你可以在WP_Query ，然后使用get_attached_media 查找找到的每个帖子的媒体。你可以在那里进行更具体的查询，这取决于你！

// WP_Query arguments
$args = array(
    \'category_name\'          => \'name_of_your_category\',
);

// The Query
$query = new WP_Query( $args );

// The Loop
if ( $query->have_posts() ) {
    while ( $query->have_posts() ) {
        $query->the_post();
        // Adds all the media attached to each post found in the query
        // This is just an example of how you could use it!
        array_push( $your_array, get_attached_media( \'image\', get_the_ID() ) );
    }
} else {
    // no posts found
}

// Restore original Post Data
wp_reset_postdata();
