DateIntervalType Field
This field allows the user to select an interval of time. For example, if you want to allow the user to choose how often they receive a status email, they could use this field to choose intervals like every "10 minutes" or "3 days".
The field can be rendered in a variety of different ways (see widget) and can be configured to
give you a DateInterval
object, an ISO 8601 duration string (e.g. P1DT12H
)
or an array (see input).
Underlying Data Type | can be DateInterval , string or array (see the input option) |
Rendered as | single text box, multiple text boxes or select fields - see the widget option |
Default invalid message | Please choose a valid date interval. |

Tip
The full list of options defined and inherited by this form type is available running this command in your app:
1 2
# replace 'FooType' by the class name of your form type
$ php bin/console debug:form FooType
Basic Usage
This field type is highly configurable. The most important options are input and widget.
You can configure a lot of different options, including exactly which range options to show (e.g. don't show "months", but do show "days"):
1 2 3 4 5 6 7 8 9 10
$builder->add('remindEvery', DateIntervalType::class, [
'widget' => 'integer', // render a text field for each part
// 'input' => 'string', // if you want the field to return a ISO 8601 string back to you
// customize which text boxes are shown
'with_years' => false,
'with_months' => false,
'with_days' => true,
'with_hours' => true,
]);
Field Options
days
type: array
default: 0 to 31
List of days available to the days field type. This option is only relevant
when the widget
option is set to choice
:
1 2 3 4 5
// values displayed to users range from 0 to 30 (both inclusive)
'days' => range(1, 31),
// values displayed to users range from 1 to 31 (both inclusive)
'days' => array_combine(range(1, 31), range(1, 31)),
placeholder
type: string
or array
If your widget option is set to choice
, then this field will be represented
as a series of select
boxes. The placeholder
option can be used to
add a "blank" entry to the top of each select box:
1 2 3
$builder->add('remindEvery', DateIntervalType::class, [
'placeholder' => '',
]);
Alternatively, you can specify a string to be displayed for the "blank" value:
1 2 3
$builder->add('remindEvery', DateIntervalType::class, [
'placeholder' => ['years' => 'Years', 'months' => 'Months', 'days' => 'Days'],
]);
hours
type: array
default: 0 to 24
List of hours available to the hours field type. This option is only relevant
when the widget
option is set to choice
:
1 2 3 4 5
// values displayed to users range from 0 to 23 (both inclusive)
'hours' => range(1, 24),
// values displayed to users range from 1 to 24 (both inclusive)
'hours' => array_combine(range(1, 24), range(1, 24)),
input
type: string
default: dateinterval
The format of the input data - i.e. the format that the interval is stored on your underlying object. Valid values are:
string
(a string formatted with ISO 8601 standard, e.g.P7Y6M5DT12H15M30S
)dateinterval
(aDateInterval
object)array
(e.g.['days' => '1', 'hours' => '12',]
)
The value that comes back from the form will also be normalized back into this format.
labels
type: array
default: (see below)
The labels displayed for each of the elements of this type. The default values
are null
, so they display the "humanized version" of the child names (Invert
,
Years
, etc.):
1 2 3 4 5 6 7 8 9 10
'labels' => [
'invert' => null,
'years' => null,
'months' => null,
'weeks' => null,
'days' => null,
'hours' => null,
'minutes' => null,
'seconds' => null,
]
minutes
type: array
default: 0 to 60
List of minutes available to the minutes field type. This option is only relevant
when the widget
option is set to choice
:
1 2 3 4 5
// values displayed to users range from 0 to 59 (both inclusive)

1 2 3 4 5
// values displayed to users range from 0 to 11 (both inclusive)
'months' => range(1, 12),
// values displayed to users range from 1 to 12 (both inclusive)
'months' => array_combine(range(1, 12), range(1, 12)),
seconds
type: array
default: 0 to 60
List of seconds available to the seconds field type. This option is only relevant
when the widget
option is set to choice
:
1 2 3 4 5
// values displayed to users range from 0 to 59 (both inclusive)
'seconds' => range(1, 60),
// values displayed to users range from 1 to 60 (both inclusive)
'seconds' => array_combine(range(1, 60), range(1, 60)),
weeks
type: array
default: 0 to 52

