Answer 1

你的循环条件中的操作符错误。将其更改为：

<?php

                              $taxonomyName =get_query_var( 'product_cat' ); // use use get_queried_object()->taxonomy; to get the current taxonomy name
                              $countchildren = count (get_term_children( $term_id, $taxonomyName ));

                     echo '<h3 class="group-products mts mbm  cat-title text-underline">'.'<span class="big">'.'Products Families'.'<span class="cont-post">'.'(' .$countchildren.')'.'</span>'.'</span>'.'</h3>';

                    ?>

Answer 2

你的问题在于循环本身，所以不是：

    for(int i = 0; i = < Tail_amount; i++)

你需要：

    for(int i = 0; i <= Tail_amount; i++)

交换运算符，因为这是检查i是否小于或等于Tail_amount的正确语法。
