Find Current User in SharePoint Online List

Hi,

Having some trouble achieving something at the moment; I've found a few very similar threads but nothing seems to work my side/hit exactly what I'm after.

I want to check, on load, whether the current user is a member of a list and depending on that result assign them a role.

I have a list called 'Admin' which is a simple one-column list containing a ~10 users; the datatype is Person/Group.

Currently I have the below in the OnStart section of my Form.

Set(currentUser, User())

A previous iteration also included UpdateContext({currentUser: User()}) but I can't see what, if any impact that is having on the logic.

I then have a Label with the text value of:

If(LookUp(Admin, currentUser.Email in User.Email),"Y","N")

I have also tried currentUser in User etc and also exposed the values in a gallery... If I apply the logic to the gallery it filters to show me the correct result but this doesn't help me in setting the value of a variable.

At this stage I just want to prove yes or no, is this user in this list but it returns blank regardless. Am I missing something very obvious here?

The next step would be to check that if the person is in the list assign them role X, if they're not, role Y.

Hi @Anonymous,

Do you want to check if the current user is within your Admin SP list?

Is the User a Person type column which does not enable "Allow multiple selections" option within your SP list?

Based on the formula that you provided, I think there is something wrong with it. The first argument of the If function is required to provide a Boolean value, but the result your LookUp formula returned is a Record value.

I have made a test on my side, please take a try with the following workaround:

Set the OnVisible property of the first screen of my app to following:

Set(currentUser, User())

Set the Text property of the Label control to following:

If(!IsBlank(LookUp('20190122_case12', currentUser.Email in User.Email)), "Y", "N")

On your side, you should type the following:

If(
!IsBlank(LookUp(Admin, currentUser.Email in User.Email)),
"Y",
"N"
)

Above solution may cause a Delegation warning issue, in order to get rid of this issue, please take a try with the following workaround:

Set the OnVisible property of the first screen of your app to following:

ClearCollect(RecordsCollection, Admin)

Set the Text property of the Label control to following:

If(
!IsBlank(LookUp(RecordsCollection, currentUser.Email in User.Email)),
"Y",
"N"
)

Best regards,

@v-xida-msft Thank you!

I knew it would be something minor; I was assuming that because I expected a true result from the LookUp, this would be passing a boolean but makes sense that some clarification is needed.

Much appreciated!
