[wp-hackers] Filters on get_posts()

[Casey Bisson]

John,

I think your approach here is good. That is, there's no reason a filter has to be blindly activated as WP is instantiated, and the globally applied.

Filters such as you describe should look at the context of the query and optionally activate themselves. Then immediately deactivate once their work is done. The parse-query and pre-get-posts actions are good places to apply filters, then simply remove_filter() as you run them. 

If you're running multiple loops, you can do yourself a favor by calling do_action('my_loop_name') just before calling wp_query(), as that will give you an opportunity to set whatever filters you want based on that specific loop/query.
