How to print twig variables inside html code

Question

I created a variable, like this :

{% set checkboxHTML = \'Edit\' %}


        

Answer 1

You have to use set, like this:

{% set checkboxHTML = '<button class="btn btn-default btn-md" data-id="' ~ b.id ~ '">Edit</button>' %}

Documentation: https://twig.symfony.com/doc/2.x/tags/set.html

Answer 2

Alternative method to solve this is using the expanded {% set %}
Do note when using this method, the content is considered being safe

{% set checkboxHTML %}
    <button class="btn btn-default btn-md" data-id="{{ b.id }}">Edit</button>
{% endset %}
