Accessing array values using array key from Twig
提问by Joseph Woodward
Does anyone know how (of if it's even possible!) to do this in Twig? I can't see anything in the documentation as to whether it's possible.
有谁知道如何（甚至可能！）在 Twig 中做到这一点？我在文档中看不到任何关于它是否可能的内容。
The PHP array is structured as below:
PHP 数组的结构如下：
$data['data']['a']['title'] = 'Title 1';
$data['data']['a']['title'] = 'Title 2';
$data['data']['b']['title'] = 'Title 3';
Twig template code below:
Twig模板代码如下：
{% for letter in 'a'..'z' %}
{{ letter }}
<ul>
{% for key, item1 in data %}
{% for item2 in item1 %}
<li>{{ item2[key].title }}</li>
{% endfor %}
{% endfor %}
</ul>
{% endfor %}
Edit:After further investigation, it appears the attribute (see http://twig.sensiolabs.org/doc/functions/attribute.html) function should do the job but I am unsure as to how to use it in these circumstances.
编辑：经过进一步调查，似乎属性（参见http://twig.sensiolabs.org/doc/functions/attribute.html）函数应该可以完成这项工作，但我不确定如何在这些情况下使用它。
Many thanks
非常感谢

Have you just tried this:
你有没有试过这个：
attribute(item2, key).title
