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 {{ item }}
{% 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.
