Setting blog for unlimited vertical scroll through all posts. How? [closed]

Question

How can one set blog for unlimited vertical scroll through all posts?

Answer 1

If you want to load the posts as you scroll, you can use the infinite scroll plugin.

If you want all posts pages to load all posts on initial page load, you can go to the Settings > Reading page in admin and enter -1 in the Blog pages show at most field.

If you want to load all posts on a particular page on initial page load on a particular type of posts page, you can use the pre_get_posts action to modify the query just for that page. For example, on the home page:

function wpa85665_all_posts_on_home( $query ) {
    if ( $query->is_home() && $query->is_main_query() )
        $query->set( 'posts_per_page', -1 );
}
add_action( 'pre_get_posts', 'wpa85665_all_posts_on_home' );

See the other Conditional Tags to limit the modification to other types of pages.
