攻克CakePHP系列二 表单数据显示

CakePHP表单数据显示的方法步骤

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,PRIMARYKEY(`id`))ENGINE=MyISAMAUTO_INCREMENT=8DEFAULTCHARSET=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：

classDATABASE_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：

<?phpclassCompaniesControllerextendsAppController{var$name='Companies';

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

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

<?phpclassCompanyextendsAppModel{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><?phpforeach($companiesas$company): ?><tr><td><?phpecho$company['Company']['id']; ?></td><td><?phpecho$html->link($company['Company']['company'],'/companies/view/'.$company['Company']['id']); ?></td><td><?phpecho$company['Company']['price']; ?></td><td><?phpecho$company['Company']['change']; ?></td><td><?phpecho$company['Company']['lastudp']; ?></td></tr><?phpendforeach; ?></table>view.thtml：

<h1>Company: <?phpecho$company['Company']['company']?></h1><p><small>Id: <?phpecho$company['Company']['id']?></small></p><p>Price: <?phpecho$company['Company']['price']?></p><p>Change: <?phpecho$company['Company']['change']?></p><p>LastUpdate: <?phpecho$company['Company']['lastudp']?></p>访问http://localhost/cakephp/companies即可运行测试程序。
