I want to query for posts with a certain meta value. I would use the WP_Query but when in a loop (correct me if i am wrong.. I am learning wordpress; is it only when in loop? is the the_post() that sets the globals?), it changes the global $post.

Is it possible to loop without setting up the global values? I just want to fetch some stuff in the posts, i don't want to use the_content, the_title, etc.. just raw rows of arrays?

If I want to query WP_Query with meta fields conditions and expect and want only post, how do I get it? Do I still need to loop?

The query itself doesn't change globals, however you are correct that the_post() does.

The most contained way to just retrieve posts (as array of results) is using get_posts() function, which is wrapper around WP_Query and takes same arguments.

  • yup i am actually using get_posts() which is just executing query() of Wp_Query. ok so if i don't use the_post() or setup_postdata, there's no need for me to use wp_reset_query or wp_reset_postdata right? as globals are untouched? btw: i am using your R Debug class which helped me a lot debugging and understanding some hooks in WP. it's great! will integrate it in my own custom framework for all my plugins development! – yeahman Apr 21 '14 at 18:43
  • sidenote: i am reading that I should use wp_reset_postdata() instead of wp_reset_query() (unless i am using query_posts() which is not recommended) – yeahman Apr 21 '14 at 18:54

    @yeahman correct, unless you use anything that changes globals you do not need to reset afterwards. Also see wordpress.stackexchange.com/a/1755/847 – Rarst Apr 21 '14 at 19:00
  • thx for your help and explanations! I am starting to get more and more familiar to WP :) – yeahman Apr 21 '14 at 19:06
  • and you recommend using a new instance of Wp_Query vs using the global $wp_query? – yeahman Apr 21 '14 at 19:09
