如何将WordPress自定义分类法归档链接设置为/%category%/%taxonomy%

1. 修正自定义分类法注册代码 #

调整register_taxonomy的参数，确保分类法配置适配后续重写规则：

register_taxonomy(
    'season',
    'post',
    array(
        'public'       => true,
        'hierarchical' => true,
        'labels'       => array(
            'name' => '季',
        ),
        'rewrite'      => array(
            'slug'         => 'season',
            'with_front'   => false,
            'hierarchical' => true,
        ),
        'query_var'    => 'season',
    )
);

2. 添加自定义重写规则 #

让WordPress优先识别/%category%/%season%格式的URL，并映射到season分类法查询：

function custom_season_rewrite_rules() {
    add_rewrite_rule(
        '^([^/]+)/([^/]+)/?$',
        'index.php?category_name=$matches[1]&season=$matches[2]',
        'top'
    );
}
add_action('init', 'custom_season_rewrite_rules');

3. 自动生成目标格式的归档链接 #

过滤term_link，让season分类的归档链接自动生成为/%category%/%season%结构：

function custom_season_term_link($termlink, $term, $taxonomy) {
    if ($taxonomy === 'season') {
        // 获取该季关联的第一篇文章，提取所属分类（若一个季对应多个分类，需调整逻辑）
        $posts = get_posts(array(
            'numberposts' => 1,
            'post_type'   => 'post',
            'tax_query'   => array(
                array(
                    'taxonomy' => 'season',
                    'field'    => 'term_id',
                    'terms'    => $term->term_id,
                )
            )
        ));
        
        if (!empty($posts)) {
            $category = get_the_category($posts[0]->ID);
            if (!empty($category)) {
                $cat_slug = $category[0]->slug;
                $termlink = home_url('/' . $cat_slug . '/' . $term->slug . '/');
            }
        }
    }
    return $termlink;
}
add_filter('term_link', 'custom_season_term_link', 10, 3);

4. 强制加载指定模板 #

避免WordPress优先匹配分类规则而加载category.php，强制在season查询时使用taxonomy-season.php：

function custom_season_template($template) {
    if (is_tax('season') || (isset($_GET['season']) && !empty($_GET['season']))) {
        $new_template = locate_template(array('taxonomy-season.php'));
        if (!empty($new_template)) {
            return $new_template;
        }
    }
    return $template;
}
add_filter('template_include', 'custom_season_template');

关键操作 #

修改代码后，务必进入WordPress后台「设置-固定链接」页面，点击「保存更改」刷新重写规则，否则新规则不会生效。
