Twig template - Loop iteration sum items in loop

symfony templates for-loop twig iteration

Variables in Twig have scopes, therefore first you need to set the variable before loop:

{% set totalPrice = 0 %}

Then make the sum inside the loop:

{% for product in products %}    {% set totalPrice = totalPrice + (product.quantity * product.price) %}{% endfor %}

And in the and print the sum in proper format:

{{ totalPrice|number_format(2, '.', ',') }}
