The problem seems pretty straight forward: Once the
save_post action is fired, I would like to append the value of a meta key onto the end of the
post_content if it's not already found within the post itself.
I've attempted making a call to
wp_update_post() from within a function tied to
save_post, but as many of you will immediately object,
do_action('save_post') and as such creates an infinite loop.
What other way (using the API) exists for one to update the content of a post based on said posts custom values once the post has been saved/edited without invoking a nightmarish infinite loop?
