Cakephp 2.5 pass data to controller action

I am using CakePhp 2.5 and i am into a view that have the $data array,

This is the result of a search form and i can var_dump and see is there.

How can i pass this same $data array to an action of the same controller that show the output in PDF format? ?

I try :

echo $this->Html->Link("PDF", array('controller' => 'Verify',
                                     'action'=> 'resultsPdf', $data),);

I just get : array (size=0) empty

You can't pass an array as an argument to a controller function like that. One way around that would be to encode the array as a json string, and then decode in the controller action.

$encoded = json_encode($data);
echo $this->Html->Link(
    "PDF", 
    array(
        'controller' => 'Verify',
        'action'=> 'resultsPdf',
        $encoded
    )
);

Controller:

function resultsPdf($data) {
    $data = json_decode($data);
}

Another approach would be through named parameters:

$encoded = json_encode($data);
echo $this->Html->Link(
    "PDF", 
    array(
        'controller' => 'Verify',
        'action'=> 'resultsPdf',
        'encoded' => $encoded
    )
);

Controller:

function resultsPdf() {
    $data = json_decode($this->params['named']['encoded']);
}
