Append Values to Custom Variables (instead of replace) Doable? (1 reply)

Is it possible to modify piwik to append values to custom variables instead of replacing them? That would be GOLDEN! I setup a custom variable called Social Action scope visit, and clicking a social link works and updates the record for the visitor. But as soon as the visitor clicks another social link, the value is replaced. I know that is normal with piwik.

So, basically if a visitor clicked both of these:

onclick: _paq.push(['setCustomVariable',3,'Social Action','Twitter Click','visit'])
onclick: _paq.push(['setCustomVariable',3,'Social Action','Facebook Click','visit'])

It will only show last value...

Social Action = Facebook Click

This would be GOLDEN:

Social Action = Twitter Click, Facebook Click

Really, I would imagine this be a very simple mod. Get current value, append (implode) new value (comma separated) and save.

Can anyone please point me to any information that would help me accomplish this? What file(s) / method(s) would I need to modify? I would be very grateful for any info!

Using 1.12 (just downgraded from 2.0 as it wasn't working :( )
Thank you
