Does Ninox actually store documents or simply link to them?

Yes it does upload the document and images for the cloud version.

If you share a table as HTML, the Image feild is "shared" via http. You can attach some types of documents to the Image field besides image files.

once that is done, I create a trigger on create action that does this:

mainShareURL := "https://share.ninoxdb.de/ReplaceWithYourTableShareURL"

This is the code on my button. The mainShareURL button must be properly populated for it to work:

let response := http("GET", mainShareURL);
let startNum := index(text(response.result), ">" + text(this.Id) + "<");
let Text1 := substr(text(response.result), startNum);
startNum := index(Text1, "a href=");
Text1 := substr(Text1, startNum);
let endNum := index(Text1, "<img");
path := substr(Text1, 9, endNum - 11);
startNum := index(path, "files");
path := substr(path, startNum - 1);
URL := mainShareURL + path;
Text := printAndSaveRecord(this, "layout")

The button basicly gives you the path to the files.

the last line on the button  script is not needed. It was from some other testing.

Text := printAndSaveRecord(this, "layout")

Oh, you have to make sure the view you share has the ID field included.
