ThinkPHP示例之表单处理：自动获取表单数据生成数据对象

 本示例对提交的表单数据进行处理，自动创建数据对象和进行自动验证和填充。
 
 
 {$vo.title}
 [{$vo.create_time|date='Y-m-d H:i:s',###}]

 {$vo.content|nl2br}

 
   
 {$page}

 

IndexAction.class.php

class IndexAction extends Action{
    public function index() {
      //自定义
   $Form=M('Form');
   import("@.ORG.Page"); //导入分页类
   $count = $Form->count();    //计算总数
   $p = new Page ( $count, 2 );
   $list=$Form->order('id desc')->limit(6)->select();
   $p->setConfig('header','篇记录');
   $p->setConfig('prev',"<");
   $p->setConfig('next','>');
   $p->setConfig('first','<<');
   $p->setConfig('last','>>');
   $page = $p->show ();
   $this->assign( "page", $page );
   $this->assign ( "list", $list );
   $this->display();
    }

}
?>

在Lib目录下新建ORG目录新建Page.class.php

    protected $rollPage   ;
 // 分页显示定制
