How to combine two string in twig?

Question

I want to do something like this:

{% set c=a+b %}

Where a and b are strings.
How can I do it?

Answer 1

Use the "~" operator. This will concatenate your two strings. The "+" operator cannot be used to combine strings.

You would get this:

{% set c=a~b %}

More info: The "+" operator: Adds two objects together (the operands are casted to numbers).
