What is the IfElse() function? 

IfElse() is a commonly used function that outputs values based on a condition. The function is commonly used with smart fields (with the binding syntax or the visibility), and can also be used with template settings and properties.

 

IfElse() logic

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

 

Rather than nesting multiple IfElse() statements for multiple comparisons, we recommend Switch() or And() and Or() functions instead.

 

IfElse() function examples

• Example 1 - Set visibility based on value of a text form field
• Example 2 - Set visibility based on value of a date form field
• Example 3 - Set visibility based on value of a number form field
• Example 4 - Show specific text as output based on if it equals the value of a number form field
• Example 5 - Show specific text as output based on if it contains the value of a text form field
• Example 6 - Show specific text as output based on if it equals the value of a text form field (nested)
• Example 7 - Show specific text as output based on if it not equals the value of a text form field
• Example 8 - Set visibility based on value of a checkbox form field
• Example 9 - Set visibility based on value of checkbox form fields A and C
• Example 10 - Set visibility based on value of checkbox form fields A or C
• Example 11 - Set visibility based on value of checkbox form fields A and C (not B)
• Example 12 - Set visibility based on if user profile field contains specific value
• Example 13 - Dynamically insert text element or slide based on value of a checkbox form field
• Example 14 - Show value of text form field if HostSystem field is empty

 

Example 1

Using the IfElse() function to set the visibility of a smart field based on the value of the 'Subject' question originating from the response form.

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

 

Example 2

Using the IfElse() function together with FormatDateTime() to set the visibility of a smart field based on the value of the 'Date' question (of type Date) originating from the response form.

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

 

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 together with FormatNumber() to set the visibility of a smart field based on the value of the 'Number' question (of type Number) originating from the response form.

Binding	{{IfElse(Equals(FormatNumber(Form.Number,"#"), "1"), VisibilityType.Hidden, VisibilityType.Visible)}}
Input	Form.Number = "1"	Form.Number = "123"
Condition	True	False
Output	Hidden text	Visible text

 

Because Equals() can only compare fields of type text (String), you have to add FormatNumber() to your function to set visibility based on a form field of type Number. Use this binding in the Visibility Expression field to configure a Custom visibility. Use the format '#'.

 

Example 4

Using the IfElse() function together with FormatNumber() to set the visibility of a smart field based on the value of the 'Number' question (of type Number) originating from the response form.

Binding	{{IfElse(Equals(FormatNumber(Form.Number,"#"), "1"), "Hello world", "The quick brown fox jumps over the lazy dog")}}
Input	Form.Number = "1"	Form.Number = "123"
Condition	True	False
Output	"Hello world"	"The quick brown fox jumps over the lazy dog"

 

Because Equals() can only compare fields of type text (String), you have to add FormatNumber() to your function to set visibility based on a form field of type Number. Use this binding in the Binding field. Use the format '#'.

 

Example 5

Using the IfElse() function together with Contains() to inject specific product information in the smart template based on the 'Subject' question (of type Text) originating from the response form.

Binding	{{IfElse(Contains(Form.Subject, "Product A"), "Product A is $100", "Pricing list available upon request")}}
Input	Form.Subject = "We are showcasing Product A"	Form.Subject = "We are showcasing different products"
Condition	True	False
Output	"Product A is $100"	"Pricing list available upon request"

 

Example 6

Using the IfElse() function to show the correct salutation depending on the HostSystem value of 'Gender'.

Binding	{{IfElse(Equals(HostSystem.Gender, "M"), "Dear sir", IfElse(Equals(HostSystem.Gender, "F"), "Dear madam", "Dear sir/madam"))}}
Input	HostSystem.Gender = "M"	HostSystem.Gender = "F"	HostSystem.Gender = ""
Output	"Dear sir"	"Dear madam"	"Dear sir/madam"

 

Instead of using a nested IfElse() binding as shown above, you can also use the Switch() function in this case (see example 2 in that article).

