for

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

Basic usage:

Example
Copy
{% for item in collection %}
{{ forloop.index }}: {{ item.name }}
{% endfor %}
Example
Copy
{% for item in (1..10) %}
Item {{ item }}
{% endfor %}

Advanced usage:

Example
Copy
{% 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:

Example
Copy
{% 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.

Example
Copy
{% 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.
