ThinkPHP分组下自定义标签库实例

import('TagLib');
class TagLibBlog extends TagLib {
}

class TagLibBlog extends TagLib {
   protected $tags =array(
       'mynav'=>array('attr'=>'limit,order','close'=>1)
       / .jb51.
       这里$tags数组内,每个单元也就是每一行代表一个标签,例如{dede:article},我们这里也定义了一个mynav,
       然后每一行标签的键名就是标签名,键值是一个数组,该数组包含两个单元,第一个就是attr，就是标签中得属性,以逗号分隔,
       如num,typeid等等,close的值如果是0的话就是非闭合标签,1的话就是闭合，意思是要以</mynav>来结尾
       /
   );
}

public function _mynav($attr,$content){
   $attr=$this->parseXmlAttr($attr);
  
   import('@.Class.Tool');
   $categories=M('category')->limit($attr['limit'])->order($attr['order'])->select();
   $categories=Tool::formatMultiArray($categories);
  
   $str='';
   for($i=0;$i<count($categories);$i++){
       $model=array(
           '/[field.id]/',
           '/[field.name]/'
       );
       $replace=array(
           $categories[$i]['id'],
           $categories[$i]['name']
       );
       $str.=preg_replace($model,$replace,$content);
   }
  
   return $str;
}

//加载标签库

标签库完整源码如下
<?php
import('TagLib');
class TagLibBlog extends TagLib {
  
   protected $tags=array(
       'mynav'=>array('attr'=>'limit,order','close'=>1)
   );
  
   public function _mynav($attr,$content){
       $attr=$this->parseXmlAttr($attr);
      
       import('@.Class.Tool');
       $categories=M('category')->limit($attr['limit'])->order($attr['order'])->select();
       $categories=Tool::formatMultiArray($categories);
      
       $str='';
       for($i=0;$i<count($categories);$i++){
           $model=array(
               '/[field.id]/',
               '/[field.name]/'
           );
           $replace=array(
               $categories[$i]['id'],
               $categories[$i]['name']
           );
           $str.=preg_replace($model,$replace,$content);
       }
      
       return $str;
   }
  
}
?>

<mynav limit="0,10" order="sort asc">
   <a href="[field.id]">[field.name]</a><br/>
</mynav>
