Question

我尝试在父/子类别模板（woocommerce）中显示父和子类别。我使用下面的代码，它只是在父类别中显示子类别。

更新代码：

<?php
            $counter = 0;
            $term = get_queried_object();

            $children = get_terms( $term->taxonomy, array(
                'parent'    => $term->term_id,
                'hide_empty' => false
            ) );

            $categories = [ $term ];

            // If $children is an array just merge the "current" (parent) category with the children
            if ( is_array( $children ) ) {
                $categories = array_merge( $categories, $children );
            }


            foreach( $categories as $subcat ) {
                    echo '<ul><li><a href="' . esc_url(get_term_link($subcat, $subcat->taxonomy)) . '">' . $subcat->name . '</a></li></ul>';
            }
        ?>

在这种情况下，您要查询所有“子项”，在尝试创建包含所有已有数据的数组时，只需构造它。

<?php
            $counter = 0;
            $term = get_queried_object();

            $children = get_terms( $term->taxonomy, array(
                'parent'    => $term->term_id,
                'hide_empty' => false
            ) );

            $categories = [ $term ];

            // If $children is an array just merge the "current" (parent) category with the children
            if ( is_array( $children ) ) {
                $categories = array_merge( $categories, $children );
            }


            foreach( $categories as $subcat ) {
                    echo '<ul><li><a href="' . esc_url(get_term_link($subcat, $subcat->taxonomy)) . '">' . $subcat->name . '</a></li></ul>';
            }
        ?>

如您在上面的示例中看到的那样，添加了一小段代码来代替将两个数组合并为一个数组。

如何在父/子类别模板中同时输出父和子类别
