如何访问 TWIG 宏中的模板变量? [英] How can I access template variable in TWIG macro?

问题描述

我无法访问 TWIG 宏中的模板变量.

这是一个简化的例子:

{% set myname = "Ligio" %}{{ _self.pagedurl(1) }}{% 宏 pagedurl(page) %}嗨 {{ _self.myname }}！这是页码 {{ page }}{% endmacro %}

如何在不将变量 myname 传递给宏的情况下访问它?

解决方案

你不能.

如文档中所述:

<块引用>

作为 PHP 函数，宏无法访问当前模板变量.

您唯一的解决方案是将参数传递给宏:

{% import _self as flow %}{{ flow.pagedurl(1, "Ligio") }}{% 宏 pagedurl(page, myname) %}我是 }}！这是页码 {{ page }}{% endmacro %}

重要提示:

您可能已经注意到，在我的示例中，我调用 {% import _self as flow %}.
这是您必须做的事情:

<块引用>

当您在要使用它的模板中定义宏时，您可能很想通过 _self.input() 直接调用宏而不是导入它；即使看起来有效，这只是一个当前实现的副作用，它将不再适用树枝 2.x.

I'm not able to access template variable in TWIG macro.

Here is a simplified example:

{% set myname = "Ligio" %}
{{ _self.pagedurl(1) }}

{% macro pagedurl(page) %}
    Hi {{ _self.myname }}! This is Page Num {{ page }}
{% endmacro %}

How can I access the variable myname without passing it to the macro?

解决方案

You can not.

As stated in the documentation:

As PHP functions, macros don't have access to the current template variables.

Your only solution is to pass the parameter to the macro:

{% import _self as flow %}
{{ flow.pagedurl(1, "Ligio") }}

{% macro pagedurl(page, myname) %}
    Hi {{ myname }}! This is Page Num {{ page }}
{% endmacro %}

IMPORTANT NOTE:

You may have noticed in my example, I call {% import _self as flow %}.
This is something you MUST do:

When you define a macro in the template where you are going to use it, you might be tempted to call the macro directly via _self.input() instead of importing it; even if seems to work, this is just a side-effect of the current implementation and it won't work anymore in Twig 2.x.
