Dedecms实现tags云标签随机颜色与字体大小方法详解

function getTagStyle()
{
$minFontSize=8; //最小字体大小,可根据需要自行更改
$maxFontSize=18; //最大字体大小,可根据需要自行更改
return 'font-size:'.($minFontSize+lcg_value()*(abs($maxFontSize-$minFontSize))).'px;color:#'.dechex(rand(0,255)).dechex(rand(0,196)).dechex(rand(0,255));
}

{dede:tag row='45' getall='1' sort='hot'}
<a href='[field:link/]' title="[field:tag /]([field:total /])" style="[field:total runphp=yes]@me=getTagStyle();[/field:total]">[field:tag /]</a>
{/dede:tag}
