Contact Form 7 advices to add this code to the Additional Settings field at the bottom of the contact form management page
on_sent_ok: "_gaq.push(['_trackEvent', 'Contact Form', 'Submit']);"
Actually that is a bad idea. Be tracked by Google is not every one’s favourite idea of a free internet, so people block Google Analytics either by any tracker blocker, like Ghostery or Disconnect, by Googles official `opt out extension` or by simple blocking the script in a firewall.
Yes, Internet is the only one place on earth you have to `opt-out` to live quiet and peaceful.
When a user has blocked the Analytics script and visits your contact form, he can’t submit it. It will not submit nor show any error-message. It will do nothing, except show an obscure JS error in the console.
`Uncaught exception: ReferenceError: Undefined variable: _gaq`
To fix this, wrap your code up in a try and catch, so it won’t stop on the error and submitting will not halt:
on_sent_ok: "try{_gaq.push(['_trackEvent', 'Contact Form', 'Submit']);} catch(e){}"
Integrating Contact Form 7 and Google Universal Analytics this way is more robust.
