How can I exclude one specific post from a WP_Query query? (For example, show all posts apart from a post with the ID 278)
I've tried the post__not_in argument but it just removes all posts..
Any help would be great.
Here is my current query
<?php $temp = $wp_query; $wp_query= null; $wp_query = new WP_Query(array( 'post_type' => 'case-study', 'paged' => $paged, )); while ($wp_query->have_posts()) : $wp_query->the_post(); ?>
