date Field Type

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:

'days' => range(1,31)

placeholder¶

type: string or array

If your widget option is set to choice, then this field will be represented as a series of select boxes. The placeholder option can be used to add a “blank” entry to the top of each select box:

$builder->add('dueDate', 'date', array(
    'placeholder' => '',
));

Alternatively, you can specify a string to be displayed for the “blank” value:

$builder->add('dueDate', 'date', array(
    'placeholder' => array('year' => 'Year', 'month' => 'Month', 'day' => 'Day')
));

format¶

type: integer or string default: IntlDateFormatter::MEDIUM (or yyyy-MM-dd if widget is single_text)

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:

$builder->add('date_created', 'date', array(
    'widget' => 'single_text',
    // this is actually the default format for single_text
    'format' => 'yyyy-MM-dd',
));

html5¶

type: boolean default: true

If this is set to true (the default), it’ll use the HTML5 type (date, time or datetime) to render the field. When set to false, it’ll use the text type.

This is useful when you want to use a custom JavaScript datapicker, which often requires a text type instead of an HTML5 type.

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 (a DateTime 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.

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.

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.

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 three select inputs. The order of the selects is defined in the format option.
• text: renders a three field input of type text (month, day, year).
• single_text: renders a single input of type date. User’s input is validated based on the format option.

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.

by_reference¶

default: false

The DateTime classes are treated as immutable objects.

error_bubbling¶

default: false

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:

$builder->add('token', 'hidden', array(
    'data' => 'abcdef',
));

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:

public function configureOptions(OptionsResolver $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¶

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:

$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.
