我正试图从一个自定义的帖子类型中随机抽取一篇帖子，我给它一个分类法。出于某种原因，它正在发布任何帖子，无论是哪一类。

这是我的帖子类型

if (!function_exists(\'register_recipe_post_type\')):

//Registering Post Type

function register_recipe_post_type() {
    $labels = array(
        \'name\'                => __(\'Recipes\'),

   register_post_type(\'recipe\', $args);

   flush_rewrite_rules();
}
add_action(\'init\', \'register_recipe_post_type\');

endif;

这是我的自定义分类法

这里是我正在执行的查询，它提取任何分类法，而不是我指定的分类法

// WP_Query arguments
$args = array (

\'tax_query\'              => array(
    \'taxonomy\' => \'vodka_type\',
    \'field\' => \'slug\',
    \'terms\' => \'origin\', // <-- This is the tax. it\'s supposed to be
),
);
// The Query
$query = new WP_Query( $args );
if($query->have_posts()) :
  while ($query->have_posts()) : $query->the_post();
   // Do Stuff With The Post
  endwhile;
  wp_reset_query();
endif; 

// tax_query needs to be an Array of an Array
\'tax_query\'  => array(
    array(
      \'taxonomy\' => \'vodka_type\',
      \'field\' => \'slug\',
      \'terms\' => $type,
