I would like to get 12 post on the homepage and 16 on the other pages

Hi there,

Can you link us to the homepage and the other pages you are referring to?

Hello Ying

Yes ! In private message you can get the URL
Thank you

1. Go to settings > reading, and set the Blog pages show at most to 16.

2. Add this PHP snippet:

add_action( 'pre_get_posts', 'yh_query_offset', 1 );
function yh_query_offset( &$query ) {
        if ( is_admin() ) {
            return;
        }

	// Before anything else, make sure this is the right query...
	if ( ! ( is_main_query() ) ) {
		return;
	}

        // Don't do anything to Elements.
        if ( 'gp_elements' === $query->get( 'post_type' ) ) {
            return;
        }

	// First, define your desired offset...
	$offset = -4;

	// 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', 'yh_adjust_offset_pagination', 1, 2 );
function yh_adjust_offset_pagination( $found_posts, $query ) {
        if ( is_admin() ) {
            return;
        }

	// Define our offset again...
	$offset = -4;
	//get posts per page from WP settings
	$ppp = get_option( 'posts_per_page' );
	$real_page_numbers =ceil(($found_posts - $ppp - $offset) / $ppp) + 1;

	// Ensure we're modifying the right query object...
	if ( is_main_query() && ! is_paged() ) {
		// Reduce WordPress's found_posts count by the offset...
		return $real_page_numbers * ($ppp + $offset);
	}
	 return $real_page_numbers * $ppp;
	
}

Thank you but It also shows 16 in the right sidebar "Last post" ... and random image :(

The query in the sidebar is the same as the main query of the blog, these are repeated content which I don't think is good for SEO.

Will you consider removing them from the blog?

Noop, the plugin is "Recent Posts Widget With Thumbnails" and I want to keep it, I think It looks good on the website
If my demande is not possible : never mind ... or maybe you have another solution to fix this ?

Thank you for your kind help anyway
MArc

In that case, I would recommend reaching out to the plugin support and asking how to target their loop.

Show them the PHP snippet, they should be able to help!

I'll do that thank's a lot
Marc

No Problem, glad to help :)
