在查看器中插入HTMLInside链接

我有一个自定义导航助行器，它（理论上）从自定义分类法的最新帖子中提取特征图像，并在wp_list_categories.

问题是我需要在链接中的类别名称上方显示图像。我似乎不知道该怎么做。

这是我的定制助行器：

class CategoryThumbnailWalker extends Walker_Category {
    function start_el(&$output, $category, $depth, $args) {
        parent::start_el(&$output, $category, $depth, $args);
        $posts = get_posts(array(
            "child_of"         => $category->term_id, // may need to be disabled; we\'ll see
            "post_type"        => "projects",
            "project-category" => $category->slug,
        ));
        if ($posts) {
            foreach ($posts as $post) {
                if (has_post_thumbnail($post->ID)) {
                    $output .= get_the_post_thumbnail($post->ID, "gallery-small");

                } else {
                    $output .= "<img alt=\\"No image available\\" src=\\"" . get_template_directory_uri() . "/img/no-image.jpg\\" />";
                }
                break;
            }
        } else {
            $output .= "<img alt=\\"No image available\\" src=\\"" . get_template_directory_uri() . "/img/no-image.jpg\\" />";
        }
    }
}

这是我的wp_list_categories:

$category = $wp_query->get_queried_object_id();
wp_list_categories(array(
    "child_of"         => $category,
    "depth"            => 1,
    "hide_empty"       => false,
    "hierarchical"     => 1,
    "orderby"          => "name",
    "pad_counts"       => 0,
    "post_type"        => "projects",
    "show_count"       => 0,
    "show_option_none" => "",
    "taxonomy"         => "project-category",
    "title_li"         => "",
    "walker"           => new CategoryThumbnailWalker()
));

以下是it的全部输出：

    <a href="http://christopherconsultants.myweblinx.net/project-category/education/" title="View all posts filed under Education">
        Education

</li>

add_filter( \'list_cats\', \'wpse_149898_list_cats\', 99, 2 ); wp_list_categories(array( "child_of" => get_queried_object_id(), "depth" => 1, "hide_empty" => false, "hierarchical" => 1, "orderby" => "name", "pad_counts" => 0, "post_type" => "projects", "show_count" => 0, "show_option_none" => "", "taxonomy" => "project-category", "title_li" => "", )); remove_filter( \'list_cats\', \'wpse_149898_list_cats\', 99, 2 );

从WP_LIST_CATEGORIES中删除‘Category’一词

我有以下代码：wp_list_categories();它输出我的所有类别，但是，它使它们成为列表元素的子元素，称为CATEGORIES.所以，我得到了一个无序的列表，如下所示：CATEGORIES * FASHION * DAILY FASHION CANDY * TRENDS * BEAUTY * ACCESSORIES * CELEBRITIES * LIFESTYLE 但是，我只需要：* FASHION * DAILY FA
