Wordpress仅显示附加了实践的实践类别

Question

我有一个问题，我的功能是用于wordpress的下拉菜单。它只显示附加了实践的实践类别。如果我删除最后一个forloop，它会显示所有的练习类别，反之亦然。我是一个大的php新手。谢谢。

function lr_get_practice_select_data() {
    $practiceCategories = get_terms(array(
        'taxonomy' => 'practice_category',
        'orderby' => 'name'
    ));
    $out = array();
    foreach ($practiceCategories as $category) {
        $out[] = array(
            'value' => 'category_' .$category->term_id,
            'class' => 'category',
            'name'  => $category->name
        );
        $practicesInCategory = lr_get_practices_by_category($category->term_id);
        foreach ($practicesInCategory as $practice) {
            $out[] = array(
                'value' => $practice->ID,
                'class' => 'practice',
                'name'  => $practice->post_title
            );
        }
    }
    return $out;
}

Answer 1

尝试将'hide_empty' => false添加到您的查询中：

$practiceCategories = get_terms(array(
     'taxonomy' => 'practice_category',
     'orderby' => 'name',
     'hide_empty' => false
));
