将参数传递给Twig宏

Question

我将2个参数传递给Twig宏，但其中只有一个似乎被传递

{{currentPage}} //this is outputting the current page e.g. home 


{% macro render_menu(links, currentPage) %}

{% import _self as subnav %}

{% for code, link in links %}

{{currentPage}} //this is NOT outputting the current page

<li class="{{ code == currentPage ? 'active' }} {{ link.sublinks ? 'dropdown' }}">

我需要使用currentPage来启用“活动”菜单项

Answer 1

你在哪里叫宏？ 代码的那部分缺失了。 注意宏有自己的范围，这意味着它们不知道任何变量，你必须明确地传递它们

macro.twig

{% macro render_menu(links, currentPage) %}
    {% import _self as subnav %}
    {% for link in links %}
        <li class="{{ link.code == currentPage ? 'active' }} {{ link.sublinks ? 'dropdown' }}">
            <a href="{{ link.code }}">{{ link.code }}</a>
        </li>
    {% endfor %}
{% endmacro %}

main.twig

{% import 'macro.twig' as macro %}

{{ macro.render_menu(links, currentPage) }}
