控制器中的全局变量cakephp 2 [英] Global variable in controller cakephp 2

问题描述

在控制器中有一个全局变量的方法是什么？

我试图使用beforeFilter，但是不能从其他函数访问。 p>

只能使用 Configure :: read 和 Configure :: write
$ b

code>

解决方案

$ b

 类AppController extends Controller {
 public $ myGlobalVar; 
 
 public function beforeFilter（）
 {
 //这可以是任何数组，对象，字符串等..... 
 $ this-> myGlobalVar =test2; 
} 
} 
  

然后在其他控制器中，

  class TestController extends AppController {
 
 public function index（）{
 
 debug（$ this-> myGlobalVar）; 
} 
} 
  

What's the way to have a global variable inside a controller?

I have tried to do it using beforeFilter but it is not accessible from the others functions.

Can it only be done using Configure::read and Configure::write

解决方案

you can set variable accessible in any controller in your AppController

class AppController extends Controller {
    public $myGlobalVar;  

    public function beforeFilter()
    {
         //this can be anything array, object, string, etc .....
         $this->myGlobalVar = "test2";
    }
 }

then in your other controller you can access variable anywhere like this

class TestController extends AppController {

    public function index() {

        debug($this->myGlobalVar);
    }
}
