for

"For" iterates over an array or collection. Several useful variables are available to you within the loop.

Basic usage:

{% for item in collection %}
  {{ forloop.index }}: {{ item.name }}
{% endfor %}

{% for item in (1..10) %}
  Item {{ i }}
{% endfor %}

Advanced usage:

{% for item in collection %}
  <div {% if forloop.first %}class="first"{% endif %}>
    Item {{ forloop.index }}: {{ item.name }}
  </div>
{% endfor %}

Elements in collection can be reversed by using a reversed keyword:

{% for item in collection reversed %}
  {{ item.name }}
{% endfor %}

You can also define a limit and offset. Remember that offset starts at 0 for the first item.


{% for item in collection limit: 5 offset: 10 %}
  {{ item.name }}
{% endfor %}

Available variables:

forloop.name 'item-collection'
forloop.length Length of the loop
forloop.index The current item‘s position in the collection; forloop.index starts at 1. This is helpful for non-programmers who start believe the first item in an array is 1, not 0.
forloop.index0 The current item‘s position in the collection where the first item is 0
forloop.rindex Number of items remaining in the loop (length - index) where 1 is the last item.
forloop.rindex0 Number of items remaining in the loop where 0 is the last item.
forloop.first Returns true if the item is the first item.
forloop.last Returns true if the item is the last item.
forloop.parentloop Provides access to the parent loop, if present.
