Core hooks for fragment caching
|Reported by:||sivel||Owned by:||sivel|
I have been running fragment caching for some time, but have seen a few negatives with the way it needs to be implemented currently. With fragment caching potentially becoming even more popular after talks given at WordCamps, core hooks to assist in this are going to become more necessary, for several reasons, such as creating some standardization about how it is integrated into the theme.
Since there are no hooks in something like get_sidebar() -> get_template_part() -> locate_template() -> load_template() you have to create your own function calls to use in a theme to render the sidebar.
In my specific case I was using a child theme, and ended up having to copy over a lot of the parent theme files to make the modification.
My goal is to provide some hooks that would allow use of the standard theme functions such as get_sidebar() but give a plugin or similar access to interrupt the process, generate the cache and output the cache.
My first pass is attached as well as a sample mu-plugin that I have wrote to show how you can use the new hooks to perform fragment caching.
