Get posts from multiple categories with category

3 comments

1. I think you should check out the codex for Wp_query

   example here below will return allpost with category name “staff” and “news”:

   $query = new WP_Query( 'category_name=staff+news' );
   

   Check this page for more information:

2. I think I figured it out.

   $args= array(
       'post_type' => 'post',
       'posts_per_page' => '1',
       'orderby' => 'rand',
       'tax_query' => array(
           'relation' => 'AND',
           array(
               'relation' => 'OR',
               array(
                   'taxonomy' => 'category',
                   'field' => 'slug',
                   'terms' => 'category-1',
               ),
               array(
                   'taxonomy' => 'category',
                   'field' => 'slug',
                   'terms' => 'category-2',
               ),
               array(
                   'taxonomy' => 'category',
                   'field' => 'slug',
                   'terms' => 'category-3',
               ),
               array(
                   'taxonomy' => 'category',
                   'field' => 'slug',
                   'terms' => 'category-4',
               ),
           ),
           array(
               'taxonomy' => 'category',
               'field' => 'slug',
               'terms' => 'category-5',
           ),
       )
   );

3. Sure you can! That’s the whole point of a CMS like WordPress. Start studying up… here is the documentation on the function get_terms().

   And everything else WordPress Documentation.

   Good luck.
