显示（相关）家长

Question

当产品（和子产品）类别页面和商店页面中的条件标记（是产品类别）同时出现时，我无法应用下面的代码。

希望有人能帮忙。

我的目标：每个产品类别页面（包括家长）

参考代码片段和代码片段

//* Used when the widget is displayed as a dropdown
add_filter('woocommerce_product_categories_widget_dropdown_args', 'appliances', 10, 10);
//* Used when the widget is displayed as a list
add_filter('woocommerce_product_categories_widget_args', 'appliances', 10, 10);
function appliances($cat_args) {
  if (is_product_category(75) || is_product_category($termchildren)) {
    // Create an array that will hold the ids that need to be included
    $include_terms = array();
    // Push the default term that you need to shown 
    array_push($include_terms, 75);
    // Create an array that will hold the ids that need to be included
    $termchildren = get_term_children(75, 'product_cat');
    }
  if (is_product_category(59) || is_product_category($termchildren)) {
    // Create an array that will hold the ids that need to be included
    $include_terms = array();
    // Push the default term that you need to shown 
    array_push($include_terms, 59);
    // Create an array that will hold the ids that need to be included
    $termchildren = get_term_children(59, 'product_cat');
    }
    foreach($termchildren as $child) {
      $term = get_term_by('id', $child, 'product_cat');
      array_push($include_terms, $term - > term_id);
    }
    // Finally pass the array
    $cat_args['include'] = $include_terms;
  }
  return $cat_args;
}

经过几天的反复试验，下面是对我有用的代码片段：

1. 使用多个条件标记
2. 仅显示相关类别(

希望能帮助这里的任何人，并希望有人能改进这个答案。

//* Used when the widget is displayed as an slug (aabc) / term_id (50) lists
add_filter( 'woocommerce_product_categories_widget_args', function ( $cat_args ) {
if ( is_product_category('aabc') || is_product_category('ddef') || is_product_category('gghi') || is_product_category('jjkl') || is_product_category('mmno') || is_product_category('ppqr') || is_product_category('sstu') || is_product_category('vvwx') || is_product_category('yyz')){
        // Create an array that will hold the ids that need to be included
        $include_terms = array();
        // Push the default term that you need to show 
        array_push( $include_terms, 50 );
        // Create an array that will hold the ids that need to be included
        $termchildren = get_term_children( 50, 'product_cat' );
        // Iterate over the terms found and add it to the array which holds the IDs to include
        foreach( $termchildren as $child ) {
            $term = get_term_by( 'id', $child, 'product_cat' );
