如何用当前年份替换存储在 Drupal Twig 模板中的对象/数组属性中的占位符字符串？

Question

I have a custom block which returns an array with a text-field.

How can I replace the string %current_year% in the #text property of the array with the current year in my twig template?

'0' => array(4)
   '#type' => string(14) "processed_text"
   '#text' => string UTF-8(119) "The current year is %current_year%."

Answer 1

I'm assuming your array/object is passed to the template as the variable myObject .

You can render the string in the #text property while replacing the placeholder as follows:

{{ attribute(myObject, '#text') | replace({"%current_year%": ("now"|date("Y"))}) }}

... or use an intermediate variable ...

{% set currentYear = "now"|date("Y") %}
{{ attribute(myObject, '#text') | replace({"%current_year%": currentYear}) }}
