Question

我正在尝试定义一个将传递给Controller的Action的变量，如下所示

public function index($branch = null) {
        //padmanabha-nagar
        //jp-nagar
        $branch = "padmanabha-nagar";

        $this->loadModel('Branch');

        // Check if the Branch is valid
        if(!empty($branch)){
            $this->Branch->recursive = -1;
            $branch_result = $this->Branch->find('first', array('order' => array('Branch.name ASC'), 'conditions' => array('Branch.slug' => $branch)));

          //debug($branch_result);

            // Fetch the Branch ID
            if(!empty($branch_result)){
                $branch_id = $branch_result['Branch']['id'];
            } else {
                return $this->redirect(array('controller' => 'pages', 'action' => 'home'));
            }

            // Fetch the Gallery Images
            $this->Gallery->recursive = -1;
            $this->Paginator->settings = $this->paginate;
            $galleries = $this->Gallery->find('all', array('conditions' => array('Gallery.branch_id' => $branch_id)));

            //debug($galleries);
        }

        $this->set(compact('galleries', 'branch_result'));
    }

但是当我尝试访问$ branch时，似乎没有设置。我需要做任何其他配置才能获得内容吗？

Answer 1

尝试将分支添加到此行，如下所示： $ this-＆gt; set（compact（'galleries'，'branch_result'，'branch'））;

Answer 2

您正在编写输入变量

public function index($branch = null) {
        //padmanabha-nagar
        //jp-nagar
        $branch = "padmanabha-nagar"; <= you are over writing the input variable
        ...

你可以这样做

        $branch = !empty($branch)?$branch:"padmanabha-nagar";

Answer 3

您可以使用

创建一个变量来分类

  $branches = null;

而不是动作，然后使用

变量

  $this->branches

CakePHP控制器方法变量
