Adam, this is awesome! Just curious if it's possible to tell it to open whatever is in the file attachment field - not a specific file url? This is the closest thing to a solution that I've found anywhere, but need it to just show whatever file is in the file attachment field. Think document library. Any ideas?

    Sherry, there is a way to preview most normal file types if you are willing to set your file attachment field to be viewable without logging in.  The technique is in Kirk Trachy's  Magic Buttons app.

    Here are the steps.  You don't have to understand the code page. Just copy paste.

    Step 1.

    Create a Code page called iframe.html
    <html>
    <head><title></title></head>
    <body>

    <iframe id="kirk" style="height:100%;width:100%;border:none;overflow: scroll;"></iframe>

    <script>

        const urlParams = new URLSearchParams(window.location.search);
        const rid = urlParams.get('rid');
        const tabledbid = urlParams.get('tabledbid');
        const myurlroot = urlParams.get('myurlroot');
        const fileattachmentfid = urlParams.get('fileattachmentfid');
        const src = "https://docs.google.com/gview?url=" + myurlroot + "/up/" + tabledbid + "/a/r" + rid + "/e" + fileattachmentfid + "/v0&embedded=true"; 

    document.getElementById("kirk").src = src

    </script>
    </body>
    </html>
    ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~`
    Step 2
    Create this field called Attachment type.
     
    var text Suffix = Right([Receipt Photo or Attachment],".");

    var text NonPhotoFileType = 
    Case($Suffix,
    "xls", "File",
    "xlsx", "File",
    "pdf", "File",
    "doc", "File",
    "docx", "File",
    "ppt", "File",
    "pptx", "File");


    If(
    Trim([Receipt Photo or Attachment])="","",
    $NonPhotoFileType<>"", $NonPhotoFileType, "Image")

    ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

    Create the URL field type for the form. Type = URL . Set as iframe.  Set  800 by 800 size.

    If([Attachment Type 1]="File",

    URLRoot()&"db/"&AppID()&"?a=dbpage&pagename=iframe.html&rid="&[Record ID#]
    &"&tabledbid="&Dbid()
    &"&myurlroot="&URLRoot()
    &"&fileattachmentfid=9")

    // This field refers to iframe.html that is located in the pages section of this app. You will need to copy that code page into your app.
    // You will also have to copy the code from this button and update it for your button to reflect what your file attachment's field id (fid) is.  This this example the file attachment is 432.  Yours may be different.
    // Also be sure to "Allow open access     Allow access to this file attachment from a Quickbase link without signing in".  Edit the file attachment field properties and check the checkbox. Gviewer needs to be able to see the file in order to render it.
