如何在CodeIgniter 3中安装条令

未完成，并且是针对CI2的

所以我给你们一个我自己检查过的教程，它正在运行

---

我知道这是鼓励用户的。安装原则

（以下说明修改自：）

条令可以安装在以下设备上：

从命令行（例如Windows:Start>cmd）更改到应安装文件的文件夹（例如htdocs/my_项目）

使用Composer安装文件：

a。运行

C:\>composer安装/orm

或：

b。在composer.json文件中定义以下要求：

{
"require": {
    "doctrine/orm": "*"
  }
}

然后从命令行调用

composer install

Composer将安装一个包含多个子文件夹和数百个php文件的文件夹

vendor

。将此

供应商

文件夹移动到CodeIgniter应用程序树中。为简单起见，您可以将其放在此处：

/application
    /config
    /controllers
    /libraries
       Doctrine.php <-- the doctrine bootstrap/wrapper file
    /third_party
/vendor  <-- the folder installed by Composer. don't touch the files or folders below it -- install all together as one happy family.
    /bin
    /composer
    /doctrine
    /symfony
    autoload.php  <-- Doctrine.php opens this to load its files

您还可以将

vendor

中包含的所有文件夹和文件安装到其他地方，比如

third\u party

中，并相应地调整doctor.php

---

与CodeIgniter集成

（以下说明修改自：）

创建条令库：在文件夹

系统/应用程序/库

中，创建一个名为

条令.php

的文件，并将以下代码复制/粘贴到该文件中。这将是Doctrine2实体管理器的包装器/引导程序

您的doctor.php库文件应如下所示（您可以根据需要对其进行自定义）：

您需要将应用程序EntityManager注册到console工具，以便通过在应用程序目录中创建包含以下内容的cli-doctor.php文件来使用这些任务：

 <?php

 /**
 * Doctrine CLI bootstrap for CodeIgniter
 *
 */

 define('APPPATH', dirname(__FILE__) . '/');
define('BASEPATH', APPPATH . '/../system/');
define('ENVIRONMENT', 'development');

 require APPPATH.'libraries/Doctrine.php';

$doctrine = new Doctrine;
$em = $doctrine->em;

 $helperSet = new \Symfony\Component\Console\Helper\HelperSet(array(
    'db' => new \Doctrine\DBAL\Tools\Console\Helper\ConnectionHelper($em->getConnection()),
    'em' => new \Doctrine\ORM\Tools\Console\Helper\EntityManagerHelper($em)
));

 \Doctrine\ORM\Tools\Console\ConsoleRunner::run($helperSet);

 ?>

从数据库生成映射类：

php cli-doctrine.php orm:convert-mapping --from-database annotation models/Entities

如果出现此错误： 致命错误：调用未定义的函数doctor\Common\Cache\apc\u fetch（） 为PHP安装APC扩展：

sudo apt-get install php-apc
sudo /etc/init.d/apache2 restart

---

对于生产模式： Doctrine建议更改Doctrine.php中的以下设置： -使用真正的缓存系统，如APC -禁用EchoSqlLogger

-关闭AutogenerateProxy类

---

下一步是什么

要在CI中使用条令，请从控制器调用它，例如：

应用程序/controllers/my_controller.php：

function doctrine_orm()
{
    $this->load->library('Doctrine');
    $em = $this->doctrine->em;

    // do Doctrine stuff
    $productRepository = $em->getRepository('Product');
    $products = $productRepository->findAll();
    foreach ($products as $product):
        echo sprintf("-%s\n", $product->getName());
    endforeach;
}

---

然而，在执行任何条令之前，必须首先将数据库表映射到条令“实体”。在这里学习方法：
