Cakephp国家帮手

Question

我对此助手有疑问：https://github.com/kshakirov/cakephp-lang-helper

这个助手给我这个错误，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

我猜测问题是LangHelper会覆盖父__construct方法，从而阻止Cake正确设置Helper。将LangHelper的__construct()更改为以下内容：

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

您是否激活了FormHelper中的AppController？

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

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