thinkphp 实现一个model()的类 ,为什么会出现页面错误?配置文件都没写,DUBUG模式也开启了。

php thinkphp

<code>    //IndexAction.class.php下的
    public function index(){

        //从model类中获取数据
        $m=new Model('User');
        $arr=$m->select(); 
        var_dump($arr);
    }

    //config.php下的
    return array(
    /*
    配置数据库
     */
    'DB_HOST' => 'localhost',
    'DB_TYPE' => 'mysql',
    'DB_USER' => 'root',
    'DB_PWD' => 'root',
    'DB_NAME' => 'thinkphp',
    'DB_PREFIX' => 'tp_',
     );
</code>
Copy after login
Copy after login

就是这样了,php页面上出现":( 页面错误!请稍后再试~"

怎么解决啊?

怎么解决啊?

仔细看文档,以下链接

http://document.thinkphp.cn/manual_3_2.html#model_instance

解决办法可以从下面三个方法看看:

<code>$user = new \Home\Model\UserModel();
// or
$user = M('User');
// or
$user = D('User');

</code>
Copy after login

然后阐明一下几个观点:

1. 仔细阅读文档:

我还是坚持那个观点,仔细阅读文档可以解决80%的问题。

<code>1.仔细阅读文档,你遇到的问题就会少
2.如果你越到问题,这些问题的80%都可以解决

</code>
Copy after login

2.命名请规范

<code>$m=new Model('User');
$arr=$m->select(); 

</code>
Copy after login

看到$m $arr其实我是拒绝的,至少你得叫个$user吧。
