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：

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. PRIMARY KEY (id)
8. ) ENGINE=MyISAM AUTO_INCREMENT=8 DEFAULT CHARSET=utf8;
9. 10. -- ----------------------------
10. -- Records
11. -- ----------------------------
12. INSERT INTO companies VALUES ('1', '3m Co', '71.72', '0.02', '2008-10-21');
13. INSERT INTO companies VALUES ('2', 'Alcoa Inc', '29.01', '0.42', '2008-10-20');
14. INSERT INTO companies VALUES ('3', 'AT&T; Inc.', '31.61', '-0.48', '2008-10-21');
15. INSERT INTO companies VALUES ('4', 'Boeing Co.', '75.43', '0.53', '2008-10-13');
16. INSERT INTO companies VALUES ('5', 'United Technologies Corporation', '63.26', '0.55', '2008-10-09');
17. INSERT INTO companies VALUES ('6', 'Intel Corporation', '19.88', '0.31', '2008-10-15');
18. 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. class DATABASE_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' => '');

10. 11. **var** $test = **array**('driver' => 'mysql',

11. 'connect' => 'mysql_connect',
12. 'host' => 'localhost',
13. 'login' => 'root',
14. 'password' => 'root',
15. 'database' => 'cake_ext',
16. 'prefix' => '');
17. }

companies_controller.php：

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

company.php：

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