How-to add Google Analytics tracking to Zenphoto

This is the patch I apply on each Zenphoto I install and upgrade. This little hack add Google Analytics tracking for all users except administrators.

Why ? As you can see in ticket #441 in Zenphoto bugtracker, there is no intention of adding support of GA in Zenphoto, even as an optional plugin. Hence my tiny hack. And for the non-admin stuff, I like having unbiased statistics: on low-audience websites, administrators can generate more traffic than legitimate users (if not all…).

Here is the downloadable patch file, and its content:

This patch was generated from a Zenphoto v1.2 and will likely not work with any other version.

Do not forget to update the dummy Google Analytics account ID above (UA-XXXXXX-Y) by yours.

And finally, to apply the patch, invoke the classic patch command:

patch -p0 < ./google-analytics-tracking-for-non-admin-users.patch
