time Field Type
A field to capture time input.
This can be rendered as a text field, a series of text fields (e.g. hour,
minute, second) or a series of select fields. The underlying data can be stored
as 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 | can be various tags (see below) |

Basic Usage
This field type is highly configurable, but easy to use. The most important
options are input
and widget
.
Suppose that you have a startTime
field whose underlying time data is a
DateTime
object. The following configures the time
type for that
field as two different choice fields:
1 2 3 4
$builder->add('startTime', 'time', array(
'input' => 'datetime',
'widget' => 'choice',
));
The input
option must be changed to match the type of the underlying
date data. For example, if the startTime
field's data were a unix timestamp,
you'd need to set input
to timestamp
:
1 2 3 4
$builder->add('startTime', 'time', array(
'input' => 'timestamp',
'widget' => 'choice',
));
The field also supports an array
and string
as valid input
option
values.
Field Options
empty_value
2.3
Since Symfony 2.3, empty values are also supported if the expanded
option is set to true.
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 the
multiple
option is 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,
));
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
.
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.12:17:26
)datetime
(aDateTime
object)array
(e.g.array('hour' => 12, 'minute' => 17, 'second' => 26)
)timestamp
(e.g.1307232000
)
The value that comes back from the form will also be normalized back into this format.
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
.
model_timezone
type: string
default: system default timezone
Timezone that the input data is stored in. This must be one of the PHP supported timezones.
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
.
view_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.
widget
type: string
default: choice
The basic way in which this field should be rendered. Can be one of the following:
choice
: renders one, two (default) or three select inputs (hour, minute, second), depending on the with_minutes and with_seconds options.text
: renders one, two (default) or three text inputs (hour, minute, second), depending on the with_minutes and with_seconds options.single_text
: renders a single input of typetime
. User's input will be validated against the formhh:mm
(orhh:mm:ss
if using seconds).
Caution
Combining the widget type single_text
and the with_minutes option
set to false
can cause unexpected behavior in the client as the input
type time
might not support selecting an hour only.
with_minutes
2.2
The with_minutes
option was introduced in Symfony 2.2.
type: Boolean
default: true
Whether or not to include minutes in the input. This will result in an additional input to capture minutes.
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.
Overridden Options
error_bubbling
default: false
Inherited Options
These options inherit from the form type:
data
type: mixed default: Defaults to field of the underlying object (if there is one)
When you create a form, each field initially displays the value of the corresponding property of the form's domain object (if an object is bound to the form). If you want to override the initial value for the form or just an individual field, you can set it in the data option:
1 2 3
$builder->add('token', 'hidden', array(
'data' => 'abcdef',
));
Note
The default values for form fields are taken directly from the
underlying data structure (e.g. an entity or an array).
The data
option overrides this default value.
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.
error_mapping
type: array
default: empty
This option allows you to modify the target of a validation error.
Imagine you have a custom method named matchingCityAndZipCode
that validates
whether the city and zip code match. Unfortunately, there is no "matchingCityAndZipCode"
field in your form, so all that Symfony can do is display the error on top
of the form.
With customized error mapping, you can do better: map the error to the city field so that it displays above it:
1 2 3 4 5 6 7 8
public function setDefaultOptions(OptionsResolverInterface $resolver)
{
$resolver->setDefaults(array(
'error_mapping' => array(
'matchingCityAndZipCode' => 'city',
),
));
}
Here are the rules for the left and the right side of the mapping:
- The left side contains property paths;
- If the violation is generated on a property or method of a class, its path
is simply
propertyName
; - If the violation is generated on an entry of an
array
orArrayAccess
object, the property path is[indexName]
; - You can construct nested property paths by concatenating them, separating
properties by dots. For example:
addresses[work].matchingCityAndZipCode
; - The left side of the error mapping also accepts a dot
.
, which refers to the field itself. That means that any error added to the field is added to the given nested field instead; - The right side contains simply the names of fields in the form.
inherit_data
2.3
The inherit_data
option was introduced in Symfony 2.3. Before, it
was known as virtual
.
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".
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),
));
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
.
read_only
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.

The value of the with_minutes option. |
with_seconds | Boolean |
