How to send category name from Wordpress to Google Analytics Content Groups (universal tracking code) - universal-analytics

Question

I want to enable content grouping in Google Analytics by submitting the category of my posts from within the tracking code.
A solution for GA's async version of the tracking code would look like this:
var _gaq = _gaq || [];
_gaq.push(['_setAccount', 'UA-XXXXXX-X']);
<?php
if (is_single()){
echo “_gaq.push(['_setPageGroup', 1, '".get_the_author()."']);\n”;
$category = get_the_category();
if ($category && !empty($category[0]->cat_name)){
echo “_gaq.push([‘_setPageGroup’, 2, ‘”.$category[0]->cat_name.”‘]);\n”;
}
}
?>
_gaq.push(['_trackPageview']);
How can I set up the same functionality using GA's universal tracking code?
Thanks!
Best regards,
Alex

Answer 1

Classic GA syntax:
_gaq.push(['_setPageGroup', '<Index Number>', '<Group Name>']);
UA syntax:
ga('set', 'contentGroup<Index Number>', '<Group Name>');
So in your case it should/would/could be this:
<?php
if (is_single()){
echo "ga('set', contentGroup1, '".get_the_author()."');\n";
$category = get_the_category();
if ($category && !empty($category[0]->cat_name)){
echo "ga('set', contentGroup2, '".$category[0]->cat_name."');\n”;
}
}
?>
