"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 %}
Advanced usage:
{% for item in collection %}
<div {% if forloop.first %}class="first"{% endif %}>
Item {{ forloop.index }}: {{ item.name }}
</div>
{% endfor %}
You can also define a limit and offset much like SQL. Remember that offset
starts at 0 for the first item.
{% for item in collection limit:5 offset:10 %}
{{ item.name }}
{% end %}
To reverse the for loop simply use {% for item in collection reversed %}
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.
