攻克CakePHP系列三表单数据增删改_PHP

除上诉字段数据库与上例一致。

工程仍沿用上例，如下图：

代码依次为：

database.php：与上例一致。

companies_controller.php：

1. class CompaniesController extends AppController
2. {
3. var $name = 'Companies';
5. function index()
6. {
7. $this->set('companies', $this->Company->findAll());
8. }
10. function view($id = null)
11. {
12. $this->Company->id = $id;
13. $this->set('company', $this->Company->read());
14. }
16. function add()
17. {
18. if (!emptyempty($this->data))
19. {
20. if ($this->Company->save($this->data))
21. {
22. $this->flash('Your post has been saved.','/companies');
23. }
24. }
25. }
27. function edit($id = null)
28. {
29. if (emptyempty($this->data))
30. {
31. $this->Company->id = $id;
32. $this->data = $this->Company->read();
33. }
34. else
35. {
36. if ($this->Company->save($this->data['Company']))
37. {
38. $this->flash('Your post has been updated.','/companies');
39. }
40. }
41. }
43. function delete($id)
44. {
45. $this->Company->del($id);
46. $this->flash('The post with id: '.$id.' has been deleted.', '/companies');
47. }
48. }
49. ?>

company.php：

1. class Company extends AppModel
2. {
3. var $name = 'Company';
5. var $validate = array(
6. 'company' => VALID_NOT_EMPTY,
7. 'price' => VALID_NOT_EMPTY,
8. 'change' => VALID_NOT_EMPTY,
9. 'lastupd' => VALID_NOT_EMPTY
10. );
11. }
12. ?>

index.thtml：

1. Test companies

2. foreach ($companies as $company): ?>
   endforeach; ?>

   Id	company	price	change	last update
   $company['Company']['id']; ?>	$html->link($company['Company']['company'], "/companies/view/".$company['Company']['id']); ?> $html->link('Delete', "/companies/delete/{$company['Company']['id']}", null, 'Are you sure?')?>	$company['Company']['price']; ?>	$company['Company']['change']; ?>	$company['Company']['lastupd']; ?>

4. $html->link('add', "/companies/add"); ?>

view.thtml：

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

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

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

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

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

6. 
   
8. $html->link('edit', "/companies/edit/".$company['Company']['id']); ?>

add.thtml：

1. Add Company

edit.thtml：

1. Edit Company

如此访问http://localhost/cakephp/companies即可测试代码。
