Workflow Automation: Using PHP Calculations
BE CAREFUL WITH CALCULATIONS
These should only be attempted by people with programming familiarity
- You can use ( ) + - / * > < == != “
- An equal check is ==
- A not equal check is !=
- “and” is &&
-
“or” is - Use “” or NULL to unset a value depending on the field type
- Do not use $variables - insert
*field-tokens*instead - Do not add ”<?” or a semicolon to the end
- For a carriage return use “\n”
Simulate Vars can be completed using Podio data to debug complex calculations.
