Overcoming CakePHP Series 3: Adding, Deleting and Modifying Form Data

The following code is the implementation code for adding, deleting, and modifying form data under Cakephp.

I would like to make a statement here. In the above example, the lastupd field in the database table was accidentally typed as lastudp. This example will be corrected.

Except the appeal field database is the same as the above example.

The project still uses the above example, as shown below:

The code is:

database.php: consistent with the above example.

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 $ value = array (
'Company '= & GT; Valid_not_empty,
'Price' = & GT; Valid_Not_empty,
'Change '= & GT; Vali D_not_empty,
'Lastupd '= & GT; Valid_not_empty
) ;
}
?>
index.thtml：

Test companies

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

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

view.thtml：

Company:

Id:

Price:

Change:

LastUpdate: < ?phpecho$company['Company']['lastupd']?>

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。
