攻克CakePHP系列二 表单数据显示

首先建立数据库cake_ext，并执行如下sql文：
CREATE TABLE `companies` (
`id` int(11) NOT NULL auto_increment,
`company` varchar(50) NOT NULL,
`price` decimal(8,2) NOT NULL,
`change` decimal(8,2) NOT NULL,
`lastudp` date NOT NULL,
PRIMARY KEY (`id`)
) ENGINE=MyISAM AUTO_INCREMENT=8 DEFAULT CHARSET=utf8;

-- ----------------------------
-- Records
-- ----------------------------
INSERT INTO `companies` VALUES ('1', '3m Co', '71.72', '0.02', '2008-10-21');
INSERT INTO `companies` VALUES ('2', 'Alcoa Inc', '29.01', '0.42', '2008-10-20');
INSERT INTO `companies` VALUES ('3', 'AT&T Inc.', '31.61', '-0.48', '2008-10-21');
INSERT INTO `companies` VALUES ('4', 'Boeing Co.', '75.43', '0.53', '2008-10-13');
INSERT INTO `companies` VALUES ('5', 'United Technologies Corporation', '63.26', '0.55', '2008-10-09');
INSERT INTO `companies` VALUES ('6', 'Intel Corporation', '19.88', '0.31', '2008-10-15');
INSERT INTO `companies` VALUES ('7', 'Exxon Mobil Corp', '68.10', '-0.43', '2008-10-17');
如下图所示建立工程：


数据库配置文件如下：
class DATABASE_CONFIG
{
var $default = array('driver' => 'mysql',
'connect' => 'mysql_connect',
'host' => 'localhost',
'login' => 'root',
'password' => 'root',
'database' => 'cake_ext',
'prefix' => '');

var $test = array('driver' => 'mysql',
'connect' => 'mysql_connect',
'host' => 'localhost',
'login' => 'root',
'password' => 'root',
'database' => 'cake_ext',
'prefix' => '');
}
companies_controller.php：
<?php
class CompaniesController extends AppController
{
var $name = 'Companies';

function index()
{
$this->set('companies', $this->Company->findAll());
}

function view($id = null)
{
$this->Company->id = $id;
$this->set('company', $this->Company->read());
}
}
?>
company.php：

<?php
class Company extends AppModel
{
var $name = 'Company';
}
?>
index.thtml：
<h1>Test companies</h1>
<table>
<tr>
<th>Id</th>
<th>company</th>
<th>price</th>
<th>change</th>
<th>last update</th>
</tr>
<?php foreach ($companies as $company): ?>
<tr>
<td><?php echo $company['Company']['id']; ?></td>
<td>
<?php echo $html->link($company['Company']['company'], "/companies/view/".$company['Company']['id']); ?>
</td>
<td><?php echo $company['Company']['price']; ?></td>
<td><?php echo $company['Company']['change']; ?></td>
<td><?php echo $company['Company']['lastudp']; ?></td>
</tr>
<?php endforeach; ?>
</table>
view.thtml：
<h1>Company: <?php echo $company['Company']['company']?></h1>
<p><small>Id: <?php echo $company['Company']['id']?></small></p>
<p>Price: <?php echo $company['Company']['price']?></p>
<p>Change: <?php echo $company['Company']['change']?></p>
<p>LastUpdate: <?php echo $company['Company']['lastudp']?></p>
访问http://localhost/cakephp/companies即可运行测试程序。
