How do I enable this functionality?
After installing and activating Gravity Forms Advanced Calculations,
Add a Number field to your form. | |
Check Enable Calculation. | |
Insert advanced calculations into form. Use the Formula Cheatsheet for a primer on calculations. |
Feature Details
Merge Tag Shorthand
The true power of calculations with Gravity Forms comes from being able to reference other fields to create calculations from what users have entered. Gravity Forms uses merge tags to reference fields. Merge tags are referenced using the field ID, with or without the descriptor, such as {Field A:1}
or {:1}
.
Gravity Forms Advanced Calculations adds shorthand for fields to clean up your calculations and make it easier to keep track of everything. The shorthand for the same field shown above is written as F1
.
Shorthand offers more readable calculations, especially for complicated functions.
Conditional Statements
Advanced Calculations supports conditional statements such as if/else and if/elseif/else. Use these statements to evaluate calculations based on field values.
if/else
if( F1 > 1.25 && F1 < 5.5 ):
F1 * 50
else:
0
endif;
if/elseif/else
if( F1 < 5.5 ):
F1 * 50
elseif( F1 >= 10 ):
F1 * 25
else:
0
endif;
elseif
statements as needed. You are not limited to one.Supported Operators
The following comparison operators are supported:
==
Equal to!=
Not equal to>
Greater than<
Less than>=
Greater than or equal to<=
Less than or equal to
Multiple Expressions
Conditional statements support multiple expressions within a single condition via the the &&
(and) or the ||
(or) operators.
To require both expressions to be true for the condition to match, you would use the &&
operator. In this example, the condition will only be true if Field #1 is greater than 5 and less than 10.
if ( F1 > 5 && F1 < 10 ):
If you would like your condition to match if any of the conditions are true, you would use the ||
operator. In this example, the condition will return true if Field #1 is greater than 5 or if Field #2 is greater than 5.
if ( F1 > 5 || F2 > 5 ):
While these examples are simple, this functionality is quite robust and can handle conditions that contain expressions with both &&
and ||
operators.
Syntax Highlighting
Advanced Calculations adds syntax highlighting and autocompletion to the calculation text area. Syntax highlighting drastically improves the readability of calculations, especially complicated ones that use conditional statements and functions.
Autocompletion aids you when inputting a function or conditional statement. When you start typing any supported function, the editor will suggest a completion. Click the suggested function (or hit return) to insert the full function with placeholder values.
The editor also automatically closes parentheses and merge tag braces. Say goodbye to invalid formulas because of an errant parenthesis!
Tooltips
When hovering over shorthand field variables and merge tag field variables with no descriptor in the formula editor, you will see a tooltip displaying the field’s label.
Functions
Advanced Calculations adds support for common functions to both save you time and effort and provide more accurate results.
Exponential – exp
Returns e^x, where e is Euler’s number (~2.718) and x is the provided value.
Future Value – fv
fv
calculates the future value of an investment based on constant-amount periodic payments and a constant interest rate.
Natural Logarithm – ln
ln
returns the logarithm of a number, base e. e is Euler’s number (~2.718).
Known Limitations
- Non-numeric values are not supported in conditional statements.
