Better way to allowing certain file types to be uploaded

Hi everyone,

I have the following set up, but for some strange reason its hit and miss.

On my attachment control I want to allow only image file types to be uploaded.

I have created a label (LblAttachmentWarning) and its visible property is set to:

If(Not(".img" || ".IMG" || ".png" || ".PNG" || ".gif" || ".GIF" || ".jpg" || ".JPG" in Concat(DataCardValue23.Attachments.Name,Name&",")),true)

and the next buttons visible property on that screen set to:

!LblAttachmentWarning.Visible

This seems to randomly work, sometimes I can upload a .GIF and the next button is visible and I can sometimes upload the same image and the label stays visible, so the next button is invisible, is there a better way of achieving my goal or is there an issue in my code?

Hi @Anonymous ,

Put this on the OnAddFile of the Attachment control

With( { wExt: Lower( Right( Last(Self.Attachments).Name, 3 ) ) }, If( wExt <> "jpg" && wExt <> "png" && wExt <> "gif" && wExt <> "img", Notify( "Only Image files allowed", NotificationType.Error ); Reset(Self) ) )

Hi @WarrenBelz

Tried that while in studio mode and it would not allow me to upload any file types the notification appears regardless of it being an img file type

@Anonymous ,

Sorry - danger of free-typing without testing.

Should be And && not Or ||- fixed on original post now.
