如何访问树枝中的动态变量名?

How to access dynamic variable names in twig?(如何访问树枝中的动态变量名?)

问题描述

我在树枝中有一些变量，比如

I have some variables in twig like

placeholder1
placeholder2
placeholderx

要调用它们，我正在遍历对象数组发票"

To call them, I am looping through the array of objects "invoices"

{% for invoices as invoice %}
    need to display here the placeholder followed by the invoice id number
    {{ placeholedr1 }}

推荐答案

我刚刚遇到了同样的问题 - 使用这个第一个答案，经过一些额外的研究发现 {{ attribute(_context, 'placeholder'~invoice.id) }} 应该可以工作(_context 是按名称包含所有对象的全局上下文对象)

I just had the same issue - and using this first answer and after some additional research found the {{ attribute(_context, 'placeholder'~invoice.id) }} should work (_context being the global context object containing all objects by name)
