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 5.5.0+ — 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). |
{# 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:
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:
{% 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:
{% 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):
{% 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:
{% 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>
