cakephp - 在 cakePHP 中将组件变量传递给 Controller

Question

如何将在 cakePHP 组件的函数中声明的变量传递给 Controller ​​？我似乎无法解决这个问题。

Answer 1

您可以通过多种方式实现。基本上，您只需从 Controller 调用您需要的组件函数并返回值:

//In controller
$alteredData = $this->MyComponent->doSomethingWithData($data);

//In component
//You can also pass $data by reference if you want to alter it directly.
public function doSomethingWithData($data){
    //alter data in some way
    return $newData;
}

Per the documentation ，您还可以从组件直接访问 Controller ，因此您可以从组件调用 Controller 方法。

//In component
private $Controller;
public function initialize($controller){
    $this->Controller = $controller;
}

public function doSomethingWithData($data){
    //alter data in some way
    $this->Controller->set('data', $data);
}
