I'm trying to track the same user with JS and PHP. AFAIK I must set the piwik visitor id on the php side, so piwik knows it is the same user. I am trying to do it with this:
The only problem is to set the right $visitor_id. First, I thought I can get it by JS like this:
And then send the visitor_id to the server. But the visitor_id I get by this is always a different one from the one getting logged in the sql table log_visits in column idvisitor and therefore in the visitor log I get two different users.
I looked at the cookies that are sent to the piwik instance and my php site, too. There is always a cookie like the following:
the <VISITOR_ID> is the same one I get by this.getVisitorId() in javascript. So this again is not the one I need.
How can I track the same user by JS and PHP? Is this possible? Can I get the visitor_id used by piwik in some way or is there another solution?
$_p = new PiwikTracker( $id, $piwik_url ); $_p->setTokenAuth( $piwik_token ); $_p->setIp( $_SERVER['REMOTE_ADDR'] ); $_p->setVisitorId( $visitor_id );
