如何在CakePHP表单中删除控制器名称

My code:

echo $this->Form->create('Usps', array(
    'inputDefaults' => array(
        'label' => false,
        'div' => false
    ),
    'id' => 'form-validate',
    'class' => 'form-horizontal',
    'novalidate' => 'novalidate',
    'url' => array('controller'=>'frondends','action' => 'tariffplan')
));

This produces www.example.com/frontends/tariffplan

I want to see : www.example.com/tariffplan I changed url as follows:

'url' => array('action' => 'tariffplan')

but this produces : www.example.com/usps/tariffplan

I searched google but no luck. Any help will be appreciated

Try this:

'url' => array('controller' => '/', 'action' => 'tariffplan')
