When run a query with WP_Query method, I got an object. I understand that I can then do the loop to display stuffs. But, my goal is not to display anything, instead, I want to get some post data by doing something like "foreach...". How can I get an array of post data that I can loop through and get data?

It's no clear what you want. Please explain your main goal a bit better and post your current state of code here. –  rofflox Aug 11 '12 at 8:17

You should read the function reference for WP_Query on the WordPress codex. There you have a lot of examples to look at. If you don't want to loop over the resultset using a while, you could get all posts returned by the query with the WP_Query class method get_posts().

For example

$query = new WP_Query(array('post_type' => 'page'));
$posts = $query->get_posts();

foreach($posts as $post) {
    // Do your stuff, e.g.
    // echo $post->post_name;
}

That helps! Exactly what I need, thanks! –  Jenny Aug 11 '12 at 8:40
    
None of the examples you link to demonstrates how to process posts, though. So it's good that you answered, pity they don't have it in the documentation. Another tip: If you're doing a match on a unique post you can use a function like this with 'posts_per_page'=>1 in args. function wp_queryfirstpost($args) { $q=new WP_Query($args); $pp=$q->get_posts(); $firstpost=false;if ($pp) $firstpost=$pp[0]; wp_reset_postdata(); return $firstpost; } –  Henrik Erlandsson Mar 21 at 9:38
