Checkboxes Fields

Checkboxes fields give you a group of checkboxes.

#Settings

Checkboxes fields have the following settings:

• Checkbox Options – Define the checkboxes that will be available in the field. You even get to set the option values and labels separately, and choose which ones should be checked by default.

#Querying Elements with Checkboxes Fields

When querying for elements that have a Checkboxes field, you can filter the results based on the Checkboxes field data using a query param named after your field’s handle.

Possible values include:

| Value | Fetches elements… | - | - | 'foo' | with a foo option checked. | 'not foo' | without a foo option checked. | ['foo', 'bar'] | with foo or bar options selected. | ['and', 'foo', 'bar'] | with foo and bar options selected.

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

// Fetch entries with the 'foo' option checked
$entries = \craft\elements\Entry::find()
    ->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 your Checkboxes field’s handle:

{% set value = entry.myFieldHandle %}

$value = $entry->myFieldHandle %}

That will give you a craft3:craft\fields\data\MultiOptionsFieldData object that contains the field data.

To loop through all checked options, iterate over the field value:

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

foreach ($entry->myFieldHandle as $option) {
    // label: $option->label
    // value: $option or $option->value
}

To loop through all available options, iterate over the options property:

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

foreach ($entry->myFieldHandle->options as $option) {
    // label:   $option->label
    // value:   $option or $option->value
    // checked: $option->selected ? 'Yes' : 'No'
}

To see if any options are checked, use the length filter or count method:

{% if entry.myFieldHandle|length %}

if (count($entry->myFieldHandle)) {

To see if a particular option is checked, use contains()

{% if entry.myFieldHandle.contains('foo') %}

if ($entry->myFieldHandle->contains('foo')) {

#Saving Checkboxes Fields

If you have an element form, such as an entry form, that needs to contain a Checkboxes field, you can use this template as a starting point:

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

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

  {% for option in field.options %}
    {% set checked = entry is defined
      ? entry.myFieldHandle.contains(option.value)
      : option.default %}

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