如何将cakePHP组件中函数声明的变量传递给控制器？我似乎无法解决这个问题。

Answer 1

你可以通过多种方式实现这一目标。基本上，您只需从控制器调用所需的组件功能并返回值：

//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控制器，以便从组件中调用控制器方法。

//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);
}

Answer 2

在cakePHP 3.x中（可能仅> 3.5）

// in Component
$this->getController()->set('var', $var);
