Question

(Please excuse the confusing formatting in my original post.)

On a form, is it possible to have a field that is not directly entered by the user, but rather calculated?
Given a form definition that contains MyField:

MyField

label

1

%MYFIELD%

Whatever

Now, in the doc that contains the form definition, if I do a

• Set MYFIELD = abc

...when I save the form, MyField displays a value of abc.%br% However, if I look at the raw data, what is actually stored is:
%META:FIELD{name="MyField" title="MyField" value="%MYFIELD%"}%
...that is to say, that Twiki saves the formula (the variable to inherit from) and not the actual value.

So the topic containing the form looks nice when viewed, but if I include it, from a different topic, in a formatted search, a $formfield(MyField) renders as %MYFIELD%, whereas what I want to show is abc. Is there some way of doing this?

Answer

Hm, I don't have an answer, but a kind of workaround. If you use the

%CALC{$SET(myfield,Some Value)}%

construct instead of

   * Set MYFIELD = Some Value

within the topic with the form, containing the label

| MyField | label | 1 | %CALC{$GET(myfield)}% | Whatever |  |

you get the actual value Some Value of the 'variable' myfield when using $formfield(MyField) in a formatted search which result contains that topic with the form.

Or maybe AttachContentPlugin does what you really need, because IIRC the work-around above can't work in combination with (Set) variable settings.
