This page is for application designers who need to configure functionality for components or events. It explains the properties for the calculate node and associated expressions, which is part of an actionflow.

Overview

Use a  Calculate node to manipulate data that is passed to it. Calculate nodes have their own attributes, which can reference incoming data via expressions using one or more of the 115+ functions available in PhixFlow.

Example

Click to play the following video that shows an example of using a calculate node in an actionflow.

The video shows an actionflow that opens a new screen containing a dynamic text field. It then populates the dynamic text field with a message, which is set in a calculate node attribute. The steps for are:

1. Drag a calculate node from the toolbar and drop it into the actionflow diagram.
2. Name the calculate something meaningful, e.g. Set Message
3. Disconnect the  Open Screen node from the  Driving interface connection point.
4. Connect the  Driving interface connection point to the  Calculate node.
5. To pass data into the actionflow, go to the Inputs section on the left. Connect the component input connection point ScreenToOpen to the calculate node.
6. Click on the calculate node to open its properties.
7. In the Attributes section, add a new calculate attribute and set:
   1. Name to Message

   2. Expression to:

      "You have successfully set up a calculate node" 

8. Map the calculate attribute to the dynamic text field on the screen as follows: 

   1. Right-click on the connection and click Configure Mappings.

   2. Drag the Message attribute from the calculate node, on the left, to the Message attribute on the open screen, on the right.
   3. Close the mapping screen.
9. The actionflow configuration is complete.
