【转载】simple tags 彩色标签云

原文：http://paviorsoft.cn/?p=89

imple tags 除了能够将标签云带颜色的显示出来外 我实在是看不出来它有什么出众的地方

让simple tags显示出彩色效果

1，打开wordpress/wp-content/plugins/simple-tags/2.7/simple-tags.client.php

2，将 function getColorByScale 替换成如下内容

function getColorByScale($scale_color, $min_color, $max_color) {
		$scale_color = $scale_color / 100;
 
		$minr = hexdec(substr($min_color, 1, 2));
		$ming = hexdec(substr($min_color, 3, 2));
		$minb = hexdec(substr($min_color, 5, 2));
 
		$maxr = hexdec(substr($max_color, 1, 2));
		$maxg = hexdec(substr($max_color, 3, 2));
		$maxb = hexdec(substr($max_color, 5, 2));
 
		$r = dechex(intval((($maxr - $minr) * $scale_color) + $minr));
		$g = dechex(intval((($maxg - $ming) * $scale_color) + $ming));
		$b = dechex(intval((($maxb - $minb) * $scale_color) + $minb));
 
		if (strlen($r) == 1) $r = '0'.$r;
		if (strlen($g) == 1) $g = '0'.$g;
		if (strlen($b) == 1) $b = '0'.$b;
 
		$r = dechex(rand(0,255));
		$g = dechex(rand(0,196));
		$b = dechex(rand(0,255));
 
		return '#'.$r.$g.$b;
	}