widget
type: string
default: choice
The basic way in which this field should be rendered. Can be one of the following:
choice
: renders one to six select inputs for years, months, weeks, days, hours, minutes and/or seconds, depending on the with_years, with_months, with_weeks, with_days, with_hours, with_minutes and with_seconds options. Default: Three fields for years, months and days.text
: renders one to six text inputs for years, months, weeks, days, hours, minutes and/or seconds, depending on the with_years, with_months, with_weeks, with_days, with_hours, with_minutes and with_seconds options. Default: Three fields for years, months and days.integer
: renders one to six integer inputs for years, months, weeks, days, hours, minutes and/or seconds, depending on the with_years, with_months, with_weeks, with_days, with_hours, with_minutes and with_seconds options. Default: Three fields for years, months and days.single_text
: renders a single input of typetext
. User's input will be validated against the formPnYnMnDTnHnMnS
(orPnW
if using only weeks).
with_days
type: Boolean
default: true
Whether or not to include days in the input. This will result in an additional input to capture days.
Caution
This can not be used when with_weeks is enabled.
with_hours
type: Boolean
default: false
Whether or not to include hours in the input. This will result in an additional input to capture hours.
with_invert
type: Boolean
default: false
Whether or not to include invert in the input. This will result in an additional
checkbox.
This can not be used when the widget option is set to single_text
.
with_minutes
type: Boolean
default: false
Whether or not to include minutes in the input. This will result in an additional input to capture minutes.
with_months
type: Boolean
default: true
Whether or not to include months in the input. This will result in an additional input to capture months.
with_seconds
type: Boolean
default: false
Whether or not to include seconds in the input. This will result in an additional input to capture seconds.
with_weeks
type: Boolean
default: false
Whether or not to include weeks in the input. This will result in an additional input to capture weeks.
Caution
This can not be used when with_days is enabled.
with_years
type: Boolean
default: true
Whether or not to include years in the input. This will result in an additional input to capture years.
years
type: array
default: 0 to 100
List of years available to the years field type. This option is only relevant
when the widget
option is set to choice
:
1 2 3 4 5
// values displayed to users range from 0 to 99 (both inclusive)
'years' => range(1, 100),
// values displayed to users range from 1 to 100 (both inclusive)
'years' => array_combine(range(1, 100), range(1, 100)),
Overridden Options
invalid_message
type: string
default: This value is not valid
This is the validation error message that's used if the data entered into this field doesn't make sense (i.e. fails validation).
This might happen, for example, if the user enters a nonsense string into
a TimeType field that cannot be converted
into a real time or if the user enters a string (e.g. apple
) into a
number field.
Normal (business logic) validation (such as when setting a minimum length for a field) should be set using validation messages with your validation rules (reference).
Inherited Options
These options inherit from the form type:
attr
type: array
default: []
If you want to add extra attributes to an HTML field representation
you can use the attr
option. It's an associative array with HTML attributes
as keys. This can be useful when you need to set a custom class for some widget:
1 2 3
$builder->add('body', TextareaType::class, [
'attr' => ['class' => 'tinymce'],
]);
See also
Use the row_attr
option if you want to add these attributes to
the form type row element.
data
type: mixed
default: Defaults to field of the underlying structure.
When you create a form, each field initially displays the value of the corresponding property of the form's domain data (e.g. if you bind an object to the form). If you want to override this initial value for the form or an individual field, you can set it in the data option:
1 2 3 4 5 6
use Symfony\Component\Form\Extension\Core\Type\HiddenType;
// ...
$builder->add('token', HiddenType::class, [
'data' => 'abcdef',
]);
Caution
The data
option always overrides the value taken from the domain data
(object) when rendering. This means the object value is also overridden when
the form edits an already persisted object, causing it to lose its
persisted value when the form is submitted.
disabled
type: boolean
default: false
If you don't want a user to modify the value of a field, you can set the disabled option to true. Any submitted value will be ignored.
help
type: string
or TranslatableInterface
default: null
Allows you to define a help message for the form field, which by default is rendered below the field:
1 2 3 4 5 6 7 8 9 10 11 12 13
use Symfony\Component\Translation\TranslatableMessage;
$builder
->add('zipCode', null, [
'help' => 'The ZIP/Postal code for your credit card\'s billing address.',
])
// ...
->add('status', null, [
'help' => new TranslatableMessage('order.status', ['%order_id%' => $order->getId()], 'store'),
])
;
help_attr
type: array
default: []
Sets the HTML attributes for the element used to display the help message of the form field. Its value is an associative array with HTML attribute names as keys. These attributes can also be set in the template:
1 2 3
{{ form_help(form.name, 'Your name', {
'help_attr': {'class': 'CUSTOM_LABEL_CLASS'}
}) }}
help_html
type: boolean
default: false
By default, the contents of the help
option are escaped before rendering
them in the template. Set this option to true
to not escape them, which is
useful when the help contains HTML elements.
inherit_data
type: boolean
default: false
This option determines if the form will inherit data from its parent form. This can be useful if you have a set of fields that are duplicated across multiple forms. See How to Reduce Code Duplication with "inherit_data".
Caution
When a field has the inherit_data
option set, it uses the data of
the parent form as is. This means that
Data Transformers won't be
applied to that field.
invalid_message_parameters
type: array
default: []
When setting the invalid_message
option, you may need to
include some variables in the string. This can be done by adding placeholders
to that option and including the variables in this option:
1 2 3 4 5
$builder->add('someField', SomeFormType::class, [
// ...
'invalid_message' => 'You entered an invalid value, it should include %num% letters',
'invalid_message_parameters' => ['%num%' => 6],
]);
mapped
type: boolean
default: true
If you wish the field to be ignored when reading or writing to the object,
you can set the mapped
option to false
.
row_attr
type: array
default: []
An associative array of the HTML attributes added to the element which is used to render the form type row:
1 2 3
$builder->add('body', TextareaType::class, [
'row_attr' => ['class' => 'text-editor', 'id' => '...'],
]);
See also
Use the attr
option if you want to add these attributes to
the form type widget element.
