這里聲明一點，上例中不小心把數(shù)據(jù)庫表中l(wèi)astupd字段錯打成lastudp，本例子予以更正。

除上訴字段數(shù)據(jù)庫與上例一致。

工程仍沿用上例，如下圖：

代碼依次為：

database.php：與上例一致。

companies_controller.php：

  2. class?CompaniesController?extends?AppController
  3. {
  4. ????var?$name?=?'Companies';
  5. ????
  6. ????function?index()
  7. ????{
  8. ????????$this->set('companies',?$this->Company->findAll());
  9. ????}
  10. ????
  11. ????function?view($id?=?null)
  12. ????{
  13. ????????$this->Company->id?=?$id;
  14. ????????$this->set('company',?$this->Company->read());
  15. ????}
  16. ????
  17. ????function?add()
  18. ????{
  19. ????????if?(!emptyempty($this->data))
  20. ????????{
  21. ????????????if?($this->Company->save($this->data))
  22. ????????????{
  23. ????????????????$this->flash('Your?post?has?been?saved.','/companies');
  24. ????????????}
  25. ????????}
  26. ????}

  43. ????
  44. ????function?delete($id)

  11. ????);
  12. }
