,织梦会员中心发布文章自动过滤外部外部链接,保留本站站内链接。这个织梦默认后台本身带有这样的功能的,只是会员模块里没有而已。, ,我们可以把功能嫁接到会员模块里去使用,实现自动过滤外部链接,实现教程:
,打开 /member/inc/inc_archives_functions.php 在文件的最下面插入:
,/**, * 删除非站内链接, *, * @access public, * @param string $body 内容, * @param array $allow_urls 允许的超链接, * @return string, */,function Replace_Links( &$body, $allow_urls=array() ),{, $host_rule = join(‘|’, $allow_urls);, $host_rule = preg_replace(“#[nr]#”, ”, $host_rule);, $host_rule = str_replace(‘.’, “\.”, $host_rule);, $host_rule = str_replace(‘/’, “\/”, $host_rule);, $arr = ”;, preg_match_all(“#<a([^>]*)>(.*)</a>#iU”, $body, $arr);, if( is_array($arr[0]) ), {, $rparr = array();, $tgarr = array();, foreach($arr[0] as $i=>$v), {, if( $host_rule != ” && preg_match(‘#’.$host_rule.’#i’, $arr[1][$i]) ), {, continue;, } else {, $rparr[] = $v;, $tgarr[] = $arr[2][$i];, }, }, if( !empty($rparr) ), {, $body = str_replace($rparr, $tgarr, $body);, }, }, $arr = $rparr = $tgarr = ”;, return $body;,}
,继续在这个文件中找到,大概在329行:
,//自动摘要
,在它上面加入:
,//删除非站内链接,$allow_urls = array($_SERVER[‘HTTP_HOST’]);,// 读取允许的超链接设置,if(file_exists(DEDEDATA.”/admin/allowurl.txt”)),{,$allow_urls = array_merge($allow_urls, file(DEDEDATA.”/admin/allowurl.txt”));,},$body = Replace_Links($body, $allow_urls);
