在函数中添加以下代码。php

for acf

function get_all_meta($type){
              global $wpdb;
              $result = $wpdb->get_results($wpdb->prepare(
                  "SELECT post_id,meta_key,meta_value FROM wp_posts,wp_postmeta WHERE post_type = %s
                    AND wp_posts.ID = wp_postmeta.post_id", $type
              ), ARRAY_A);
               return $result;
          }

function acf(){
    $options = array();
    $acf = get_all_meta(\'acf\');
    foreach($acf as $key => $value){
      $options[\'post_type\'][$value[\'post_id\']][\'post_id\'] = $value[\'post_id\'];
      $test = substr($value[\'meta_key\'], 0, 6);
      if($test === \'field_\'){
        $post_types = maybe_unserialize( $value[\'meta_value\'] );
        $options[\'post_type\'][$value[\'post_id\']][\'key\'][] = $post_types[\'key\'];
        $options[\'post_type\'][$value[\'post_id\']][\'key\'][] = $post_types[\'name\'];
        $options[\'post_type\'][$value[\'post_id\']][\'key\'][] = $post_types[\'type\'];
      }
      if($value[\'meta_key\'] == \'rule\'){
        $post_types = maybe_unserialize( $value[\'meta_value\'] );

        $options[\'post_type\'][$value[\'post_id\']][\'post_types\'] = $post_types[\'value\'];
      }
    }
    return $options;
  }

这将为您提供acf的post meta key的数组值。

How to use

foreach(acf() as $key => $value){
update_post_meta(76, $value[\'type\'], \'Steve\');
}

For pods

函数pods（）{global$wpdb；//获取pods post type id。

    $result = $wpdb->get_results($wpdb->prepare(
      "SELECT ID,post_title,post_parent FROM wp_posts WHERE post_type = %s", $type
    ), ARRAY_A);

// pods each field for a post type create separate post type so again query to get the field post type result.
    $pods_field_post_type = array();    
    foreach($result as $value){
    $pods_field_post_type = $wpdb->get_results($wpdb->prepare(
    "SELECT ID,post_title,post_name FROM wp_posts WHERE post_type = %s
    AND post_parent = %d
    ", \'_pods_field\',$value["ID"]
    ), ARRAY_A);

    }
$fields = array();
   foreach($pods_field_post_type as key => $value):
     $podsAPI = new PodsAPI();
     $pod = $podsAPI->load_pod( array( \'name\' => \'
  post\' ));
     $fields[] = $pod[\'fields\'][$value[\'post_name\']][\'type\'];
  endforeach;
  }
print_r($fields);

How to use

foreach($fields as $key => $value){
update_post_meta(76, $value, \'Steve\');
}

函数acf（）和pods（）为您提供该post类型的确切元键。如果复制并粘贴代码，则可能无法工作。
