Question

This is my controller (unfinished obviously but to "do some magic" I first need to make it run):

    public function add($customer_id, $question_set_id, $order_value) {

        $customer_id = $this->params['url']['customer_id'];
        $question_set_id = $this->params['url']['question_set_id'];
        $order_value = $this->params['url']['order_value'];

        $possible_answer_model = ClassRegistry::init('PossibleAnswer');
        $question_model = ClassRegistry::init('Question');
        $order_model = ClassRegistry::init('Order');

        $order = $order_model -> find('first', array(
        'Order.question_set_id' => $question_set_id,
        'Order.value' => $order_value));

        $question = $question_model -> find('first', array(
        'Question.id' => $order['Order']['question_id']));

        $this -> set('question', $question);

        if ($question['Question']['kind'] != "o") {
            $this -> set('possible_answers', $possible_answer_model -> find('all', array(
            'PossibleAnswer.question_id' => $question['Question']['id'])));
        }
.
.
.

What I get is:

Warning (2): Missing argument 1 for AnswersController::add() [APP\Controller\AnswersController.php, line 10]

Warning (2): Missing argument 2 for AnswersController::add() [APP\Controller\AnswersController.php, line 10]

Warning (2): Missing argument 3 for AnswersController::add() [APP\Controller\AnswersController.php, line 10]

My link is:

/answers/add/?customer_id=1&question_set_id=1&order_value=1

Answer 1

The link needs to be

/answers/add/1/1/1

in order to map to

AnswersController::add($customer_id, $question_set_id, $order_value)

Regular query parameters have to be accessed through $this->params inside the controller, they are not passed as arguments to the action.
