WOOF_Collection of MEOW_Post
A collection of posts selected in the UI. Note that since this method affects the main loop, and can therefore be used prior to the main WordPress loop, the return value may end up being ignored.
Retrieves the posts selected in the field UI, while also affecting the main WordPress query loop.
Either a string or array of query arguments as accepted by WordPress’ get_posts method.
Note that this method will ALWAYS override the post__in argument, since technically it infers the IDs of the selected posts first, and uses post__in to return them.
