CakePHP的國家幫手

Question

我有這個助手的一個問題：https://github.com/kshakirov/cakephp-lang-helper

這個助手給我這個錯誤，我沒有找到原因：

Fatal Error 

Error: Call to a member function input() on a non-object 
File: \app\View\Helper\LangHelper.php 
Line: 670 

Answer 1

我猜問題是，LangHelper覆蓋父__construct方法，防止蛋糕從正確設置助手。將LangHelper的__construct()更改爲以下內容：

public function __construct(View $View, $settings = array()) { 
    parent::__construct($View, $settings); 
    $this->mapper = $this->parseLangHeaders(); 
    $this->langCode = $this->findLangCode(); 
    $this->countryCode = $this->findCountryCode(); 
} 

Answer 2

你激活的AppController的FormHelper？

App::uses('FormHelper', 'View/Helper'); // Don't forget this one in Cake 2.x 

class AppController extends Controller 
{ 
    public 
    $helpers = array('Form'); 
}
