Question

我具有“设备”的自定义帖子类型以及“序列号”的元键。我想查询wp-admin中的序列postmeta字段。

我在https://mydomain/wp-admin/edit.php?post_type=equipment上设置了一个“自定义”搜索页面

所有这些都工作正常，问题是，我希望它默认查询序列/模型后置。我的自定义功能似乎无效。它确实测试正确，因为我正在将$ query数组打印到屏幕上。

add_action( 'pre_get_posts', 'admin_search_meta' );

function admin_search_meta( $query ) {

$type = get_query_var('post_type');
if (  $query->is_main_query() && is_admin() && $type == "equipment") {


        //$query->set( 'posts_per_page', '-1' );

        $meta_query_args = array(
                'relation' => 'AND',
                array(
                    'key'     => 'serial',
                    'value'   => get_query_var('s'),
                    'compare' => 'REGEXP'
                ),

                array(
                    'key'     => 'model',
                    'value'   => get_query_var('s'),
                    'compare' => 'REGEXP'
                )

            );
        $query->set( 'meta_query', $meta_query_args );

print_r($query);

}

}

这是print_r（$ query）;

的输出

在wp-admin中使用pre_get_posts
