我网站上的每个帖子都可以被评为“好”、“好”、“坏”。这些值存储在自定义字段中。我现在需要显示最大值为“好”的前10个帖子，而不应该显示值为“好”或“坏”的帖子。

我目前通过以下代码执行此操作

<?php
$orig_post = $post;
global $post;
$args=array(
\'post__not_in\' => array(get_the_ID()),
\'posts_per_page\'=>10, // Number of related posts to display.
\'meta_key\'=>\'good\',
\'orderby\'=>\'meta_value_num\',
\'caller_get_posts\'=>1
);

$my_query = new wp_query( $args );

while( $my_query->have_posts() ) {
$my_query->the_post();

//code for filtering posts based on max good 

$good_val = get_post_meta(get_the_ID(),\'good\',true);
$ok_val = get_post_meta(get_the_ID(),\'ok\',true);
$bad_val = get_post_meta(get_the_ID(),\'bad\',true);

$maxValue=max($good_val,$ok_val,$bad_val);


if ($maxValue == $good_val)
{the_title();}}

$post = $orig_post;
wp_reset_query();
?>

上面的代码在查询后过滤帖子，这有时会导致不正确的结果。不管怎样，我们都可以在中进行筛选（即比较3个值）wp_query 它本身

$args=array(
  \'post__not_in\' => array(get_the_ID()),
  \'posts_per_page\' => 10, // Number of related posts to display.
  \'meta_query\' = array(
    array(
      \'key\' => \'my_gob_rating\',
      \'value\' => 10, // whatever the cutoff is between \'ok\' and \'good\'
      \'compare\' => \'>=\',
    )
  ),
  \'ignore_sticky_posts\' => true
);
