IfElse()

About this article

IfElse() is a commonly used function that outputs values based on a condition. The function is commonly used for setting a binding to certain text or setting a property based on user input. Rather than nesting IfElse() statements for multiple comparisons then use a Switch() function.

Syntax

Syntax	{{IfElse(Condition, TrueValue, FalseValue)}}
Input	Condition
Output	TrueValue/FalseValue

Example 1

Using the IfElse() function to set visibility of a binding based on the value of Form.Subject.

Binding	{{IfElse(Equals(Form.Subject, "Test"), VisibilityType.Hidden, VisibilityType.Visible)}}
Input	Form.Subject = "Test"
Condition	True
Output	VisibilityType.Hidden

Example 2

Using the IfElse() function together with FormatDateTime() to set visibility of a binding based on the value of Form.Date.

Binding	{{IfElse(Equals(FormatDateTime(Form.Date,"d-M-yyyy"), ""), VisibilityType.Hidden, VisibilityType.Visible)}}
Input	Form.Date = empty
Condition	True
Output	VisibilityType.Hidden

Because Equals can only compare fields of type text (String), you have to add FormatDateTime() to your function to set visibility based on a form field of type 'Date'.
In the example the format "d-M-yyyy" is used, but this can be any format.

Example 3

Using the IfElse() function to insert product information based on a contains() condition.

Binding	{{IfElse(Contains(Form.Subject, "Product A"), "Product A is $100", "Product B is $200")}}
Input	Form.Subject = "We are showcasing Product A"
Condition	True
Output	"Product A is $100"

Example 4

Using the IfElse() function with a checkbox to determine visibility of a binding.

Binding	{{IfElse(Form.CheckboxInclude, VisibilityType.Visible, VisibilityType.Hidden)}}
Input	Checkbox is not checked
Condition	False
Output	VisibilityType.Hidden

Example 5

Using the IfElse() function with a checkbox to determine visibility of a binding.
Show the text only if Product A and C are checked.

Binding	{{IfElse(Form.ProductA,IfElse(Form.ProductC, VisibilityType.Visible ,VisibilityType.Hidden),VisibilityType.Hidden)}}
Input	Form.ProductA = "☑", Form.ProductC = "☑"	Form.ProductA = "☐", Form.ProductC = "☑"
Output	"You have selected Product A and C"	Hidden text

Example 6

Using the IfElse() function with a checkbox to determine visibility of a binding.
Show the text only if Product A or C is checked.

Binding	{{IfElse(Form.ProductA, VisibilityType.Visible, IfElse(Form.ProductC, VisibilityType.Visible, VisibilityType.Hidden))}}
Input	Form.ProductA = "☐", Form.ProductC = "☑"	Form.ProductA = "☐", Form.ProductC = "☐"
Output	"You have selected Product A or C"	Hidden text

Example 7

Using the IfElse() function with a checkbox to determine visibility of a binding.
Show the text only if Product A and C are checked, and Product B is unchecked.

Binding	{{IfElse(Form.ProductA,IfElse(Not(Form.ProductB), IfElse(Form.ProductC,VisibilityType.Visible,VisibilityType.Hidden),VisibilityType.Hidden),VisibilityType.Hidden)}}
Input	Form.ProductA = "☑", Form.ProductB = "☐", Form.ProductC = "☑"	Form.ProductA = "☑", Form.ProductB = "☑", Form.ProductC = "☑"
Output	"You have only selected Product A and C"	Hidden text

Example 8

Using the IfElse() function with a checkbox to insert a text element (or slide).
The asset id of the text element (or slide) in the example is '123456787654321'. The function is inserted in the 'Asset Id' field:

Binding	{{IfElse(Form.Checkbox,"123456787654321","")}}
Input	Form.Checkbox = "☑"	Form.Checkbox = "☐"
Output	Text element is inserted	Text element is not inserted

If you want to insert a text element that contains form fields then use a dropdown form field to insert it. If you use a checkbox then the form fields are not shown in the composer.

Example 9

Using the IfElse() function and Not() condition for determining if the text in a form field is not equal to something.

Binding	{{IfElse(Not(Equals(Form.Subject, "Product A")), "Description of all other products", "Description of product A")}}
Input	Form.Subject = "As you can see our products are compliant"
Condition	True
Output	"Description of all other products"

Example 10

Using the IfElse() function to return a form field or HostSystem field.

Binding	{{IfElse(Equals(HostSystem.Subject, ""), Form.Subject, HostSystem.Subject)}}
Input	HostSystem.Subject = "", Form.Subject = "Hello world"	HostSystem.Subject = "Invitation", Form.Subject = "Hello world"
Output	"Hello world"	"Invitation"
