在 wordpress 简码中允许自定义元字段值在简码中有多个值

Allow multiple value in shortcode for custom meta field value in wordpress shortcode

我有一个简码,如果我将 "rank" 的单个值放在简码中,它就可以正常工作。

[coaches_list 类别="dummy" number="3" rank="2"]

但我想在 "rank" 中传递多个值作为 [coaches_list category="dummy" number="3" rank="2", "6".

'rank' 是与 post 关联的数字类型自定义字段。

过去两天我在互联网上搜索了很多,但没有找到任何结果。请让我知道我哪里出错了。

这是我构建的一段简码:

$args = array(
        'number' => '-1',
        'orderby' => 'id',
        'order' => 'desc',
        'category' => '',
        'meta_key'    => '', 
        'rank'  => '', 

    ), $atts )
);

 global $post;


  $html = "";
  $my_query = new WP_Query( array('post_type' => 'post',
       'posts_per_page' => $number, 'orderby' => $orderby, 'order' => $order, 'category' =>$category, 'meta_key' => 'rank', 'meta_value' =>  $rank ));

  if( $my_query->have_posts() ) : while( $my_query->have_posts() ) : $my_query->the_post();

我会选择 [coaches_list category="dummy" number="3" rank="2,6"]

然后你可以创建一个数组 $ranks = explode(',',$rank);

function my_shortcode($atts){
  extract(shortcode_atts( $args = array( 
    'number' => '-1', 
    'orderby' => 'id', 
    'order' => 'desc', 
    'category' => '', 
    'meta_key' => '', 
    'rank' => '', 
  ),$atts)); 

  $ranks = explode(',',$rank); 
  $html = '<ul>';

  $my_posts = get_posts(array(
    'post_type' => 'post',
    'posts_per_page' => $number, 
    'orderby' => $orderby, 
    'order' => $order, 
    'category' =>$category, 
    'meta_query' => array(
        'key'=>'rank',
        'value'=>$ranks,
        'compare'=>'IN'
    )
  ));

  foreach($my_posts as $rankpost){
    $html .= '<li>'.$rankpost->ID.': '.get_the_title($rankpost->ID).' - Rank: '.get_post_meta($rankpost->ID,'rank',true).'</li>';
  }
  $html .= '</ul>';
  return $html;
}

或者您可以创建一个查询,给出所有 post with rank=2 AND/OR rank=6.
