Question

我想只显示第一级子分类，下面是我的代码，它只是不起作用，任何人都可以告诉我的代码有什么问题？非常感谢。

<?php

$term_id = 31;
$taxonomy_name = 'kosher_category';

$args = array('child_of' => $term_id, 'parent' => $term_id);
$termchildren = get_terms($taxonomy_name, $args );

echo '<ul>';
foreach ( $termchildren as $child ) {
    $term = get_term_by( 'id', $child, $taxonomy_name );
    echo '<li><a href="#">' . $term->name . '</a></li>';
}
echo '</ul>';
?>

Answer 1

添加hide_empty。

<?php
    $term_id        = 31;
    $taxonomy_name  = 'kosher_category';
    $args           = array(
        'child_of'      => $term_id,
        'parent'        => $term_id,
        'hide_empty'    => false    // ADDED
    );
    $termchildren   = get_terms($taxonomy_name, $args );

    echo '<ul>';
    foreach($termchildren AS $child) {
        $term = get_term_by('id', $child, $taxonomy_name);
        echo '<li><a href="#">' . $term->name . '</a></li>';
    }
    echo '</ul>';
?>
