Would like to disable the user from being able to attach files that are not either, ".doc, .pdf, .xlsx". Trying to upload an ".xlsx" file type.

I have tried the code below found in an old post, where it checks to see if the extensions are in the name.

ForAll(Self.Attachments,
If(
    Not(
        Or(
            EndsWith(Name, ".docx"),
            EndsWith(Name, ".doc"),
            EndsWith(Name, ".pdf"),
            EndsWith(Name, ".xlsx") 
        )
    ),
    Notify("Only .docx, .doc, .pdf, or .xlsx file types are allowed", NotificationType.Error);
    Reset(Self)
    Collect(colAttachments, value)
)
)

Also tried the code below by saving all the attachments into a collection and then trying to remove them from the collection but it deletes all the items in the collection. Printed the name in a data table and the DisplayName does contain the extension.

ClearCollect(colAttachments, Self.Attachments);
RemoveIf(colAttachments, Not(".pdf" in DisplayName) Or Not(".xlsx" in DisplayName))

Hi! Your last formula gives wrong result because of Or. You need to use And instead.

ClearCollect(colAttachments, Self.Attachments);

RemoveIf(colAttachments, Not(".pdf" in Name) And Not(".xlsx" in Name))

Let me know if this helps.

This is what I use in the 'OnAddFile' property of my attachment control. I only want .xlsx files uploaded, so this works for me. You could add more with an Or statement.

If(

Right(

Last(Self.Attachments).Name,

4

) <> "xlsx",

Notify(

"You can only attach .xlsx files",

NotificationType.Error

);

Reset(Self)

)
