pass parameter from url to cakephp

I need to send parameter from URL to cakephp controller. I have message table with two parameter 'ufrom' and 'uto'. in controller i want to save this values in message table.

I put in the URL:

http://localhost/ar/messages/add?ufrom=9&uto=3

in MessagesController i have function:

public function add() {

if(($this->request->query['uto'])and($this->request->query['ufrom'])){
        $this->Message->create();
        if ($this->Message->save($this->request->data)) {
            $this->set('addMessage',TRUE);
            $this->set('ufrom',$this->request->query['ufrom']);
            $this->set('uto',$this->request->query['uto']);
            $this->redirect(array('action' => 'index'));
        } else {
            $this->Session->setFlash(__('The message could not be saved. Please, try again.'));
        }

        $targets = $this->Message->Target->find('list');
        $this->set(compact('targets'));
}
else{
    $this->set('error',true);
}

}

and in add.ctp i have:

<?php
if(isset($error)){
  echo('error');
}
else{
  echo json_encode($ufrom);
  echo json_encode($uto);
  echo json_encode($addMessage);
}
?>

but when i use the above URL i see:

Notice (8): Undefined variable: ufrom [APP\View\Messages\add.ctp, line 6]null
Notice (8): Undefined variable: uto [APP\View\Messages\add.ctp, line 7]null
Notice (8): Undefined variable: addMessage [APP\View\Messages\add.ctp, line 8]null

and Nothing is stored in the database. I'm new in cakephp. please help.

The easiest way to pass parameters to the controller action would be to simply pass them through the action as arguments like so:

  public function add($ufrom,$uto)

Your URL should look like:

http://localhost/ar/messages/add/9/3

Secondarily if the data is coming from the URL you wouldn't use this->request->data , simply :

$message = array("Message"=>array("ufrom"=>$ufrom,"uto"=>$uto));
$this->Message->save($message);

here i can suggest you to use params like below

http://www.example.com/tester/retrieve_test/good/1/accepted/active

but if you need to use like this way

http://www.example.com/tester/retrieve_test?status=200&id=1yOhjvRQBgY

you can get the value like below

echo $this->params['url']['id'];
echo $this->params['url']['status'];

in your case would be like

echo $this->params['url']['uto'];
echo $this->params['url']['ufrom'];
