Save data using AJAX and CakePHP

Question

I\'ve spent today researching how to save data using an ajax request in cakephp and have got now where, the documentation on the cakephp website seems a bit lacking for this

Answer 1

 public function add_project() {
    $this->autoRender = false;
    $this->layout = 'ajax';
    if ($this->RequestHandler->isAjax()) {
        $this->Project->set($this->request->data);
        $this->request->data['Project']['user_id'] = $this->Session->read('Auth.User.id');
        $this->request->data['Project']['created_by'] = $this->Session->read('Auth.User.id');
        $this->request->data['Project']['updated_by'] = $this->Session->read('Auth.User.id');
        //$this->request->data['Skill']['accept_decline'] = 0;
        $this->User->set($this->request->data['Project']);
        Configure::write('debug', 0);
        if ($this->Project->validates(array('fieldList' => array('project_title', 'show_on', 'summary')))) {

            if ($this->Project->save($this->request->data, false)) {
                $response['status'] = 'succses';
                $response['message'] = 'data  sent';
                echo json_encode($response);
                exit();
            } else {
                $response['status'] = 'error';
                $response['model'] = 'Project';
                $response['message'] = 'data not sent';
                echo json_encode($response);
                exit();
            }
        } else {
            $response['status'] = 'invalid';
            $response['model'] = 'Project';
            $errors = $this->Project->validationErrors;
            $response['errors'] = $errors;
            echo json_encode($response);
            exit();
        }
    }
}
