攻克CakePHP系列三 表单数据增删改

下面的代码是Cakephp下对表单数据的增加，删除，修改实现代码

这里声明一点，上例中不小心把数据库表中lastupd字段错打成lastudp，本例子予以更正。

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：

classCompaniesControllerextendsAppController
{
var$name='Companies';

functionindex()
{
$this->set('companies',$this->Company->findAll());
}

functionview($id= null)
{
$this->Company->id =$id;
$this->set('company',$this->Company->read());
}

functionadd()
{
if(!emptyempty($this->data))
{
if($this->Company->save($this->data))
{
$this->Flash('Your post has been saved.','/companies');
}
}
}

functionedit($id= null)
{
if(emptyempty($this->data))
{
$this->Company->id =$id;
$this->data =$this->Company->read();
}
else
{
if($this->Company->save($this->data['Company']))
{
$this->flash('Your post has been updated.','/companies');
}
}
}

functiondelete($id)
{
$this->Company->del($id);
$this->flash('The post with id: '.$id.' has been deleted.','/companies');
}
}
?>
company.php：

classCompanyextendsAppModel
{
var$name='Company';

var$validate=array(
'company'=> VALID_NOT_EMPTY,
'PRice'=> VALID_NOT_EMPTY,
'change'=> VALID_NOT_EMPTY,
'lastupd'=> VALID_NOT_EMPTY
);
}
?>
index.thtml：

Test companies

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

link('add',"/companies/add"); ?>

view.thtml：

Company:

Id:

Price:

Change:

LastUpdate:

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

add.thtml：

Add Company

Company:
input('Company/company',array('size'=>'40'))?>
tagErrorMsg('Company/company','Company is required.') ?>

Price:
input('Company/price',array('size'=>'40'))?>
tagErrorMsg('Company/company','Price is required.') ?>

Change:
input('Company/change',array('size'=>'40'))?>
tagErrorMsg('Company/change','Change is required.') ?>

Last Update:
input('Company/lastupd',array('size'=>'40'))?>
tagErrorMsg('Company/lastupd','Last Update is required.') ?>

submit('Save') ?> link('return',"/companies/index"); ?>

edit.thtml：

Edit Company

hidden('Company/id'); ?>

Company:
input('Company/company',array('size'=>'40'))?>
tagErrorMsg('Company/company','Company is required.') ?>

Price:
input('Company/price',array('size'=>'40'))?>
tagErrorMsg('Company/company','Price is required.') ?>

Change:
input('Company/change',array('size'=>'40'))?>
tagErrorMsg('Company/change','Change is required.') ?>

Last Update:
input('Company/lastupd',array('size'=>'40'))?>
tagErrorMsg('Company/lastupd','Last Update is required.') ?>

submit('Save') ?> link('return',"/companies/index"); ?>

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