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:
<?php classCompaniesControllerextendsAppController { 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:
<?php classCompanyextendsAppModel { 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。
