how to access variabel passed in through redirect

	public function view() {
		if($this->request->is('post')) {
			$data = $this->request->data['HashAlgorithm'];
			$this->log($data);
			$this->redirect(array('controller' => 'HashResults' ,'action' => 'inputPlaintext', $data));
			
		}
		$conditions = array(
			'fields' => array('name'),
			'order' => array('name ASC')
		);
			
		$this->Session->destroy();
		$data = $this->HashAlgorithm->find('all', $conditions);
		$this->set('data', $data);
	}
	
	/**
	* in HashResult controller
	*/
	public function inputPlaintext() {
	// how do I access $data.
	}

try this

/**
    * in HashResult controller
    */
    public function inputPlaintext($data) {
    // how do I access $data.
    }

I think $data should be either string or number. Unlikely to handle array. But not 100% certain. Just try the above first and $this->log to let me know if it works.

$this->redirect(array('controller' => 'HashResults' ,'action' => 'inputPlaintext', 'myString' => 'Hello World'));

public function inputPlaintext() {
$data = $this->request->myString;
}
