1.修改/htdocs/wp-content/themes/mini下的functions.php 文件, 新增以下内容

注意:替换 mini 为当前使用的主题名

/* 彩色标签 */

function colorCloud($text) {

    $text = preg_replace_callback(‘|<a (.+?)>|i’,‘colorCloudCallback’, $text);

    return $text;

}

function colorCloudCallback($matches) {

    $text = $matches[1];

    $color = dechex(rand(0,16777215));

    $pattern = ‘/style=(\’|\”)(.*)(\’|\”)/i’;

    $text = preg_replace($pattern, “style=\”color:#{$color};$2;\”“, $text);

    return “<a $text>”;

}

add_filter(‘wp_tag_cloud’, ‘colorCloud’, 1);

2.需要准备的2个文件

colorful_tags.js

<<colorful_tags.js>>

colorful_tags.css

<<colorful_tags.css>>

3.将这两个文件上传到对应的两个目录下

/htdocs/wp-content/themes/mini/js

/htdocs/wp-content/themes/mini/css

4.修改/htdocs/wp-content/themes/mini 下的header.php文件

在</head>标签前添加以下2行

<link href=“/wp-content/themes/mini/css/colorful_tags.css” rel=“stylesheet” type=“text/css”/>

<script src=‘/wp-content/themes/mini/js/colorful_tags.js’ type=“text/javascript”></script>

注意是在</head>标签之前添加

5.最终效果如下图:

 

下面是js文件与css文件
