Sample input:

Container field

Sample output:

Interactive container field with preview

Function definition: (Copy & paste into FileMaker's Edit Custom Function window)

// Generate a preview. Inserting into a container field by script step just gets us an icon.
// This Base64 Encode/Decode generates the preview.

Let ( [

PDF.Name = GetContainerAttribute ( ContainerField ; "filename" ) ;
PDF.Data = ContainerField

] ;

Base64Decode ( Base64Encode ( PDF.Data ) ; PDF.Name )

)

When inserting a file into a container field via script step, we do not get a preview, and the resulting container is not interactive.

This method generates a preview and gets us an interactive container field.

When inserting a PDF into a container field via script step, without user interaction, FM would only give an icon instead of making the container interactive. $PDF is a path to the PDF on disk that I need: Insert File [ Target: TABLE::Container_Field ; â€œ$PDFâ€ ] Commit Records/Requests [ With dialog: Off ] Set Field [ TABLE::Container_Field ; GeneratePreview ( TABLE::Container_Field ) ]
