datetime Field Type

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

date_widget

type: string default: choice

Defines the widget option for the date type

time_widget

type: string default: choice

Defines the widget option for the time type

widget

type: string default: null

Defines the widget option for both the date type and time type. This can be overridden with the date_widget and time_widget 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 (a DateTime object)
  • 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.

empty_value

type: string or Boolean

This option determines whether or not a special "empty" option (e.g. "Choose an option") will appear at the top of a select widget. This option only applies if both the expanded and multiple options are set to false.

  • Add an empty value with "Choose an option" as the text:

    1
    2
    3
    $builder->add('states', 'choice', array(
        'empty_value' => 'Choose an option',
    ));
    
  • Guarantee that no "empty" value option is displayed:

    1
    2
    3
    $builder->add('states', 'choice', array(
        'empty_value' => false,
    ));
    

If you leave the empty_value option unset, then a blank (with no text) option will automatically be added if and only if the required option is false:

1
2
3
4
// a blank (with no text) option will be added
$builder->add('states', 'choice', array(
    'required' => false,
));

Inherited options

These options inherit from the form 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

New in version 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

New in version 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.
