how to use a common data across action in a controller

Question

In my application am getting some values through webservice on the action index in controller. I want to use the same data in other actions also. How to implement it without calling webservice again.

Thanks.

Answer 1

You could save the data in the session, see also the sessions section in the manual.

Answer 2

$data = $this->MyModel->findAll(); // or whatever your select looks like
$this->Session->write('myData',$data);

Then, in your other controller actions (irrespective of which specific controller you're using, provided they have the Session component turned on):

if($this->Session->check('myData')){
    $data = $this->Session->read('myData');
}

Now your data lives in $data and can be easily be sent to a view, etc.

For all of this to work, you're going to need to add this as a class-level variable to each controller where you'll want this data available:

var $components = array('Session');

Good luck!
