birthday Field Type
A date field that specializes in handling birthdate data.
Can be rendered as a single text box, three text boxes (month, day, and year), or three select boxes.
This type is essentially the same as the date type, but with a more appropriate default for the years option. The years option defaults to 120 years ago to the current year.
Underlying Data Type | can be DateTime , string , timestamp , or array
(see the input option) |
Rendered as | can be three select boxes or 1 or 3 text boxes, based on the widget option |

Overridden Options
years
type: array
default: 120 years ago to the current year
List of years available to the year field type. This option is only
relevant when the widget
option is set to choice
.
Inherited options
These options inherit from the date type:
widget
type: string
default: choice
The basic way in which this field should be rendered. Can be one of the following:
input
type: string
default: datetime
The format of the input data - i.e. the format that the date is stored on your underlying object. Valid values are:
string
(e.g.2011-06-05
)datetime
(aDateTime
object)array
(e.g.array('year' => 2011, 'month' => 06, 'day' => 05)
)timestamp
(e.g.1307232000
)
The value that comes back from the form will also be normalized back into this format.
Caution
If timestamp
is used, DateType
is limited to dates between
Fri, 13 Dec 1901 20:45:54 GMT and Tue, 19 Jan 2038 03:14:07 GMT on 32bit
systems. This is due to a limitation in PHP itself.
months
type: array
default: 1 to 12
List of months available to the month field type. This option is only relevant
when the widget
option is set to choice
.
days
type: array
default: 1 to 31
List of days available to the day field type. This option is only relevant
when the widget
option is set to choice
:
1
'days' => range(1,31)
format
type: integer
or string
default: IntlDateFormatter::MEDIUM
Option passed to the IntlDateFormatter
class, used to transform user input
into the proper format. This is critical when the widget option is
set to single_text
, and will define how the user will input the data.
By default, the format is determined based on the current user locale: meaning
that the expected format will be different for different users. You
can override it by passing the format as a string.
For more information on valid formats, see Date/Time Format Syntax. For
example, to render a single text box that expects the user to enter yyyy-MM-dd
,
use the following options:
1 2 3 4
$builder->add('date_created', 'date', array(
'widget' => 'single_text',
'format' => 'yyyy-MM-dd',
));
data_timezone
type: string
default: system default timezone
Timezone that the input data is stored in. This must be one of the PHP supported timezones
user_timezone
type: string
default: system default timezone
Timezone for how the data should be shown to the user (and therefore also the data that the user submits). This must be one of the PHP supported timezones
These options inherit from the date type:
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 time 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).
invalid_message_parameters
type: array
default: array()
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('some_field', 'some_type', array(
// ...
'invalid_message' => 'You entered an invalid value - it should include %num% letters',
'invalid_message_parameters' => array('%num%' => 6),
));
read_only
2.1
The read_only
option was changed in 2.1 to render as a readonly
HTML attribute. Previously, it rendered as a disabled
attribute.
Use the disabled option if you need the old behavior.
type: Boolean
default: false
If this option is true, the field will be rendered with the readonly
attribute so that the field is not editable.
disabled
2.1
The disabled
option is new in version 2.1
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.
mapped
type: boolean
If you wish the field to be ignored when reading or writing to the object, you
can set the mapped
option to false
.
virtual
type: boolean
default: false
This option determines if the form will be mapped with data. This can be useful if you need a form to structure the view. See How to use the Virtual Form Field Option.
