# forloop

Information about a parent [`for` loop](https://shopify.dev/docs/api/liquid/tags/for).

## Properties

* * first

    [boolean](https://shopify.dev/docs/api/liquid/basics#boolean)

  * Returns `true` if the current iteration is the first. Returns `false` if not.

  * index

    [number](https://shopify.dev/docs/api/liquid/basics#number)

  * The 1-based index of the current iteration.

  * index0

    [number](https://shopify.dev/docs/api/liquid/basics#number)

  * The 0-based index of the current iteration.

  * last

    [boolean](https://shopify.dev/docs/api/liquid/basics#boolean)

  * Returns `true` if the current iteration is the last. Returns `false` if not.

  * length

    [number](https://shopify.dev/docs/api/liquid/basics#number)

  * The total number of iterations in the loop.

  * parentloop

    [forloop](https://shopify.dev/docs/api/liquid/objects/forloop)

  * The parent `forloop` object.

    If the current `for` loop isn't nested inside another `for` loop, then `nil` is returned.

    ```liquid
    {% for i in (1..3) -%}
      {% for j in (1..3) -%}
        {{ forloop.parentloop.index }} - {{ forloop.index }}
      {%- endfor %}
    {%- endfor %}
    ```

    ##### Code

    ```
    {% for i in (1..3) -%}
      {% for j in (1..3) -%}
        {{ forloop.parentloop.index }} - {{ forloop.index }}
      {%- endfor %}
    {%- endfor %}
    ```

    ## Output

    ```html
    1 - 1
    1 - 2
    1 - 3


    2 - 1
    2 - 2
    2 - 3


    3 - 1

    3 - 3
    ```

  * rindex

    [number](https://shopify.dev/docs/api/liquid/basics#number)

  * The 1-based index of the current iteration, in reverse order.

  * rindex0

    [number](https://shopify.dev/docs/api/liquid/basics#number)

  * The 0-based index of the current iteration, in reverse order.

```json
{
  "first": true,
  "index": 1,
  "index0": 0,
  "last": false,
  "length": 4,
  "rindex": 3
}
```

##### Example

```
{
  "first": true,
  "index": 1,
  "index0": 0,
  "last": false,
  "length": 4,
  "rindex": 3
}
```

### Use the `forloop` object

```liquid
{% for page in pages -%}
  {%- if forloop.length > 0 -%}
    {{ page.title }}{% unless forloop.last %}, {% endunless -%}
  {%- endif -%}
{% endfor %}
```

##### Code

```
{% for page in pages -%}
  {%- if forloop.length > 0 -%}
    {{ page.title }}{% unless forloop.last %}, {% endunless -%}
  {%- endif -%}
{% endfor %}
```
