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：

  1. CREATE TABLE `companies` (
  2. `id` int(11) NOT NULL auto_increment,
  3. `company` varchar(50) NOT NULL,
  4. `price` decimal(8,2) NOT NULL,
  5. `change` decimal(8,2) NOT NULL,
  6. `lastudp` date NOT NULL,
  7. PRIMARYKEY(`id`)
  8. )ENGINE=MyISAMAUTO_INCREMENT=8DEFAULTCHARSET=utf8;
  10. -- ----------------------------
  11. -- Records
  12. -- ----------------------------
  13. INSERT INTO `companies` VALUES ('1', '3m Co', '71.72', '0.02', '2008-10-21');
  14. INSERT INTO `companies` VALUES ('2', 'Alcoa Inc', '29.01', '0.42', '2008-10-20');
  15. INSERT INTO `companies` VALUES ('3', 'AT&T Inc.', '31.61', '-0.48', '2008-10-21');
  16. INSERT INTO `companies` VALUES ('4', 'Boeing Co.', '75.43', '0.53', '2008-10-13');
  17. INSERT INTO `companies` VALUES ('5', 'United Technologies Corporation', '63.26', '0.55', '2008-10-09');
  18. INSERT INTO `companies` VALUES ('6', 'Intel Corporation', '19.88', '0.31', '2008-10-15');
  19. 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：

  1. classDATABASE_CONFIG
  2. {
  3. var$default=array('driver'=>'mysql',
  4. 'connect'=>'mysql_connect',
  5. 'host'=>'localhost',
  6. 'login'=>'root',
  7. 'password'=>'root',
  8. 'database'=>'cake_ext',
  9. 'prefix'=>'');
  11. var$test=array('driver'=>'mysql',
  12. 'connect'=>'mysql_connect',
  13. 'host'=>'localhost',
  14. 'login'=>'root',
  15. 'password'=>'root',
  16. 'database'=>'cake_ext',
  17. 'prefix'=>'');
  18. }

companies_controller.php：

  1. <?php
  2. classCompaniesControllerextendsAppController
  3. {
  4. var$name='Companies';
  6. functionindex()
  7. {
  8. $this->set('companies',$this->Company->findAll());
  9. }
  11. functionview($id= null)
  12. {
  13. $this->Company->id =$id;
  14. $this->set('company',$this->Company->read());
  15. }
  16. }
  17. ?>

company.php：

  1. <?php
  2. classCompanyextendsAppModel
  3. {
  4. var$name='Company';
  5. }
  6. ?>

index.thtml：

  1. <h1>Test companies</h1>
  2. <table>
  3. <tr>
  4. <th>Id</th>
  5. <th>company</th>
  6. <th>price</th>
  7. <th>change</th>
  8. <th>last update</th>
  9. </tr>
  10. <?phpforeach($companiesas$company): ?>
  11. <tr>
  12. <td><?phpecho$company['Company']['id']; ?></td>
  13. <td>
  14. <?phpecho$html->link($company['Company']['company'],"/companies/view/".$company['Company']['id']); ?>
  15. </td>
  16. <td><?phpecho$company['Company']['price']; ?></td>
  17. <td><?phpecho$company['Company']['change']; ?></td>
  18. <td><?phpecho$company['Company']['lastudp']; ?></td>
  19. </tr>
  20. <?phpendforeach; ?>
  21. </table>

view.thtml：

  1. <h1>Company: <?phpecho$company['Company']['company']?></h1>
  2. <p><small>Id: <?phpecho$company['Company']['id']?></small></p>
  3. <p>Price: <?phpecho$company['Company']['price']?></p>
  4. <p>Change: <?phpecho$company['Company']['change']?></p>
  5. <p>LastUpdate: <?phpecho$company['Company']['lastudp']?></p>

访问http://localhost/cakephp/companies即可运行测试程序。
