效果如  http://www.sanshu.cn/a/38.html 内链是很多 站长都重视的一个SEO的步骤，不光可以引导蜘蛛去抓取，也能在别人采集你网站内容的时候带上你的链接。 本修改支持分类或话题或分类加话题的内链。大家可以自己选择。建议大家别用分类加话题 因为处理效率比前面2者的要慢 一倍。   好了开始上代码了: 首先需要增加一个model 类。 取名为:innerlink.php 放在网站根目录的/model下

if (!defined('IN_ANWSION'))

class innerlink_class extends AWS_MODEL
{
	public function get_category_topic_list($type=1)
	{
		
		$result_cache_key = 'get_category_tag_list'.$type;
	//	AWS_APP::cache()->delete($result_cache_key);
		if ($result = AWS_APP::cache()->get($result_cache_key)){
			return $result;
		}
		switch($type){
			case 1:
				$sql = "SELECT `id` ,`title`,'c' as t  FROM   ".get_table('category');
				break;
			case 2:
				$sql = " SELECT `topic_id` id  ,`topic_title` title,'t' as t  FROM ".get_table('topic');
				break;
			default:
				$sql = "SELECT `id` ,`title`,'c'  as t   FROM ".get_table('category')." union SELECT `topic_id` id  ,`topic_title` title,'t'  as t   FROM ".get_table('topic');	
		}
		
		if ($result = $this->query_all($sql))
		{
			$filter = array('href','ref','ef','f');
			$i=0;
			foreach($result as $r) {
				if(in_array($r['title'],$filter))continue;
				$resulta[$r['title']]['id'] = $r['id'];
				$resulta[$r['title']]['title'] = $r['title'];
				$resulta[$r['title']]['t'] = $r['t'];
			}
			AWS_APP::cache()->set($result_cache_key, $resulta, get_setting('cache_level_high'));
			return $resulta;
		}else{
			return null;
		}
		
	}
}

第二步 修改 app/article/main.php  搜索代码  $article_info['user_info'] = $this->model('account')->get_user_info_by_uid($article_info['uid'], true);  在 这个下面写

$content = $article_info['message'];
			$res = $this->model('innerlink')->get_category_topic_list(1);
			//print_r($res);
			foreach($res  AS $r) {
				$id = $r['id'];
				$title = $r['title'];
				 if($r['t']=='c'){
				 	$content = str_replace($title,"$title",$content);
				 }else{
				 	$content = str_replace($title,"$title",$content);
				 }
			}
			
			$article_info['message'] = $content;

然后就好啦。 ps:只考虑到了功能实现，代码写的不算太好，加上自己又是半吊子的php程序员，大家见谅哈。
