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. CREATETABLE`companies`(
2. `id`int(11)NOTNULLauto_increment,
3. `company`varchar(50)NOTNULL,
4. `price`decimal(8,2)NOTNULL,
5. `change`decimal(8,
6. `lastudp`dateNOTNULL,
7. PRIMARYKEY(`id`)
8. )ENGINE=MyISAMAUTO_INCREMENT=8DEFAULTCHARSET=utf8;
10. ------------------------------
11. --Records
12. ------------------------------
13. INSERTINTO`companies`VALUES('1','3mCo','71.72','0.02','2008-10-21');
14. INSERTINTO`companies`VALUES('2','AlcoaInc','29.01','0.42','2008-10-20');
15. INSERTINTO`companies`VALUES('3','AT&TInc.','31.61','-0.48','2008-10-21');
16. INSERTINTO`companies`VALUES('4','BoeingCo.','75.43','0.53','2008-10-13');
17. INSERTINTO`companies`VALUES('5','UnitedTechnologiesCorporation','63.26','0.55','2008-10-09');
18. INSERTINTO`companies`VALUES('6','IntelCorporation','19.88','0.31','2008-10-15');
19. INSERTINTO`companies`VALUES('7','ExxonMobilCorp','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'=>'');

11. var

    $test=

    array

    ('driver'=>'MysqL',
12. 'prefix'=>'');
13. }

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. ?>

index.thtml：

1. Testcompanies

4. Id
5. company
6. price
7. change
8. lastupdate
10. PHP

    foreach

    ($companies

    as

    $company):?>
12. PHPecho$company['Company']['id'];?>
14. PHPecho$html->link($company['Company']['company'],"/companies/view/".$company['Company']['id']);?>
16. PHPecho$company['Company']['price'];?>
17. PHPecho$company['Company']['change'];?>
18. PHPecho$company['Company']['lastudp'];?>
20. PHP

    endforeach

    ;?>

view.thtml：

1. Company:PHPecho$company['Company']['company']?>

2. Id:PHPecho$company['Company']['id']?>

3. Price:PHPecho$company['Company']['price']?>

4. Change:PHPecho$company['Company']['change']?>

5. LastUpdate:PHPecho$company['Company']['lastudp']?>

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