PowerApps · Enforce File Type on the Attachment Control

[momureithi]

Hello,

I would like to enforce the attaching of PDF files only, on the attachment control on my form.

Anyone who can help with this?

Thanks,

Mo'

Hi @momureithi ,

Put this on the OnAddFile of the Attachment Control

If(
    Right(
        Last(Self.Attachments).Name,
        3
    ) <> "pdf",
    Notify(
        "You can only attach PDF files",
        NotificationType.Error
    );
    Reset(Self)
)

@WarrenBelz , Can you please suggest the formula to accept .pdf,.xls and .doc files?

[WarrenBelz]

@SumanthDundi7 ,

You just need to add them

<> "pdf" || <> "doc" || <> "xls"

Hi Warren - what would your suggestion be for:

pfd, xls, xlsx, doc, docx, 

So allowing for the 3 & 4 digit file extensions.

@AdamH ,

Simply add them all in

Ok - I thought 

 Last(Self.Attachments).Name,
        3
    ) <> "pdf",

was looking at the last 3 of the file extension, for example i was thinking it would see: pfd, xls, lsx, doc, ocx, instead of pfd, xls, xlsx, doc, docx,
