time Field Type

CAUTION: You are browsing the documentation for Symfony 2.5 which is not maintained anymore. Consider upgrading your projects to Symfony 3.2.

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

2.3Since 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 (a DateTime 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 type time. User's input will be validated against the form hh:mm (or hh: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

2.2The 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

by_reference

default: false

The DateTime classes are treated as immutable objects.

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 or ArrayAccess 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

2.3The 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.

Form Variables

Variable Type Usage
widget mixed The value of the widget option.
with_minutes Boolean The value of the with_minutes option.
with_seconds Boolean The value of the with_seconds option.
type string Only present when widget is single_text and HTML5 is activated, contains the input type to use (datetime, date or time).
