tp_关联查询

[php]代码库

<?php
	class MessageModel extends RelationModel{
		protected $_auto=array(
			array('time','time',1,'function'),  //自动填充
			array('uid','getId',1,'callback')
			
		);

		protected $_link=array(
			'User'=> array(  
     			'mapping_type'=>BELONGS_TO,
          		'class_name'=>'User',
          		'foreign_key'=>'uid',
				'mapping_name'=>'user',
				'mapping_fields'=>'username',
				'as_fields'=>'username：uname',//变为评级状态字段冲突可改  必解继承RelationModel
			),
			
		
		);
		protected function getId(){
			return $_SESSION['id'];
		}
	}
?>



//自动填充的功能
	//$message->time=time();
	//$message->uid=$_SESSION['id'];
自动获取值

//关联查询时用relation(true)
$arr=$message->relation(true)->limit($page->firstRow.','.$page->listRows)->select();
