Twig 用变量设置变量名 [TWIG/PHP] [英] Twig set a variable name with a variable [TWIG/PHP]

问题描述

如何在 Twig 中使用另一个值的值设置变量的名称?我认为它会是这样的:

How can I set a variable's name with the value of another value in Twig? I would think that It would go something like this:

{% set queCount = loop.index %}
{% for row2 in answer+queCount %}

但这行不通.还从中创建一个字符串将打破循环(因为它不搜索字符串).
我知道如何在 PHP 中执行此操作，所以为了澄清起见，这就是我想要实现的目标:

But this does not work. Also making a string from that will break the loop (because it does not search for a string).
I know how to do this in PHP so for clarification, this is what I would like to achieve:

$count = 1;
$args["answer$count"]

哪个返回

$args["answer1"]

但这一次，不是字符串而是操作性答案.

But this time, not with strings but the operant answer.

推荐答案

您可以使用 _context 变量

{% set queCount = loop.index %}
{% for row2 in _context['answer' ~ queCount] %}

这是关于 _context 和全局变量的文档
