Reference the values in Magic Variables for use in your PMQL queries. Furthermore, reference Magic Variables in Scripts and Screens during in-progress Requests.

Overview

ProcessMaker Platform uses a set of Magic Variables that you may reference in ProcessMaker Query Language (PMQL) queries and in your ProcessMaker assets, such as Scripts and Screens.

ProcessMaker Platform uses a schema-less JSON data model from which to read, write, and store Request data. Since the JSON data model is schema-less (meaning that it does not require a specific schema or structure from which ProcessMaker Platform assets must conform), the JSON data model is structured from the JSON objects in assets used in a Request: the Variable Name setting values in a Screen or Request variables a Script creates. When an in-progress Request routes through the Process, Request data aggregates into the JSON data model, thereby becoming Request data.

However, ProcessMaker Platform uses a set of Magic Variables that become part of the JSON data model for all Requests. ProcessMaker Platform uses these Magic Variables to store user, Process, and Request related data for all Requests. During an in-progress Request, these Magic Variables are updated. All Magic Variables are preceded by an underscore (_) character in the JSON data model.

Users that have the Requests: Edit Request Data permission may view the JSON data model for a completed Request. This JSON data model displays from the Data tab in a completed Request's summary. Below is an example.

How to Use Magic Variables

Use Magic Variables in a variety of ways in ProcessMaker Platform and in ProcessMaker Platform assets.

Reference in PMQL Queries for Request and Task Searches

Reference Magic Variables to compose ProcessMaker Query Language (PMQL) advanced queries for Request searches and Task searches. See the following topics:

Mock in Script Testing

Your user account or group membership must have the following permissions to edit a Script unless your user account has the Make this user a Super Admin setting selected:

  • Scripts: Edit Scripts

  • Scripts: View Scripts

See the Scripts permissions or ask your Administrator for assistance.

Mock Magic Variable values while mocking Request data during testing to ensure your Script runs as you intended.

Reference in Screens

Your user account or group membership must have the following permissions to edit a Screen control unless your user account has the Make this user a Super Admin setting selected:

  • Screens: Edit Screens

  • Screens: View Screens

See the Screens permissions or ask your Administrator for assistance.

Reference Magic Variables in Screens in the following ways:

Example of All Magic Variables

Below is an example that contains all Magic Variables. Each contains a value as it might be read from the Data tab in a completed Request summary. This example indicates the JSON structure for each Magic Variable.

Magic Variable Descriptions

Below are descriptions of each Magic Variable. Since these descriptions are outlined in tabular format, they do not imply how they are structured in the JSON data model. Refer to the example in the Example of All Magic Variables section to see how each JSON object is structured in the overall JSON data model.

_user Magic Variable

The _user Magic Variable contains data about the current user assigned a Form Task element or Manual Task element during an in-progress Request. Use JSON dot notation to reference specific data in a Magic Variable. Example: _user.fullname. If a Magic Variable contains no data, null is the value.

The following table documents the _user Magic Variable names in the order they present within the JSON object.
