WordPress如何使用多个meta_query和meta_key

$args = array(
    'post_type' => 'post',
    'meta_query' => array(
        'relation' => 'AND',
        array(
            'key' => 'publish_date',
            'value' => '2023-01-01',
            'compare' => '>=',
            'type' => 'DATE',
        ),
        array(
            'key' => 'article_type',
            'value' => 'tutorial',
            'compare' => '=',
        ),
        array(
            'key' => 'author',
            'value' => 'John Doe',
            'compare' => '=',
        ),
    ),
);

$the_query = new WP_Query($args);

if ($the_query->have_posts()) {
    while ($the_query->have_posts()) {
        $the_query->the_post();
        // 显示文章内容
    }
    wp_reset_postdata();
} else {
    echo '没有找到符合条件的文章';
}

$posts = get_posts(array(
    'post_type' => 'post',
    'numberposts' => -1,
    'fields' => 'ids',
));

foreach ($posts as $post_id) {
    $meta_values = get_post_meta($post_id, 'publish_date', true);
    var_dump($meta_values);
}
