I have a WP blog with a few pages and posts and several categories. I want to write a loop to retrieve images attached to the posts (not the pages) and only those from a specific category and it's children. The category id is 60.
This is the WP_Query call:
$my_query = new WP_Query( array( 'post_type' => 'attachment', 'cat' => '60', 'post_mime_type' =>'image', 'posts_per_page' => $batch_size, 'nopaging' => false, 'post_status' => 'all', 'post_parent' => null, 'meta_key' => 'my_hash', 'orderby' => 'meta_value' ) );
But I get nothing!
What am I doing wrong?
