setCustomVariable if not set

General questions
1

Hi,

as I understand each call to setCustomVariable overwrites the previous setting .

Is it possible to make the value of setCustomVariable persistent or to do setCustomVariableIfNotSet

I’m aware of the scope=visit parameter, however as far as I understand this does not prevent overwriting the existing value.

Seen some example’s pushing functions but I can’t get it to work.


_pag.push { function

if not custom variable {
 setCustomVariable [..];
 storeCustomVariablesInCookie();
}
}

actual goal is to set up simpel A/B testing, later on the page will be some code like


switch CustomVariable
  case 1 : write some css;
  case 2 : write other css;

any other suggestions how to set up A/B testing with piwik are welcome of course
