Cakephp country helper

Question

我对这个帮助器有一个问题：https://github.com/kshakirov/cakephp-lang-helper

这个帮助器给了我这个错误，我找不到原因：

Fatal Error

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

Answer 1

我猜问题在于LangHelper重写了父__construct方法，使其无法正确设置帮助器。将LangHelper的__construct()更改为：

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

您是否在AppController中激活了FormHelper

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

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