 

Example 7

Using the IfElse() function together with Not() and Equals() to inject specific product information in the smart template based on the 'Subject' question (of type Text) originating from the response form.

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"	Form.Subject = "Product A"
Condition	True	False
Output	"Description of all other products"	"Description of product A"

 

Example 8

Using the IfElse() function to set the visibility of a smart field based on the value of the 'CheckboxInclude' checkbox question (of type Checkbox) originating from the response form. 

Binding	{{IfElse(Form.CheckboxInclude, VisibilityType.Visible, VisibilityType.Hidden)}}
Input	Form.CheckboxInclude = "☑"	Form.CheckboxInclude = "☐"
Condition	True	False
Output	Visible text	Hidden text

 

Example 9

Using the IfElse() function together with the And() to set the visibility of a smart field based on the value of two checkbox questions originating from the response form, 'Product A' and 'Product C' must both be checked for the text to be visible.

Binding	{{IfElse(And(Form.ProductA, Form.ProductC), VisibilityType.Visible, VisibilityType.Hidden)}}
Input	Form.ProductA = "☑" Form.ProductC = "☑"	Form.ProductA = "☐" Form.ProductC = "☑"
Condition	True	False
Output	Visible text	Hidden text

 

Example 10

Using the IfElse() function together with the Or() to set the visibility of a smart field based on the value of two checkbox questions originating from the response form, 'Product A' or 'Product C' must be checked for the text to be visible.

Binding	{{IfElse(Or(Form.ProductA, Form.ProductC), VisibilityType.Visible, VisibilityType.Hidden))}}
Input	Form.ProductA = "☐" Form.ProductC = "☑"	Form.ProductA = "☐" Form.ProductC = "☐"
Condition	True	False
Output	Visible text	Hidden text

 

Example 11

Using the IfElse() function together with And() and Not() to set the visibility of a smart field based on the value of two checkbox questions originating from the response form, 'Product A' and 'Product C' must both be checked, and 'Product B' must be unchecked for the text to be visible.

Binding	{{IfElse(And(Form.ProductA, Not(Form.ProductB), Form.ProductC), VisibilityType.Visible, VisibilityType.Hidden))}}
Input	Form.ProductA = "☑" Form.ProductB = "☐" Form.ProductC = "☑"	Form.ProductA = "☑" Form.ProductB = "☑" Form.ProductC = "☑"
Condition	True	False
Output	Visible text	Hidden text

 

Example 12

Using the IfElse() function together with Contains() to display or hide some text based on the value of the 'UserProfile.Office.Name' originating from the user profile.

• If the 'UserProfile.Office.Name' is 'Copenhagen' or 'Berlin', the text should be hidden.
• If the 'UserProfile.Office.Name' is anything else, the text should be shown.

Binding	{{IfElse(Contains("Copenhagen, Berlin", UserProfile.Office.Name), VisibilityType.Hidden, VisibilityType.Visible)}}
Input	UserProfile.Office.Name = "Berlin"	UserProfile.Office.Name = "Copenhagen"	UserProfile.Office.Name = "Eindhoven"
Output	Hidden text	Hidden text	Visible text

 

Example 13

Using the IfElse() function to dynamically insert a text element/slide based on the value of the 'Checkbox' checkbox question (of type Checkbox) originating from the response form.
The value '123456787654321' used in the example is the Asset Id of the text element.

Binding	{{IfElse(Form.Checkbox,"123456787654321","")}}
Input	Form.Checkbox = "☑"	Form.Checkbox = "☐"
Condition	True	False
Output	Text element/slide inserted	Text element/slide not inserted

 

If the text element/slide inserted contains questions in the response form, a dropdown question should be used, as the text element/slide questions will not be displayed when using a checkbox.

 

Example 14

Using the IfElse() function together with Equals() to display the value of the 'Subject' question (of type Text) originating from the response form if the HostSystem value is empty.

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