利用ThinkPHP连接数据库的增删改查的例题：用到的数据库表名Info表，Nation表
数据显示页面：MainController.class.php中的ShowInfo方法
//例题
//显示所有数据
public function ShowInfo()
{
$model = D("Info");
$attr = $model->field("Info.Code as InfoCode,Info.Name as InfoName,Info.Sex,Nation.Name as NationName,Info.Birthday ")->join("Nation on Info.Nation=Nation.Code")->select(); $this->assign("shuju",$attr);
$this->display();
//var_dump($attr);
} //删除数据的操作方法
public function ShanChu($code)
{
$model = D("Info");
$z = $model->delete($code);
if($z)
{
$this->success("删除成功",U("ShowInfo"));
}
else
{
$this->error("删除失败");
}
}
模板的数据显示：ShowInfo.html
