本篇文章编号[1602388444],关键词是dedecms,富文本,内容是关于织梦cms富文本内容中屏蔽标签实例代码的相关知识,小编觉得还有用处,在这里分享给大家做个参考吧。
文章的body字段屏蔽a标签和iframe标签
{dede:field.body runphp="yes"} $str=@me; @me=''; $str1=''; $str1 = preg_replace( "@<iframe(.*?)</iframe>@is", "", $str ); $str1 = preg_replace("/<a[^>]*>(.*?)</a>/is", "$1", $str1); @me=$str1; {/dede:field.body}
以下是过滤其他标签的正则表达式
$str=preg_replace("/s+/", " ", $str); //过滤多余回车 $str=preg_replace("/<[ ]+/si","<",$str); //过滤<__("<"号后面带空格) $str=preg_replace("/<!–.*?–>/si","",$str); //注释 $str=preg_replace("/<(!.*?)>/si","",$str); //过滤DOCTYPE $str=preg_replace("/<(/?html.*?)>/si","",$str); //过滤html标签 $str=preg_replace("/<(/?br.*?)>/si","",$str); //过滤br标签 $str=preg_replace("/<(/?head.*?)>/si","",$str); //过滤head标签 $str=preg_replace("/<(/?meta.*?)>/si","",$str); //过滤meta标签 $str=preg_replace("/<(/?body.*?)>/si","",$str); //过滤body标签 $str=preg_replace("/<(/?link.*?)>/si","",$str); //过滤link标签 $str=preg_replace("/<(/?form.*?)>/si","",$str); //过滤form标签 $str=preg_replace("/cookie/si","COOKIE",$str); //过滤COOKIE标签 $str=preg_replace("/<(applet.*?)>(.*?)<(/applet.*?)>/si","",$str); //过滤applet标签 $str=preg_replace("/<(/?applet.*?)>/si","",$str); //过滤applet标签 $str=preg_replace("/<(style.*?)>(.*?)<(/style.*?)>/si","",$str); //过滤style标签 $str=preg_replace("/<(/?style.*?)>/si","",$str); //过滤style标签 $str=preg_replace("/<(title.*?)>(.*?)<(/title.*?)>/si","",$str); //过滤title标签 $str=preg_replace("/<(/?title.*?)>/si","",$str); //过滤title标签 $str=preg_replace("/<(object.*?)>(.*?)<(/object.*?)>/si","",$str); //过滤object标签 $str=preg_replace("/<(/?objec.*?)>/si","",$str); //过滤object标签 $str=preg_replace("/<(noframes.*?)>(.*?)<(/noframes.*?)>/si","",$str); //过滤noframes标签 $str=preg_replace("/<(/?noframes.*?)>/si","",$str); //过滤noframes标签 $str=preg_replace("/<(i?frame.*?)>(.*?)<(/i?frame.*?)>/si","",$str); //过滤frame标签 $str=preg_replace("/<(/?i?frame.*?)>/si","",$str); //过滤frame标签 $str=preg_replace("/<(script.*?)>(.*?)<(/script.*?)>/si","",$str); //过滤script标签 $str=preg_replace("/<(/?script.*?)>/si","",$str); //过滤script标签 $str=preg_replace("/javascript/si","Javascript",$str); //过滤script标签 $str=preg_replace("/vbscript/si","Vbscript",$str); //过滤script标签 $str=preg_replace("/on([a-z]+)s*=/si","On1=",$str); //过滤script标签 $str=preg_replace("/&#/si","&#",$str); //过滤script标签, $str = preg_replace( "@<script(.*?)</script>@is", "", $str ); //过滤script代码 $str = preg_replace( "@<iframe(.*?)</iframe>@is", "", $str ); $str = preg_replace( "@<style(.*?)</style>@is", "", $str ); $str = preg_replace( "@<(.*?)>@is", "", $str );
