How to get all unique categories for posts in loop?

EDIT: Moved $i = 0 outside the loop. That should get you the full list of categories. $get_posts = new WP_Query(); $i = 0; $get_posts->query($args); if($get_posts->have_posts()) { $cats = array(); while($get_posts->have_posts()) { $get_posts->the_post(); $post_categories = wp_get_post_categories( get_the_ID() ); foreach($post_categories as $c){ $cat = get_category( $c ); $cats[$i] = $cat->slug ; $i++; } } //endwhile $result … Read more

WP_Query posts_per_page Only Bringing Back one post

Looks like you might be missing the wp_reset_postdata() in here. The WordPress codex shows you need to have a wp_reset_postdata() after your while loop.

Yes you can pass the variable in category_name. But I think it should be get_the_title() instead of the_title(). $title = get_the_title(); $args = array( ‘category_name’ => $title ); Try this. But remember category_name only accepts category slug, not category name. You can also use following method if your page title/slug are different. And I think … Read more
