显示从页面的自定义字段（WP）中选择的自定义帖子类型分类

问题描述：

I've created a custom post type and taxonomy for it. I want admin to be able to chose a taxonomy they want to show on the page when creating a new one (page). I've created a custom page template, and there is a conditional custom field that shows available taxonomies, when that template is selected. Used custom post type UI and advanced custom fields plugins for that.

<?php
    // this one gets taxonomy custom field
    $taxo = get_field('top_to_show');
    // and from here on, it outputs the custom post type
    $args = array(
      'post_type' => 'top_item',
      'post_status' => 'publish',
      'tops' => $taxo
    );
    $lineblocks = new WP_Query( $args );
    if( $lineblocks->have_posts() ) {
      while( $lineblocks->have_posts() ) {
        $lineblocks->the_post();
        ?>

<div>Custom post type layout html</div>

<?php
      }
    }
    else {
      echo '';
    }
 wp_reset_query(); ?>

Now, when I select "Term ID" for taxonomy custom field for the page, it doesn't show anything at all. And when I select "Term Object", it shows all posts from all taxonomies, and not the specifically selected one.

How do I make it show that specifically chosen taxonomy posts?

我为它创建了一个自定义的帖子类型和分类。我希望管理员能够在创建新的（页面）时选择他们想要在页面上显示的分类。我已经创建了一个自定义页面模板，并且在选择该模板时，有一个条件自定义字段显示可用的分类。使用自定义帖子类型UI和高级自定义字段插件。 p>

 ＆lt;？php 
 //这个获得分类自定义字段
 $ taxo = get_field（'top_to_show'）; 
 //从这里开始，它 输出自定义帖子类型
 $ args = array（
'post_type'=＆gt;'top_item'，
'post_status'=＆gt;'publish'，
'tops'=＆gt; $ taxo 
）;  
 $ lineblocks = new WP_Query（$ args）; 
 if（$ lineblocks-＆gt; have_posts（））{
 while（$ lineblocks-＆gt; have_posts（））{
 $ lineblocks-＆gt; the_post（）  ; 
？＆gt; 
 
＆lt; div＆gt;自定义帖子类型布局html＆lt; / div＆gt; 
 
＆lt;？php 
} 
} 
其他{
 echo''; 
} 
  wp_reset_query（）;  ？＆gt; 
  code>  pre> 
 
 现在，当我为页面的分类自定义字段选择“术语ID”时，它根本不显示任何内容。 当我选择“术语对象”时，它会显示所有分类中的所有帖子，而不是具体选择的帖子。   p> 
 
 
如何让它显示特定选择的分类标准帖？ p>

答

That method of retrieving posts by taxonomy, with the tax parameter, is deprecated: https://codex.wordpress.org/Class_Reference/WP_Query#Taxonomy_Parameters

You should use tax_query instead. Assuming 'tops' is the name of the taxonomy, and your custom field returns the Term ID only:

$args = array(
    'post_type' => 'top_item',
    'post_status' => 'publish',
    'tax_query' => array(
        array(
            'taxonomy' => 'tops',
            'field'    => 'term_id',
            'terms'    => $taxo,

        ),
    ),
);
