Twig 嵌套数组

Question

我在 Twig 中渲染嵌套数组时遇到问题。这是我的 PHP 逻辑，我可以在其中获取名称 URL 等其他字段，但不能获取数组数据。请检查树枝代码，我想我在那里做错了什么。错误：在呈现模板期间抛出异常 ("Notice: Array to string conversion")。

foreach ($arrays as $array) {
    foreach ($array as $key => $value) {
        $allProjects[$key][] = $value;
    }
}

                      {% for project in projects %}
                        <tr>
                            <td>{{ project.name }}</td>
                            <td>{{ project.url }}</td>
                            <td>{{ project.assingedApprover }}</td>
                            <td></td>
                        </tr>
                    {% endfor %}

Json数据

    [
  {
    "name": "Resolute Energy Corporation",
    "url": "http://msu.edu",
    "assignedAprover": [
      {
        "firstName": "Joe",
        "lastName": "lastName"
      },
      {
        "firstName": "men",
        "lastName": "gen"
      }
    ]
  },
  {
    "name": "CBL & Associates Properties, Inc.",
    "url": "http://acquirethisname.com",
    "assignedAprover": [
      {
        "firstName": "Joe",
        "lastName": "lastName"
      },
      {
        "firstName": "men",
        "lastName": "gen"
      }
    ]
  },
]

Answer 1

由于 assignedAprover 是数组，您可以使用 for:

对其进行迭代

{% for project in projects %}
    <tr>
        <td>{{ project.name }}</td>
        <td>{{ project.url }}</td>
        {% for aprover in project.assignedAprover %}
        <td>{{ aprover['first_name'] }} {{ aprover['last_name'] }}</td>
        {% endfor %}
        <td></td>
    </tr>
{% endfor %}
