datetime Field Type
This field type allows the user to modify data that represents a specific
date and time (e.g. 1984-06-05 12:15:30).
Can be rendered as a text input or select tags. The underlying format of the
data can be a DateTime object, a string, a timestamp or an array.
| Underlying Data Type | can be DateTime, string, timestamp, or array (see the input option) |
| Rendered as | single text box or three select fields |

Field Options
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 12:15:00)datetime(aDateTimeobject)array(e.g.array(2011, 06, 05, 12, 15, 0))timestamp(e.g.1307276100)
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.
date_format
type: integer or string default: IntlDateFormatter::MEDIUM
Defines the format option that will be passed down to the date field.
See the date type's format option
for more details.
hours
type: array default: 0 to 23
List of hours available to the hours field type. This option is only relevant
when the widget option is set to choice.
minutes
type: array default: 0 to 59
List of minutes available to the minutes field type. This option is only
relevant when the widget option is set to choice.
seconds
type: array default: 0 to 59
List of seconds available to the seconds field type. This option is only
relevant when the widget option is set to choice.
years
type: array default: five years before to five years after 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.
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)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.
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
Inherited options
These options inherit from the field 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.
