我是CakePHP的新手,在我解决每个问题时仍在学习。
我有两张桌子:顾客和商店。在商店表中,我有一个名为customer_id的外键,它持有客户表中的客户ID。
在CakePHP中,我为上表创建了控制器,模型和视图。从CustomerController.php中查看操作,我试图获得与客户ID匹配的商店。
CustomerController.php页面:
class CustomersController extends AppController
{
public function index()
{
$customers = $this->Customers->find('all'); // Find all the records from the database.
$this->set('customers', $customers);
$stores = $this->Customers->Stores->find('all');
$this->set('stores', $stores);
}
public function view($id = NULL)
{
$customer = $this->Customers->get($id); // Find a record for individual record.
$this->set('customer', $customer);
// $stores = $this->Customers->Stores->find('all');
$stores = $this->Customers->Stores->find('list', [
'keyField' => 'id',
'valueField' => 'store_name'
]);
$this->set('store', $stores);
}
}
SQL表:
CREATE TABLE IF NOT EXISTS `customers` (
`id` int(11) NOT NULL AUTO_INCREMENT,
`first_name` varchar(50) DEFAULT NULL,
`last_name` varchar(50) DEFAULT NULL,
PRIMARY KEY (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=latin1 AUTO_INCREMENT=4 ;
--
-- Dumping data for table `customers`
--
INSERT INTO `customers` (`id`, `first_name`, `last_name`) VALUES
(1, 'Ray', 'Mak'),
(2, 'John', 'Smith'),
(3, 'Mike', 'Gorge');
-- --------------------------------------------------------
--
-- Table structure for table `states`
--
CREATE TABLE IF NOT EXISTS `states` (
`id` int(11) NOT NULL AUTO_INCREMENT,
`state_name` varchar(100) DEFAULT NULL,
PRIMARY KEY (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=latin1 AUTO_INCREMENT=6 ;
--
-- Dumping data for table `states`
--
INSERT INTO `states` (`id`, `state_name`) VALUES
(1, 'TX'),
(2, 'VA'),
(3, 'WI'),
(4, 'AZ'),
(5, 'FL');
-- --------------------------------------------------------
--
-- Table structure for table `stores`
--
CREATE TABLE IF NOT EXISTS `stores` (
`id` int(11) NOT NULL AUTO_INCREMENT,
`customer_id` int(11) DEFAULT NULL,
`store_name` varchar(50) DEFAULT NULL,
`corp_name` varchar(200) DEFAULT NULL,
`street_address` varchar(200) DEFAULT NULL,
`city` varchar(50) DEFAULT NULL,
`state_id` int(11) DEFAULT NULL,
`zipcode` int(11) DEFAULT NULL,
PRIMARY KEY (`id`),
KEY `customers_idx` (`customer_id`),
KEY `states_idx` (`state_id`)
) ENGINE=InnoDB DEFAULT CHARSET=latin1 AUTO_INCREMENT=2 ;
查看页面:
<pre>
<?php
print_r(json_encode($store));
print_r(h($customer));
?>
</pre>
我可以使用带有左连接的自定义SQL查询来获取结果,但是在cakephp中,当id匹配时,我如何从另一个表中获取数据会让人感到困惑。
任何帮助将不胜感激:)

您在评论中提到您解决了问题,但如果您在CustomersController :: view函数中使用以下代码,则$ id不代表商店ID。
$stores = $this->Customers->Stores->find('all',[ 'conditions' => array('Stores.id' => $id)]);
为了获得与客户相关的商店,您必须参考以下代码
$stores = $this->Customers->Stores->findByCustomerId($id);
//where $id represents customer_id from stores table
