Limit posts on a WP_Query and in WooCommerce product query

问题

In Woocommerce, I need to limit post with a wp_query.

I know how to limit post in wp_query

For example if this page id is 20, I am running the query:

function wpcodex_filter_main_search_post_limits( $limit, $query ) {

    if ( get_the_ID()==20 ) {
        return 'LIMIT 0, 12';
    }

    return $limit;
}


add_filter( 'post_limits', 'wpcodex_filter_main_search_post_limits', 10, 2 );

But I need to set the limt as 25 to 35.

How to do this?

Even if I am placing return 'LIMIT 25, 35'; it is still showing first 35 products, not the posts between 25 to 35.

That query is like: LIMIT 10 OFFSET 15

Please help me.

The answer is… taratata!!!! :

function wpcodex_filter_main_search_post_limits( $limit, $query ) {
    if ( get_the_ID()==20 ) {
        return 'LIMIT 25, 10'; 
    }
    return $limit;
}
add_filter( 'post_limits', 'wpcodex_filter_main_search_post_limits', 10, 2 );

Because in 'LIMIT 25, 10';, here 25 is the offset and 10 the number of posts to display. So that way it will display 10 products beginning with the product 26…
