ThinkPHP示例之自定义标签：定义查询数据库的标签
 本示例定义一个查询数据库的标签，可以使模板直接按条件查找指定的数据库并列表显示，本例仅是展示自定义标签的方便之处，可以进一步扩充和完善,打造属于自已的标签体系
 
  

 

 

 
序列
标题
内容
 

  

   
{$article.id}
   
{$article.title}
   
{$article.content}
  
 

 

 
 示例源码
控制器自定义标签类
 highlight_file(LIB_PATH.'TagLib/TagLibarticle.class.php');
 
 

 

'TAGLIB_PRE_LOAD' => 'article' ,

function _initialize() {
 import("@.Mylibs.Tag.TagLibArticle");
}

'APP_AUTOLOAD_PATH'=> 'Think.Util.,@.Mylibs.Tag.',

'APP_AUTOLOAD_PATH'=> 'Think.Util.,@.Mylibs.Tag.',
'TAGLIB_PRE_LOAD' => 'test' ,
