实现教程如下
1、后台-系统-核心设置-关键字替换,选择【是】
2、后台-系统-其他选项-关键词替换次数,填【1】或者【0】
1:表示文档内容里有多个关键词,只让1个是内链
0:表示文档内容里有多个关键词,都是内链
根据自己的需要填
3、打开 /include/arc.archives.class.php 找到,大概在1187行至1241行,整个函数
function ReplaceKeyword($kw,&$body) { ...中间代码省略 }
改为
function ReplaceKeyword($kw,&$body) { global $cfg_replace_num; $search = "/(alt\\s*=\\s*|title\\s*=\\s*|src\\s*=\\s*)[\\"|\\'](.+?)[\\"|\\']/is"; $body = preg_replace_callback($search, array('Archives', '_base64_encode'), $body); $addsql = ''; if(isset($this->Fields['tags']) && !empty($this->Fields['aid'])) { $this->dsql->SetQuery("SELECT tid FROM `#@__taglist` WHERE aid = '{$this->Fields['aid']}' "); $this->dsql->Execute(); $ids = ''; while($row = $this->dsql->GetArray()) { $ids .= ( $ids=='' ? $row['tid'] : ','.$row['tid'] ); } if($ids != '') { $addsql = " WHERE id IN($ids) "; } if($addsql=='') return $body; } $query = "SELECT * FROM `#@__tagindex` $addsql ORDER BY addtime DESC"; $this->dsql->SetQuery($query); $this->dsql->Execute(); $linkdatas = array(); while($row = $this->dsql->GetArray()) { $row['keyword'] = $row['tag']; $row['rpurl'] = $cfg_cmsurl."/tags.php?/".urlencode($row['tag'])."/"; $linkdatas[] = $row; } if($linkdatas) { $word = $replacement = array(); foreach($linkdatas as $v) { $word1[] = '/(?!(<a.*?))' . preg_quote($v['keyword'], '/') . '(?!.*<\\/a>)/s'; $word2[] = $v['keyword']; $replacement[] = '<a href="'.$v['rpurl'].'" target="_blank">'.$v['keyword'].'</a>'; } if($cfg_replace_num) { $body = preg_replace($word1, $replacement, $body, $cfg_replace_num); } else { $body = str_replace($word2, $replacement, $body); } } $body = preg_replace_callback($search, array('Archives', '_base64_decode'), $body); return $body; } function _base64_encode($matches) { return $matches[1]."\\"".base64_encode($matches[2])."\\""; } function _base64_decode($matches) { return $matches[1]."\\"".base64_decode($matches[2])."\\""; }
4、完成
