我正在尝试构建一个wp\\u查询，到目前为止，我已经使用以下查询获得了所需的结果。

$args = array(
    \'meta_query\' => array(
        \'relation\' => \'OR\',
         array( //check if meta key exists
                \'key\' => \'youtube-1\',
                \'compare\' => \'=\',
             ),
             array( //or not exists 
                \'key\' => \'youtube-1\',
                \'compare\' => \'NOT EXISTS\'
             )
        ),
    \'orderby\' => \'meta_value_num\',
    \'order\' => \'DESC\',
);

The problem:我想检查所有youtube元键，它们是从foreach循环中提取的数组形式。例如array(youtube-1, youtube-2, youtube-3, youtube-4 and so on..)

当然，这些职位将由meta_value_num.

任何小费都将不胜感激。谢谢

$args = array(
          \'numberposts\' => -1,
          \'post_type\' => \'post\',
          \'meta_query\' => array (
            array (
              \'key\' => \'my_key\',
              \'value\' => \'target_value\',
                          \'compare\' => \'IN\'
            )
          ) );      

        $new_query = new WP_Query( $args );
