织梦当前文档内容自动关联tag标签做内链

效果

实现教程

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
}

整个修改为:

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) {
			$word0[] = "/<a[^>]*>{$v['keyword']}<\/a>/is";
			$word1[] = '/'.$v['keyword'].'/is';
			$word2[] = $v['keyword'];
			$replacement[] = '<a href="'.$v['rpurl'].'" target="_blank">'.$v['keyword'].'</a>';
		}
		if($cfg_replace_num) {
			$body = preg_replace($word0, $word2, $body, $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])."\"";
}

 

如图

4、完成,动态的直接看效果,静态的记得重新生成文档看效果

注意:这个TAGE链接地址是动态的,效果如下

https://www.xiangyangcity.com/tags.php?/襄阳城/

如果你的如果你的TAG链接是这种的

https://www.xiangyangcity.com/tags/襄阳城/

那你就得把上面代码里面的?删除掉。如下面的红色部分

$row['rpurl'] = $cfg_cmsurl."/tags.php?/".urlencode($row['tag'])."/";
