Question

我正在使用带有Slim框架的Twig，我收到错误array_intersect_key(): Argument #1 is not an array我的模板看起来像这样：

{% 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 %}

我的php代码如下：

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

我尝试将模板var团队更改为组并具有相同的效果。如何解决这个错误？为什么模板会抛出此异常？

和View类：

$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);
    }
}

更新：Stacktrace

Answer 1

我可以通过添加此代码来修复它：

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

里面的渲染函数里面的视图。它将Slim chage数组接合到Set类的实例。

Twig throw“array_intersect_key（）：参数＃1不是数组”
