• Create an event that fires on the click for guest and uses the value for the Step 1 event for the guest value.
