Hi Nicola,
It would help to have an idea of the larger issue you're trying to solve
with this multi-frame layout, because there might be a simpler way to
accomplish it. I'm also a bit confused as to whether you're talking
about text or graphic frames. (You wrote "graphic" in the subject but
in the message you said, "I have a template that has several variable
text frames".) Anyway, I'm assuming you mean text frames.
That said, yes, it's possible, but not all in one rule. You're still
going to need four rules, one for each frame. But the logic to
determine how many fields contain a value can be put in a common
function in your JavaScript Globals, so the logic for each rule
shouldn't be too complicated.
For instance, you can have some functions like this in your JavaScript
Globals:
function NumNonEmptyFields()
{
var count = 0;
for (var i = 0; i < arguments.length; i++)
{
try
{
if (Field(arguments[i]))
count++;
}
catch (e)
{
Print(e);
}
}
return count;
}
function MyNonEmptyFields()
{
// Use your own field names here...
return NumNonEmptyFields("Home", "Fax", "Cell", "Office");
}
function MyOutput()
{
// Whatever you want the output to be....
return "here's the output";
// Maybe return a Formatted Text Resource?
//return Resource("MyResource");
}
The rule for frame "A" would look something like this:
if (MyNonEmptyFields() == 4)
return MyOutput();
//else
return "";
And the rule for frame "B" would look something like this
if (MyNonEmptyFields() == 3)
return MyOutput();
//else
return "";
And so on. This can be generalized further as well, by making a
function that takes the number (1, 2, 3, or 4) as a parameter:
function OutputForNumFields(numFields)
{
if (numFields == MyNonEmptyFields())
return MyOutput();
//else
return "";
}
In which case the rule for frame "A" would just be:
return OutputForNumFields(4);
And so on.
Of course, I have no idea what the actual text should be if you're
"using" the frame. That's why I suggested you might want to use a
Formatted Text Resource in the comment, since you can format it just
like you were in the Text Editor for the frame itself, using the
Suppress if Empty (or Suppress if Containing Empty Variables) feature to
only show lines for the non-empty fields.
If you're using graphic frames, then it's just a matter of doing
something like this:
if (MyNonEmptyFields() == 4)
return Resource("MyResource");
//else
return NullResource();
Actually, that same syntax would work for a text rule, if you're
returning a text resource.
