Question

我正在尝试基于我在之前的stackoverflow帖子中遇到的上一个问题来实现php-active记录 setting up sparks with php-activerecord in codeigniter

好的，所以我把那些代码放在构造函数中，我的错误就消失了（phew）。

但现在测试那个orm是有效的。我使用以下代码

在models文件夹中创建了名为User.php的模型

<?php

class User extends ActiveRecord\Model {


}  

?>

然后我继续在我的数据库中创建一个表来测试机智php-activerecord以查看orm是否有效。所以我决定使用下面的sql代码

创建一个名为“spark”的数据库，其中包含一个名为“users”的表

CREATE TABLE IF NOT EXISTS `users` (
  `id` int(11) NOT NULL AUTO_INCREMENT,
  `username` varchar(32) NOT NULL,
  `password` varchar(32) NOT NULL,
  PRIMARY KEY (`id`)
) ENGINE=InnoDB  DEFAULT CHARSET=latin1 AUTO_INCREMENT=3 ;

--
-- Dumping data for table `users`
--

INSERT INTO `users` (`id`, `username`, `password`) VALUES
(1, 'shawn', ''),
(2, 'justin', '');

我的database.php也配置为匹配表，如下所示：

$db['default'] = array(
    'dsn'   => '',
    'hostname' => 'localhost',
    'username' => 'root',
    'password' => '',
    'database' => 'spark',
    'dbdriver' => 'mysqli',
    'dbprefix' => '',
    'pconnect' => TRUE,
    'db_debug' => TRUE,
    'cache_on' => FALSE,
    'cachedir' => '',
    'char_set' => 'utf8',
    'dbcollat' => 'utf8_general_ci',
    'swap_pre' => '',
    'autoinit' => TRUE,
    'encrypt' => FALSE,
    'compress' => FALSE,
    'stricton' => FALSE,
    'failover' => array()
);

将数据库dats排序，所以我打开了welcome.php控制器并将以下代码添加到索引方法中，如下所示

public function index()
    {


        $users = User::all();

        echo "<pre>";
        print_r($users);
    }

我在浏览器中运行它，我得到以下错误，如下所示

Answer 1

问题清楚地显示在异常消息中：

消息：未捕获异常'ActiveRecord \ DatabaseException'，消息'找不到ActiveRecord \ MysqliAdapter！'在C：\ xampp \ htdocs \ orm \ sparks \ php-activerecord \ 0.0.2 \ vendor \ php -

它正在尝试为ActiveRecord库加载mysqli适配器而不是找到它。该库未完全安装（可能缺少可选的mysqli模块），或者未正确设置包含路径以自动加载其类。

Answer 2

PHPActiveRecord 建立在 PDO 之上，而不是 mysqli。该库不支持 mysqli。您看到此错误消息的原因是您已指定 'dbdriver' => 'mysqli' 但 PDO 没有 mysqli 驱动程序，也没有您尝试使用的此库。

要修复错误，只需指定 mysql 作为驱动程序。

'dbdriver' => 'mysql'

使用codeigniter实现php-activerecord的问题
