pre_get_posts 在我看来，您的子主题函数文件是最好的。

add_action( \'pre_get_posts\', \'wpsites_custom_get_posts\' );

function wpsites_custom_get_posts( $query ) {

if( $query->is_main_query() && $query->is_home() ) {

$query->set( \'cat\', \'-182,-184\' );

$query->set( \'posts_per_page\', \'12\' );

$query->set( \'orderby\', \'RAND\' );
    }
}

您将要使用new WP_Query. Here\'s why.

以下是您可以尝试的示例：

$args=array(
    \'posts_per_page\' => -1,
    \'orderby\'   => \'rand\',
    \'category__not_in\' => array(182, 184)
);

$query = new WP_Query($args);

if( $query->have_posts() ) { while ($query->have_posts()) : $query->the_post();

    // Do loop stuff here

endwhile; }

wp_reset_query();
