Twig – The loop Variable


The loop variable

Inside of a for loop block you can access some special variables:

Variable Description
loop.index The current iteration of the loop. (1 indexed)
loop.index0 The current iteration of the loop. (0 indexed)
loop.revindex The number of iterations from the end of the loop (1 indexed)
loop.revindex0 The number of iterations from the end of the loop (0 indexed)
loop.first True if first iteration
loop.last True if last iteration
loop.length The number of items in the sequence
loop.parent The parent context
1
2
3
{% for user in users %}
    {{ loop.index }} - {{ user.username }}
{% endfor %}

Note

The loop.length, loop.revindex, loop.revindex0, and loop.last variables are only available for PHP arrays, or objects that implement the Countable interface. They are also not available when looping with a condition.
