Check if Date selector field is blank in MS Flow formula/expression

part of an email step, we are creating an HTML table, where certain rows are hidden using css.

 

So our expression formula (in the body of the Outlook - Send an email from a Shared Mailbox step looks like this:

 

if(
    And(
        Or(
            equals(triggerBody()['DD_Artwork']['Value'], 'Bargain New Store')
            , equals(triggerBody()['DD_Artwork']['Value'], 'Home & Fashion')
            ,equals(triggerBody()['DD_Artwork']['Value'], 'Home Store'))
        , @empty(triggerBody()?['StoreOpeningDate']))
    ,'tr.StoreOpenDate {display:visible}', 'tr.StoreOpenDate {display:none}')

this part, checking the Date Selector field StoreOpeningDate is not working:

 

, @empty(triggerBody()?['StoreOpeningDate']))

we have also tried:

 

, Not IsBlank(triggerBody()?['StoreOpeningDate']))

but we always get the error message The expression is invalid:

so what's the right way to do this please?

Re: Check if Date selector field is blank in MS Flow formula/expression

Hi @livingstonep,

 

Do you want to return “visible” when DD_Artwork equals Bargain new store/Home & Fashion/Home Store and Store Opening date is not empty, if not, return None?

It seems that there is a @ in the function you are using, please remove it and try again. I have made the following test and it just works fine.

The flow is triggered by SharePoint When an item is created or modified, then send an email. In the email body, use the following code to return results:

 

if(

    And(

        Or(

            equals(triggerBody()?['Title'], 'test1')

            , equals(triggerBody()?['Title'], 'test2')

            ,equals(triggerBody()?['Title'], 'test3'))

        , Not(empty(triggerBody()?['StartDate'])))

,'tr.StoreOpenDate {display:visible}', 'tr.StoreOpenDate {display:none}')

Besides, there is no IsBlank function in WDL functions that can be used in Microsoft flow, please check more available functions at here:

Re: Check if Date selector field is blank in MS Flow formula/expression

Hi 

In my scenario,

 

I am writing code for print form option.

Step1: I wrote a HTML code  for my application

Step2: I used this code on MS FLow 

  • first i'm calling powerapps
  • Prase JSON
  • Comple(HTML Code with parse JSON values added)
  • respond to powerapps
  • Creating an html file

Step3: after creating the flow. I was calling flow from powerapps

step4: Now i was able to get data into the html with flow

 

On my powerapps, based on dropdown select all the other feilds will populate, I'm unable to hide feilds based on dropdown selected value on HTMl.

is there any way to hide labels based on selected value on HTML
