In Genesis Facebook group a user wants to know how
- 18 posts can be shown on search and category archives
- 6 posts can be shown on the first page of Posts page
with the default number of posts as set in Settings > Reading appearing in all other views incl. the paginated pages of the Posts page.
We can set this up using pre_get_posts filter.
Add the following in child theme’s functions.php:
add_action( 'pre_get_posts', 'sk_query_offset', 1 );
/**
* Change Posts Per Page in various views
*
* @author Sridhar Katakam
* @link https://sridharkatakam.com/display-different-number-posts-different-views-wordpress/
* @param object $query data
*
*/
function sk_query_offset( &$query ) {
// if this is not the main query or on the admin back end, abort.
if ( !$query->is_main_query() || is_admin() ) {
return;
}
// if search or category archive, set 18 posts per page
elseif ( is_search() || is_category() ) {
$query->set( 'posts_per_page', '18' );
}
// if not Posts page, abort. i.e., rest of the code below applies to Posts page.
if ( !$query->is_home() ) {
return;
}
// First, define your desired offset...
$offset = -4; // 10 - 4 = 6 where 10 is the number set at Settings > Reading
// Next, determine how many posts per page you want (we'll use WordPress's settings)
$ppp = get_option( 'posts_per_page' );
// Next, detect and handle pagination...
if ( $query->is_paged ) {
// Manually determine page query offset (offset + current page (minus one) x posts per page)
$page_offset = $offset + ( ( $query->query_vars['paged']-1 ) * $ppp );
// Apply adjust page offset
$query->set( 'offset', $page_offset );
}
else {
// This is the first page. Set a different number for posts per page
$query->set( 'posts_per_page', $offset + $ppp );
}
}
add_filter( 'found_posts', 'sk_adjust_offset_pagination', 1, 2 );
function sk_adjust_offset_pagination( $found_posts, $query ) {
// Define our offset again...
$offset = -4;
// Ensure we're modifying the right query object...
if ( $query->is_home() && is_main_query() ) {
// Reduce WordPress's found_posts count by the offset...
return $found_posts - $offset;
}
return $found_posts;
