Symfony2 / Twig - getting array from dynamic array key
提问by user2143356
In PHP I would do this:
在 PHP 中，我会这样做：
foreach( $array as $key => $value ) {
echo $another_array[$key];
}
I can't see how to do that in Twig (in Symfony2). I've tried various things, but this would seem the obvious answer, but it doesn't work. It returns a 'Item "the_index" for "Array" does not exist in' error.
我看不到如何在 Twig（在 Symfony2 中）中做到这一点。我尝试了各种方法，但这似乎是显而易见的答案，但它不起作用。它返回一个“项目“the_index”，因为“数组”不存在“错误”。
{% for value in array %}
{% set the_index = loop.index %}
{{ another_array.the_index }}
Any ideas?
有任何想法吗？

<ul>
{% for value in array %}
{% set the_index = attribute(another_array, loop.index) %}
<li>{{ the_index }}</li>
{% endfor %}
</ul>
