How to show horizontal posts from specific category and add thumbnail…

add a category parameter to the query:
https://codex.www.ads-software.com/Class_Reference/WP_Query

about thumbs:
https://codex.www.ads-software.com/Post_Thumbnails

here is the code https://pastebin.com/zJ01ff0V i read the codex but am not sure where to place this code $query = new WP_Query( ‘cat=4’ );

Thanks

where to place this code $query = new WP_Query( ‘cat=4’ );

nowhere – the link was meant to point to the category parameters you could use in your existing query_posts() code.

example:

$args = array(
   'posts_per_page' => $posts_per_page,
   'paged' => $paged,
   'cat' => 4
);
query_posts($args);

Thanks that worked like a charm…for the thumbnail i need to add this wootheme code above the title …
