Checking if SharePoint Person Field is Blank + Condition if true update / if false update

(0) ShareShare
ReportReport
Posted on by 12

I'm trying to build a flow as follows: 

 

When a new Form response is submitted, get response details and create new item in list1. Using an Odata filter on get items based on matching job number field from list1 to project number field in list 2; filter array to extract item (person) information. Condition checks to see whether item (person) in a SharePoint list to see if the field is blank in list 1. If the person field is blank in list 1, then update list 2 with engineer to "UNASSIGNED" and engineer email to "defaultemail@default". 

 

I've tried using both expressions (empty(outputs('Filter_array)) and (length(outputs('Filter_array)) with inaccurate results. It either always marks as true, or always marks as false regardless of if there is data in the array.

    @emiwil This doesn't look like a Filter Array action.

    This is a Filter Array action:

    creativeopinion_1-1714081937433.png

    However, I don't believe that's the correct action to use for your case. You should use an expression to check and see if the person field is empty. 

     

    While building and testing a flow for MS Forms, it's recommended to use a Manual trigger so you don't need to leave Power Automate to trigger your flow. 

    creativeopinion_5-1714082310011.png

    Add Compose action to store the expression. Rename your actions to keep your flow organized.

    creativeopinion_6-1714082342972.png

    Insert the empty() function.

     

    creativeopinion_3-1714082176249.png

    Click on the dynamic content tab and insert the dynamic content for your person column. The name should match your column name.

     

    creativeopinion_2-1714082161950.png

    Run a test. Review the outputs. The empty() function will return a true value if the column is empty.

    creativeopinion_4-1714082212855.png

     

    The if() function takes three parameters. The first parameter is a condition that returns a boolan value (aka true or false), the second parameter is the value that is returned if the condition is true. The last parameter is the value returned if the condition is false. 

    if([true/false],[true value],[false value])

     

    Compose your expression to suit your requirements. The true/false value will come from the expression created previously. 

     

    Click on the expression to edit it. Add if with an opening parenthesis to the start.

    creativeopinion_7-1714084411339.png

    Press the down arrow key to go to the end of the expression. Add a comma. Tip: Pay attention to the tool tip as it bolds the text of the current parameter you are setting. 

    creativeopinion_8-1714084598715.png

    Insert the dynamic content of the true value or enter static text. If your value is a string of text, ensure you have single quotes around it. 

    creativeopinion_9-1714084672210.png

     

    Add another comma and enter the false value. Click on the dynamic content tab and insert the dynamic content from your form.

    creativeopinion_10-1714084721633.png

     

    Add a closing parenthesis and don't forget to press update.

    creativeopinion_11-1714084747454.png

     

    Run a test.

     

    You can now insert the output of the Compose action into any subsequent actions.

    Hi @creativeopinion  Thank you so much for this advice!  It's still returning a false result if the value is blank. I think it's because there are brackets in the field when there is no person assigned, so it's not registering as "empty". Do you have any advice for how to overcome this roadblock?

    @emiwil as per my original post, can you confirm the output of the Compose action with just the empty() function? This is the first test I demoed.

    @emiwil Are you using a single person column? I just tested it on my end and my Compose action comes back true. 

     

    You could try to use a different expression to see if the value is null. 

     

    equals([dynamic content],null)

    Thank you so much @creativeopinion ! You are a wizard! That expression did the trick and is returning accurate results now. You have no idea how helpful this is. I appreciate your advice in troubleshooting. Your YouTube videos are excellent by the way.
