如何过滤WP_Query

Question

我正在使用WP_Query

$the_query = new WP_Query( array( 'post_type' => 'testimonials', 'showposts' => -1 ) );，它会检索所有帖子类型为＆＃34;推荐书＆＃34;，

的帖子

所以

我需要根据metakey =＆＃34; rate＆＃34;的帖子过滤它们。和metavalue＆lt; = 4

  array( 
     'post_type' => 'testimonials', 
     'showposts' => -1,
     'meta_key' => 'rate',
     'meta_value' => 4,
     'meta_compare' => '<='
   ) 
);
