Great question. I am looking for this answer too.
Yeah. I want to do the same thing.
Here is what I did…
Went to line 90 of nav-menu-template.php:
$item_output .= '<a'. $attributes .'>';
and modified it to add what I wanted. In this case I needed to add a Google Analytics onclick event to enable cross domain tracking:
onclick="_gaq.push([\'_link\', this.href]); return false;"
The final product is:
$item_output .= '<a'. $attributes .' onclick="_gaq.push([\'_link\', this.href]); return false;" >';
Thanks for the info. very helpful. I’m trying to do the same thing with my Google analytics to track across multiple domains.
I added the code as described above, but how do I know if it’s working? When I hove over the the menu item, it still shows the basic URL and when I click on it, nothing different seems to happen.
Also does using this.href replicate putting the URL back into the the code the way that $attributes does?
To see what’s going on in your cookies in Firefox go to:
Tools > Options > Privacy > Show Cookies
From there you can see if the google _utma _utmb and _utmz values are set. If they are set across domains you know your links are working properly.
I don’t know about this.href vs $attributes
Thanks. I checked around and found some other sources using the this.href in the code. But one thing additional you have is backslashes around the ‘_link’. Is that intentional for wordpress? According to the google references, there are no backslashes in their code. I’m not sure if that will make a difference in how this works.
<a href="http://store.firstfairway.com/golf-clubs-c5.aspx" onclick="_gaq.push(['_link', this.href]); return false;">CLUBS</a>
\’_link\’ versus ‘_link’?
Nevermind. I just figured it out. the backslash is an escape in php so it will literally invoke the single quote.
Thanks @alreadysetup for the code tweak !
But do somebody know another way without changing WP core code ? (this could be unsustainable on WP updates…
palbertus…I’m still looking for a better solution too. I actually have this code added in the nav-menu-template.php as described above, but it doesn’t work.
They way I can tell is that if I click a link in the body of one of my wordpress pages that has the proper onclick syntax added to the hyperlink, I can see the utma, utmb, and utmz values getting passed to the new domain I’m linking too.
But if I click on a link from the wordpress menu, those values are not getting passed. I’ve checked the code I updated in nav-menu-template.php multiple times and it’s correct as posted here, but doesn’t seem to function for me.
I’m going to check with a developer. Ideally this would be best handled as plug in. Seems like an easy update though.
Let me know if you have any success with it, maybe I’m doing something wrong.
