感觉Wordpress自带标签云不太美观，而上次使用Simple Tags插件虽然方便，但却在IE9中显示异常，只好弃用。今天决定用直接修改代码方式来修改标签显示。

查了下，并不困难，只需要改函数wp_tag_cloud的几个参数即可。

位于”/public_html/wp-includes/category-template.php”,，Wordpress原始代码为：

function wp_tag_cloud( $args = ” ) {
    $defaults = array(
        ‘smallest’ => 8, ‘largest’ => 22, ‘unit’ => ‘pt’, ‘number’ => 45,
        ‘format’ => ‘flat’, ‘separator’ => “\n”, ‘orderby’ => ‘name’, ‘order’ => ‘ASC’,
        ‘exclude’ => ”, ‘include’ => ”, ‘link’ => ‘view’, ‘taxonomy’ => ‘post_tag’, ‘echo’ => true
    );

修改如下：

function wp_tag_cloud( $args = ” ) {
    $defaults = array(
        ‘smallest’ => 6, ‘largest’ => 26, ‘unit’ => ‘pt’, ‘number’ => 66,
        ‘format’ => ‘flat’, ‘separator’ => “\n”, ‘orderby’ => ‘count’, ‘order’ => ‘DESC’,
        ‘exclude’ => ”, ‘include’ => ”, ‘link’ => ‘view’, ‘taxonomy’ => ‘post_tag’, ‘echo’ => true
    );

smallest最小的标签字号，largest最大的标签字号。
‘separator’ => “\n”标签用空格分隔

orderby排序依据：name名称，count数量
order顺序：ASC升序、递增 DESC降序、递减

wordpress安装插件Simple Tags.学到两个缩写 Asc,ascending order升序 Desc,descending order降序

这个递增与递减有些歧义，顺序指从开始到结束的顺序，但从开始到结束是从上到下还是从下到上，即上面还是下面是开始？目前的国际主流看法应该是视上面为开始,但这与人的生活经验与心理相反。

★Wordpress.org官网介绍函数wp_tag_cloud()

The wp_tag_cloud() function displays a list of tags in what is called a ‘tag cloud’, where the size of each tag is determined by how many times that particular tag has been assigned to posts.

函数wp_tag_cloud() 显示一个被叫做标签云的标签列表，在那里各个标签的大小由特定标签曾经被分配给帖子的数目来决定。

Default Usage默认用法

    ‘number’                    => 45,  标签数目
    ‘format’                    => ‘flat’,
    ‘separator’                 => \\”\n\\“,标签分隔符
    ‘orderby’                   => ‘name’, 标签以什么排序
    ‘order’                     => ‘ASC’, 顺序
