using if statements in interface

I'm not sure why it would be doing that - can you confirm what data type your ri!WorkingHours is? If the value was somehow technically "greater than 8" (like perhaps in the back-end storing a value of 8.001 for example) then it would fail the condition. To troubleshoot, maybe try wrapping "ri!workingHours" in the "value" parameter of a!match() in "tointeger()", and see if that changes anything.

Additionally, the truly correct way of using a!match would be that you only invoke ri!workingHours once, then refer to it as fv!value within the "whenTrue" parameter, when needed. The difference may appear cosmetic, though this means that if you format the value parameter (such as using "tointeger()"), then further references to the value will remain consistent.

yes I did.

This works fine for me. Did you populate ri!WorkingHours correctly?

a!richTextDisplayField(
labelPosition: "COLLAPSED",
value: {
a!richTextItem(
a!match(
value: ri!WorkingHours,
equals: 8,
then: "Working Hours are complete",
whenTrue: and(ri!WorkingHours > 0, 8 > ri!WorkingHours),
then: "Working hours are not complete",
default: "insert working hours correctly please"
)
)
}
),

It is working fine for me. You must have misconfigured something. Can you add your code block for more understanding?

Did you take a look at Ujjwal's answer? I think it is a better approach.

Thanks, it's working now, but I'm wondering should I use three conditions every time I want use if statement?

can't I use two only?

RE: using if statements in interface

Amaan Shekh — Tue, 04 Oct 2022 10:51:59 GMT

its because the third if only have two parameters in it

if(
            ri!WorkingHours < 0,
            "insert working hours correctly please"
            )

we can remove this or can pass on more parameter as

if(
            ri!WorkingHours < 0,
            "insert working hours correctly please",
            "working hours passed limit"
          )

, you can choose according to your use case

I missed the third parameter in the last if. You can add an empty list there. I have updated the same code

Amaan Shekh — Tue, 04 Oct 2022 10:47:57 GMT

try this

a!richTextDisplayField(
  value: {
    a!richTextItem(
      if(
        ri!WorkingHours = "8",
        "Working hours are complete",
        if(
          and(8 > ri!WorkingHours, ri!WorkingHours > 0),
          "Working hours are not complete",
          "insert working hours correctly please"
    
        )
      )
    )
  }
)

Thanks for your help, but when I tried the code I got this: Could not display interface. Please check definition and inputs. Interface Definition: Expression evaluation error at function 'if' [line 64]: Invalid number of parameters, function 'if' a minimum of 3 parameters (condition,true,false), passed 2.

Using the amazing match function.

a!richTextDisplayField(
  value: {
    a!richTextItem(
      a!match(
        value: ri!WorkingHours,
        equals: 8,
        then: "Working Hours are complete",
        whenTrue: and(ri!WorkingHours > 0, 8 > ri!WorkingHours),
        then: "Working hours are not complete",
        default: "insert working hours correctly please"
      )
    )
  }
)

Multiple conditions in Appian can be configured using or() & and() functions.

a!richTextDisplayField(
  value: {
    a!richTextItem(
      if(
        ri!WorkingHours = "8",
        "Working hours are complete",
        if(
          and(8 > ri!WorkingHours, ri!WorkingHours > 0),
          "Working hours are not complete",
          if(
            ri!WorkingHours < 0,
            "insert working hours correctly please",
            {}
          )
        )
      )
    )
  }
)
