If you mean "How do I add these hidden fields to my form?", then you do the following:

1.  Write a simple helper function like so:

private void AddHiddenField(string name, string value)
        {
            HtmlInputHidden htmlHidden = new HtmlInputHidden();
            htmlHidden.ID = name;
            htmlHidden.Name = name;
            htmlHidden.Value = value;
            Page.Form.Controls.Add(htmlHidden);
        }

2.  Add your name/value pair like so...

AddHiddenField("cmd", "_cart");
AddHiddenField("upload", "1");
AddHiddenField("business", _settings.PayPalID);
...Etc

If I've misunderstood your question please let me know.
