Checkboxes Fields

Checkboxes fields give you a group of checkbox (opens new window) inputs, and allow the author to select multiple values (or provide any number of custom values, when allowed).

# Settings

In addition to the standard field options, checkboxes fields have the following settings:

Checkbox Options – Define the options that will be available to authors. Each option contains a Label (shown to the author) and a Value (saved to the database), as well as a checkbox indicating whether it should be selected by default.
Allow custom options — Whether authors can provide “other” options, on-the-fly.

# Development

# Querying Elements with Checkboxes Fields

When querying for elements that have a checkboxes field, you can filter the results using a query param named after your field’s handle. Possible values include:

Value	Fetches elements…
`'foo'`	with a `foo` option checked (or `foo` provided as a custom value).
`'not foo'`	without a `foo` option checked (and without `foo` among custom values).
`['foo', 'bar']`	with `foo` or `bar` options selected (or `foo` provided as a custom value).
`['and', 'foo', 'bar']`	with `foo` and `bar` options selected (or among provided custom values).

Twig
PHP

{# Fetch entries with the 'foo' option checked #}
{% set entries = craft.entries()
  .myFieldHandle('foo')
  .all() %}

# Working with Checkboxes Field Data

If you have an element with a checkboxes field in your template, you can access its data using the field’s handle:

Twig
PHP

{% set value = entry.myFieldHandle %}

That will give you a craft\fields\data\MultiOptionsFieldData (opens new window) object that contains information about the selected values and the available options. This object can be used as an array; looping over it provides each selected option, in sequence:

Twig
PHP

{% for option in entry.myFieldHandle %}
  Label: {{ option.label }}
  Value: {{ option }} or {{ option.value }}
{% endfor %}

To loop through all available options, iterate over the options (opens new window) property:

Twig
PHP

{% for option in entry.myFieldHandle.options %}
  Label:   {{ option.label }}
  Value:   {{ option }} or {{ option.value }}
  Checked: {{ option.selected ? 'Yes' : 'No' }}
{% endfor %}

To see if any options are checked, use the length (opens new window) filter or empty (opens new window) test (or the count (opens new window) method in PHP):

Twig
PHP

{% if entry.myCheckboxesFieldHandle | length %}
  {# At least one option was selected! #}
{% endif %}

{% if entry.myCheckboxesFieldHandle is not empty %}
  {# Equivalent, but note that we’ve inverted the condition! #}
{% endif %}

To see if a specific option is checked, call contains() (opens new window) using the Value in question:

Twig
PHP

{% if entry.myCheckboxesFieldHandle.contains('foo') %}
  {# `foo` was selected! #}
{% endif %}

The in Twig test is equivalent:

{% if 'foo' in entry.myCheckboxesFieldHandle %}
  {# `foo` was selected! #}
{% endif %}

Custom values are also honored by both methods.

# Saving Checkboxes Fields

In an element or entry form (opens new window) that needs to save a value to a checkboxes field, you can use this template as a starting point:

{% set field = craft.app.fields.getFieldByHandle('myCheckboxesFieldHandle') %}

{# Include a hidden input first so Craft knows to clear the
   existing value, if no checkboxes are checked. #}
{{ hiddenInput('fields[myCheckboxesFieldHandle]', '') }}

<ul>
  {# Display native options as checkboxes: #}
  {% for option in field.options %}
    {% set checked = entry is defined
      ? entry.myCheckboxesFieldHandle.contains(option.value)
      : option.default %}

    <li>
      <label>
        <input
          type="checkbox"
          name="fields[myCheckboxesFieldHandle][]"
          value="{{ option.value }}"
          {% if checked %}checked{% endif %}>
        {{ option.label }}
      </label>
    </li>
  {% endfor %}

  {# Does this field allow custom options? #}
  {% if field.customOptions %}
    {# Loop over the *stored* values and output all the "invalid" ones as text fields: #}
    {% for option in entry.myCheckboxesFieldHandle | filter(o => not o.valid) %}
      <li>
        <label>
          <input
            type="text"
            name="fields[myCheckboxesFieldHandle][]"
            value="{{ option.value }}">
          {{ option.label }}
        </label>
      </li>
    {% endfor %}

    {# Provide one more input for new values: #}
    <li>
      <label>
        Other:
        <input
          type="text"
          name="fields[myCheckboxesFieldHandle][]">
      </label>
    </li>
  {% endif %}
</ul>
