通过WordPress的过滤器the_category来自定义输出内容。方法很简单，但是很实用。以下是一个示例代码：

function custom_the_category($thelist, $separator = '', $parents = '') {// 获取当前文章的所有分类$categories = get_the_category();if (empty($categories)) {return $thelist;}$thelist = '';foreach ($categories as $category) {$cat_name = esc_html($category->name);$cat_link = esc_url(get_category_link($category->term_id));// 自定义每个分类的HTML结构$thelist .= '<div class="custom-category-item">';$thelist .= '<a href="' . $cat_link . '" class="custom-category-link">';$thelist .= '<span class="custom-category-name">' . $cat_name . '</span>';$thelist .= '</a>';$thelist .= '</div>';}return $thelist;
}
add_filter('the_category', 'custom_the_category', 10, 3);

然后在模板文件中，你可以像平常一样调用the_category()函数：

<?php the_category(', '); ?>
