基于会话的多步骤表单cakehp

基本上我有三种形式。我的表单中有一个动作，我想使用会话创建3个步骤的表单。我希望当我点击下一个按钮时，它会验证表单1，如果成功，则重定向到表单2。。与form3的wise类似，但将所有数据保留在会话中，在第三步中，运行操作并将所有数据添加到数据库中
我只需要在我的插入在我的操作addjob中运行之前检查会话中的条件。请帮我做这件事。

我的主要问题是如何在一个会话变量中获取所有的post数据，并在插入之前一步一步地进行检查。。

我是cakepp的学习者，对课程没有足够的了解。如果你是一个专家，那么请这样做。

 public function addjob($id = NULL) {   
    $this->layout = "layout_registration_old";        
    $this->loadcategory();
    $this->loadcargo(); 
   //$this->loadsubcategory(); 
    $this->getCountries(); 
    $this->getstates(); 
    if ($this->request->is('put') || $this->request->is('post')) {          
        if (isset($id)) {
            $this->Job->id = $id;
        } else {
            $this->request->data['Job']['status'] = 1;  
            $this->request->data['Job']['job_type'] = 1; //this is used to update the job type private or public.
            $this->Job->create();
        }
        $this->Job->set($this->request->data);
        if ($this->Job->AddEdit()) { // ADDEdit is the validation name in model              
            if ($this->Job->save($this->request->data['Job'], false)) {
                if (isset($id)) {
                $this->Session->setFlash(__('Job has been updated sucessfully.'));
                } else {
                $this->Session->setFlash(__('Job has been added succesfully.'));
                }
                $this->redirect(array('controller' => 'jobs', 'action' => 'index'));
            }
        } else {
            $errors = $this->Job->validationErrors;
            $this->Session->setFlash(__('Please check your entry.'), 'flash_error');
        }
    }
    if (isset($id)) {
        $this->request->data = $this->Job->find('first', array('conditions' => array('id' => base64_decode($id))));
    }
}
