最近用ThinkPHP3.1版本重写了下自己的轻博客系统,新增加了标签库功能,如果使用过织梦或是74CMS的标签,会对此比较熟悉,标签库源码如下:

<?php

import('TagLib');

class TagLibBlog extends TagLib {



   protected $tags=array(

       'blog_cate'=>array('attr'=>'typeid,reid,model,menu,order,limit,name','close'=>0),

       'blog_blog'=>array('attr'=>'id,typeid,order,limit,name','close'=>0),

       'blog_link'=>array('attr'=>'kind,order,limit,name','close'=>0),

       'blog_sql'=>array('attr'=>'sql,name','close'=>0),

       'blog_comment'=>array('attr'=>'aid,reid,order,limit,name','close'=>0),

       'blog_tag'=>array('attr'=>'order,limit,name','close'=>0),

       'blog_group'=>array('attr'=>'order,limit,name','close'=>0),

   );



   //获取栏目信息

   public function _blog_cate($attr){

       $attr=$this->parseXmlAttr($attr);

       extract($attr);

       $sql='where 1';

       if(isset($typeid)){

           $sql.=" and id=$typeid";

       }

       if(isset($reid)){

           $sql.=" and reid=$reid";

       }

       if(isset($model)){

           $sql.=" and model=$model";

       }

       if(isset($menu)){

           $sql.=" and menu=$menu";

       }

       if(isset($order)){

           $sql.=" order by $order";

       }

       if(isset($limit)){

           $sql.=" limit $limit";

       }

       if(emptyempty($name)){

           $name='list';

       }

       $str=<<<str

       <?php

       ${$name}=M()->query("select id,name,reid from blog_category {$sql}");

       import('@.Class.Tool');

       ${$name}=Tool::formatMultiArray(${$name});

       ?>

str;

       return $str;

   }



   //获取博文列表

   public function _blog_blog($attr){

       $attr=$this->parseXmlAttr($attr);

       extract($attr);

       $sql='where 1';

       if(isset($id)){

           $sql.=" and a.id in ($id)";

       }

       if(isset($typeid)){

           import('@.Class.Tool');

           $categories=M('category')->select();

           $arr=Tool::getChildsId($categories,$typeid);

           $arrStr=implode(",",$arrStr);

           $sql.=" and a.reid in ($typeid)";

       }

       if(isset($order)){

           $sql.=" order by a.$order";

       }

       if(isset($limit)){
