如何在ACF中保存添加的acf_add_local_field？

Question

因此，我在自定义帖子类型（产品）中生成了一个Repeater字段，但是当我尝试保存一些数据并且页面刷新时，它不会保存。

在acf forum中有一个代码，您可以在其中保存中继器字段值，如下所示：

   // save a repeater field value
   $field_key = "field_12345678";
   $value = array(
   array(
     "sub_field_1"  => "Foo",
     "sub_field_2"  => "Bar"
    )
 );
 update_field( $field_key, $value, $post_id );

但是我不确定在我的情况下将$value字段拉到哪里。

这是我的代码：

function wpt_add_product_metaboxes() {
global $post;
$unique_terms = array(); 
$postID              =   $post->ID;
$have_terms          =   get_the_terms($postID, 'product_attributes');

if($have_terms):
    $parent_terms  = wp_get_post_terms( $postID,'product_attributes', array( 'parent' => 0, 'orderby' => 'id', 'order' => 'DESC', 'hide_empty' => false ) );    
    #print("<pre>".print_r($parent_terms,true)."</pre>");
    $ctr = 0;
    foreach ($parent_terms as $p_term):
         $custom_taxnomies_child = wp_get_post_terms($postID, 'product_attributes', array( 'parent' => 66, 'orderby' => 'slug', 'hide_empty' => false ));
          foreach($custom_taxnomies_child as $cterm){
            if( ! in_array( $cterm->term_id, $unique_terms ) ){

                array_push( $unique_terms, $cterm->term_id );
                $ctr++;
                acf_add_local_field( array (
                    'key'               => 'field_tab_size_'.$ctr,
                    'label'             => $cterm->name,
                    'name'              => 'store_sizes_'.$ctr,
                    'type'              => 'tab',
