WordPress自带标签云美化三种教程

在主题的function.php文件中,找个合适位置加入以下任何一段代码:

第一种

//修改WordPress自带标签云小工具的显示参数
add_filter( 'widget_tag_cloud_args', 'theme_tag_cloud_args' );
function theme_tag_cloud_args( $args ){
	$newargs = array(
		'smallest'    => 14,     //最小字号
		'largest'     => 20,     //最大字号
		'unit'        => 'px',   //字号单位,可以是pt、px、em或%
		'number'      => 80,     //显示个数
		'format'      => 'array',//列表格式,可以是flat、list或array
		'separator'   => "\n",   //分隔每一项的分隔符
		'orderby'     => 'name', //排序字段,可以是name或count
		'order'       => 'RAND', //升序ASC或降序DESC,RAND随机
		'exclude'     => null,   //结果中排除某些标签
		'include'     => null,   //结果中只包含这些标签
		'link'        => 'view'  //taxonomy链接,view或edit
		'taxonomy'    => 'post_tag', //调用哪些分类法作为标签云
	);
	$return = array_merge( $args, $newargs);
	return $return;
}

第二种

// 实现彩色标签云  
function colorCloud($text) {   
        $text = preg_replace_callback('||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 "";   
    }   
    add_filter('wp_tag_cloud', 'colorCloud', 1);

第三种

//WordPress圆角彩色背景标签云
function colorCloud($text) {  
$text = preg_replace_callback('||i', 'colorCloudCallback', $text);  
return $text;  
}  
function colorCloudCallback($matches) {  
$text = $matches[1];  
$colors = array('F99','C9C','F96','6CC','6C9','37A7FF','B0D686','E6CC6E');  
$color=$colors[dechex(rand(0,7))]; 
$pattern = '/style=(\'|\")(.*)(\'|\")/i';  
$text = preg_replace($pattern, "style=\"display: inline-block; *display: inline; *zoom: 1; color: #fff; padding: 1px 5px; margin: 0 5px 5px 0; background-color: #{$color}; border-radius: 3px; -webkit-transition: background-color .4s linear; -moz-transition: background-color .4s linear; transition: background-color .4s linear;\"", $text);  
$pattern = '/style=(\'|\")(.*)(\'|\")/i';  
return "";  
}  
add_filter('wp_tag_cloud', 'colorCloud', 1);
