RiPro v2主题 – 用代码实现彩色标签云

美化说明：
修改替换默认标签云背景颜色改为定义好的颜色,让标签云更加的好看!
代码部署:
首先利用宝塔或则FTP打开主题目录/inc/options下的admin-options.php文件把下面代码放在38行左右（给主题添加个开关按钮）

array(
            'id' => 'is_tags_cloud',
            'type' => 'switcher',
            'title' => '彩色标签云',
            'label' => '启用后标签云中的标签的颜色为随机颜色',
            'default' => false,
        ),

最后在主题根目录下打开functions.php将以下代码放在最后即可

// 标签云彩色代码

if (_cao('is_tags_cloud')) {
  function colorCloud($text) { 
    $text = preg_replace_callback('|<a (.+?)>|i', 'colorCloudCallback', $text);
    return $text; 
  } 

  function colorCloudCallback($matches) { 
    $text = $matches[1]; 
    $colors = array('48d1cc','a26ff9','fb7da9','6a6da9','19b5fe','ff5e5c','ffbb50','1ac756','7fb80e','6950a1'); 
    $color = $colors[dechex(rand(0,count($colors)-1))];
    $pattern = '/style=("|\')(.*?)\1/i'; 
    $text = preg_replace($pattern, "style=\"display: inline-block; *display: inline; *zoom: 1; color: #fff; padding: 1px 2px; margin: 0 2px 2px 0; background-color: #{$color}; border-radius: 2px; -webkit-transition: background-color .4s linear; -moz-transition: background-color .4s linear; transition: background-color .4s linear;\"", $text); 
    return "<a $text>"; 
  } 

  add_filter('wp_tag_cloud', 'colorCloud', 1);
}
