Поле DateType¶

Отображение одного текстового поля HTML5¶

Для лучшего опыта использования, вы можете захотеть отобразить одно текстовое поле и использовать какой-то “определитель даты”, чтобы помочь вашему пользователю заполнить в правильном формате. Чтобы сделать это, используйте виджет single_text:

use Symfony\Component\Form\Extension\Core\Type\DateType;
// ...

$builder->add('publishedAt', DateType::class, [
    // renders it as a single text box
    'widget' => 'single_text',
]);

Это отобразится в виде HTML5-поля input type="date", что означает, что некоторые, но не все, браузеры будут добавлять к полю удобную функциональность определителя даты. Если вы хотите быть абсолютно уверены, что каждый пользовать имеет работающий определитель даты, используйте внешнюю библиотеку JavaScript.

Например, представьте, что вы хотите использовать библиотеку Bootstrap Datepicker. Для начала, сделайте следующие изменения:

use Symfony\Component\Form\Extension\Core\Type\DateType;
// ...

$builder->add('publishedAt', DateType::class, [
    'widget' => 'single_text',

    // предотвращает его отображение как type="date", чтобы избежать определителей даты HTML5
    'html5' => false,

    // добавляет класс, который может быть выбран в JavaScript
    'attr' => ['class' => 'js-datepicker'],
]);

Далее, добавьте следующий код JavaScript в ваш шаблон, чтобы инициализировать избиратель даты:

1
2
3
4
5
6
7
8

<script>
    $(document).ready(function() {
        // вам может понадобиться изменить этот код, если вы не используете Bootstrap Datepicker
        $('.js-datepicker').datepicker({
            format: 'yyyy-mm-dd'
        });
    });
</script>

Этот ключ format сообщает определителю даты, чтобы он использовал формат даты, который ожидает Symfony. Это может быть непросто: если определитель даты сконфигурирован неправильно, то Symfony не поймёт форма и выдаст ошибку валидации. Вы также можете сконфигурировать формат, который будет ожидаться Symfony, через опцию format.

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¶

тип: string | array

Если ваша опция виджета установлена, как choice, то это поле будет представлено, как серия полей выбора select. Когда значение заполнителя - строка, она будет использована, как пустое значене всех полей выбора:

$builder->add('dueDate', DateType::class, [
    'placeholder' => 'Select a value',
]);

Как вариант, вы можете использовать массив, который конфигурирует разные значеня заполнителя для полей года, месяца и дня:

$builder->add('dueDate', DateType::class, [
    'placeholder' => [
        '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:

use Symfony\Component\Form\Extension\Core\Type\DateType;
// ...

$builder->add('dateCreated', DateType::class, [
    '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-local) 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 datepicker, 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)
• datetime_immutable (a DateTimeImmutable object)
• array (e.g. ['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.

input_format¶

type: string default: Y-m-d

If the input option is set to string, this option specifies the format of the date. This must be a valid PHP date 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¶

по умолчанию: false

К классам DateTime относятся, как к неизменяемым объектам.

choice_translation_domain¶

type: string, boolean or null default: false

This option determines if the choice values should be translated and in which translation domain.

The values of the choice_translation_domain option can be true (reuse the current translation domain), false (disable translation), null (uses the parent translation domain or the default domain) or a string which represents the exact translation domain to use.

compound¶

type: boolean default: false

This option specifies whether the type contains child types or not. This option is managed internally for built-in types, so there is no need to configure it explicitly.

data_class¶

type: string default: null

The internal normalized representation of this type is an array, not a \DateTime object. Therefore, the data_class option is initialized to null to avoid the FormType object from initializing it to \DateTime.

error_bubbling¶

по умолчанию: false

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 TimeType 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).

attr¶

type: array default: []

If you want to add extra attributes to an HTML field representation you can use the attr option. It’s an associative array with HTML attributes as keys. This can be useful when you need to set a custom class for some widget:

$builder->add('body', TextareaType::class, [
    'attr' => ['class' => 'tinymce'],
]);

data¶

type: mixed default: Defaults to field of the underlying structure.

When you create a form, each field initially displays the value of the corresponding property of the form’s domain data (e.g. if you bind an object to the form). If you want to override this initial value for the form or an individual field, you can set it in the data option:

use Symfony\Component\Form\Extension\Core\Type\HiddenType;
// ...

$builder->add('token', HiddenType::class, [
    '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: []

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([
        'error_mapping' => [
            '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 the 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 right side contains the names of fields in the form.

By default, errors for any property that is not mapped will bubble up to the parent form. You can use the dot (.) on the left side to map errors of all unmapped properties to a particular field. For instance, to map all these errors to the city field, use:

$resolver->setDefaults([
    'error_mapping' => [
        '.' => 'city',
    ],
]);

help¶

type: string or TranslatableMessage default: null

Allows you to define a help message for the form field, which by default is rendered below the field:

use Symfony\Component\Translation\TranslatableMessage;

$builder
    ->add('zipCode', null, [
        'help' => 'The ZIP/Postal code for your credit card\'s billing address.',
    ])

    // ...

    ->add('status', null, [
        'help' => new TranslatableMessage('order.status', ['%order_id%' => $order->getId()], 'store'),
    ])
;

help_attr¶

type: array default: []

Sets the HTML attributes for the element used to display the help message of the form field. Its value is an associative array with HTML attribute names as keys. These attributes can also be set in the template:

1
2
3

{{ form_help(form.name, 'Your name', {
    'help_attr': {'class': 'CUSTOM_LABEL_CLASS'}
}) }}

help_html¶

type: boolean default: false

By default, the contents of the help option are escaped before rendering them in the template. Set this option to true to not escape them, which is useful when the help contains HTML elements.

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_parameters¶

type: array default: []

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('someField', SomeFormType::class, [
    // ...
    'invalid_message' => 'You entered an invalid value, it should include %num% letters',
    'invalid_message_parameters' => ['%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.

row_attr¶

type: array default: []

An associative array of the HTML attributes added to the element which is used to render the form type row:

$builder->add('body', TextareaType::class, [
    'row_attr' => ['class' => 'text-editor', 'id' => '...'],
]);
