枝條扔「array_intersect_key（）：參數＃1是不是數組」

我用樹枝修身框架和我有錯誤array_intersect_key(): Argument #1 is not an array我的模板是這樣的：枝條扔「array_intersect_key（）：參數＃1是不是數組」

{% extends 'main.tmpl' %} 
{% block content %} 
     <h2>Teams</h2> 
     <ul> 
     {% for team in teams %} 
      <li> 
       <img src="/images/{{ team.name }}.png"/> 
       <a href="/team/{{ team.name }}">{{ team.name }}</a> 
      </li> 
     {% endfor %} 
     </ul> 
{% endblock %}

和我的PHP代碼看起來像這樣：

$app->get('/teams', function() use ($app) { 
    return $app->render("teams", array(
     "teams" => array(array("name" => "Hello")) 
    )); 
});

我試着將模板var團隊更改爲組，並具有相同的效果。如何解決這個錯誤？爲什麼模板會拋出此異常？

和視圖類：

$twig = new Twig_Environment(new Twig_Loader_Filesystem('views')); 

class View extends \Slim\View { 
    protected function render($template) { 
     global $twig; 
     throw new Exception("Hello"); 
     if (substr($template, -5) !== '.tmpl') { 
      $template .= '.tmpl'; 
     } 
     return $twig->render($template, $this->data); 
    } 
}

UPDATE：堆棧跟蹤

我無法看到'array_intersect_key（）'在這個代碼中起作用。你可以請張貼堆棧跟蹤？ –

@crypticツ我已經添加了堆棧跟蹤 – jcubic

我能加入這個代碼來解決這個問題：

$data = get_class($this->data) == 'Slim\Helper\Set' ? $this->data->all() : $this->data; 
return $template->render($data);

內內渲染功能視圖。它將Slim chage數組連接到Set類的實例。
