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。
