I have set up a feature class that can store images and documents (BLOB data type for both).
When I load the feature layer in a geoform these fields are not visible - I cannot attach them to the form.
Is there a way to do so?
You will need to enable attachments for the feature class:
Enabling attachments—ArcGIS Help | ArcGIS for Desktop
If you published the feature class as a hosted feature service, you can do this in ArcGIS Online:
Enable attachment to the feature service—GeoPlanner for ArcGIS | ArcGIS
Many thanks for your help, it works now.
I might ask for too much, but is it possible to enable more than one attachment? An image and a document as well?
No doubt you have already found the answer - but yes you can multiple attachments.
I haven't tested how many but certainly 20
