我目前正在尝试向Tag Cloud小部件中的链接添加样式，我可以看到它的用途wp_tag_cloud() 输出云本身。wp\\u tag\\u cloud（）中的参数没有包含我想要的类名，因为设置title属性的样式效率不高，也不允许有太大的增长。例如：

.widget .tagcloud a[title~="1"]{
    color: red;
  }
  .widget .tagcloud a[title~="2"]{
    color: yellow;
  }
  .widget .tagcloud a[title~="9999"]{
    color: purple;
  }

我找到了wp_generate_tag_cloud_data 过滤器，看起来是我想要的，但我必须错过一些东西，因为它没有任何效果。以下是我目前掌握的情况：

add_filter( \'wp_generate_tag_cloud_data\', \'my_tag_cloud_data\', 10, 1 );

function my_tag_cloud_data($tags_data){

foreach ( $tags as $key => $tag ) {
    $tag_id = isset( $tag->id ) ? $tag->id : $key;
    $tag_class= \'tag-link-\' . $tag_id;

    $count = $counts[ $key ];
    $real_count = $real_counts[ $key ];

    if ($real_count > 20){
        $tag_class= \'tag-link-\' . $tag_id . \' x-large\';
    } elseif ($real_count > 15){
        $tag_class= \'tag-link-\' . $tag_id . \' large\';
    } elseif ($real_count > 7){
        $tag_class= \'tag-link-\' . $tag_id . \' medium\';
    } elseif ($real_count > 1){
        $tag_class= \'tag-link-\' . $tag_id . \' small\';
    } else {
        $tag_class= \'tag-link-\' . $tag_id . \'x-small \';
    }

    if ( $translate_nooped_plural ) {
        $title = sprintf( translate_nooped_plural( $translate_nooped_plural, $real_count ), number_format_i18n( $real_count ) );
    } else {
        $title = call_user_func( $args[\'topic_count_text_callback\'], $real_count, $tag, $args );
    }

    $tags_data[] = array(
        \'id\'         => $tag_id,
        \'url\'        => \'#\' != $tag->link ? $tag->link : \'#\',
        \'name\'       => $tag->name,
        \'title\'      => $title,
        \'slug\'       => $tag->slug,
        \'real_count\' => $real_count,
        \'class\'      => $tag_class,
        \'font_size\'  => $args[\'smallest\'] + ( $count - $min_count ) * $font_step,
    );
}

return $tags_data;

}

我尝试过使用优先级并将其包装到绑定到init挂钩的函数中，但没有效果。如果有人能告诉我我做错了什么，我将不胜感激。

add_filter( \'wp_generate_tag_cloud_data\', \'my_tag_cloud_data\', 10, 1 );

function my_tag_cloud_data( $tags_data ) {

    foreach ( $tags_data as $key => $tag ) {

        // get tag count
        $count = $tag [ \'real_count\' ];

        // adjust the class based on the size
        if ( $count > 20 ) {
            $tags_data [ $key ] [ \'class\' ] .= \' tag x-large\';
        } elseif ( $count > 15 ) {
            $tags_data [ $key ] [ \'class\' ] .= \' tag large\';
        } elseif ( $count > 7 ) {
            $tags_data [ $key ] [ \'class\' ] .= \' tag medium\';
        } elseif ( $count > 1 ) {
            $tags_data [ $key ] [ \'class\' ] .= \' tag small\';
        } else {
            $tags_data [ $key ] [ \'class\' ] .= \' tag x-small \';
        }
    }

    // return adjusted data
    return $tags_data;
}

<style>
    .tag.x-large {
        color: red;
    }
    .tag.large {
        color: green;
    }
    .tag.medium {
        color: blue;
    }
    .tag.small {
        color: yellow;
    }
    .tag.x-small {
        color: orange;
    }
</style>
