Verify if User() exist in the SP list

Hello everybody!

 

I want to verify if current user occur in the SP list. I tried some ideas but without positive results.

 

If(LookUp(List; User().FullName in Person.DisplayName; Person.DisplayName) = User().FullName; Navigate(Screen; Fade); Set(Incorrect;"You are not member!"))

 

Also I tried to use CurrentUser method but it doesn't working also. 

 

Thank a lot for Yours answers!

Hi @shaggy ,

Firstly, you will have a delegation issue with User()>FullName. The workaround is to set a Variable

Set(vUser,User().FullName)

There is also a delegation issue with In - so try this:

If(
   !isBlank(
      LookUp(
         List, 
         vUser = Person.DisplayName
      ),
      Person.DisplayName
   ),
   Navigate(Screen,Fade), 
   Set(Incorrect,"You are not member!")
)

Pardon the commas - semi-colons mean a new command for me.

@shaggy  If(LookUp(List, <FieldName in list>= User().FullName),true,"Error")

@WarrenBelz 

 

It doesn't work, there is error ( red marks)

 

If(!IsBlank(LookUp(List; vUser = Person.DisplayName); Person.DisplayName);Navigate(Screen; Fade); Set(Incorrect;"You are not member!"))

 

= -> incorrect type of argument

Person.DisplayName -> also here is something wrong

Unfortunately is also doesn't work

Hi @shaggy ,

I was trying to give you some guidance on a process using the field names you supplied (which is the bit not working). What I was pointing out is the delegation issues with In and User().FullName. Can you please give me

  • The name of the list containing the user’s name
  • The field name in the list containing the name.

As an example, if the list name is Person and the field name is DisplayName then

If(
   !isBlank(
      LookUp(
         Person, 
         vUser = DisplayName
      ),
      DisplayName
   ),
   Navigate(Screen,Fade), 
   Set(Incorrect,"You are not member!")
)

should work after you set the Variable vUser to User().FullName

 

Please what is the name of your table (Is it SPList) and what is the name of your Column/Field that holds your user names in your database. Being Clear on this will help

@WarrenBelzand @kbilakanti 

 

List name : Members

 

Ther is just one column called "Person" and set as "Person or Group"

If(CountRows(Filter(Members,Person = User().FullName)) > 0, Navigate(Screen, Fade), Notify("You are not member!"))

 

Please change the Screen to your screen name

Hi @shaggy,

Thanks for clarifying that. In my last post I catered for a text field assuming the previous one did not work for this reason.

OK - I do not use this field type myself, however I assume that it is no different from any other complex field type with a table structure.

I will try another approach assuming you have less than 2000 items in Members.

ClearCollect(
   colMembers,
   Members
);   //put it all in a collection

If(
   User().FullName in colMember.Person,
   Navigate(Screen,Fade),
   Set(
      Incorrect,"You are not member"
   ),
)

There are no delegation issues querying a collection, so you can go back to the old operators.
