Поле MoneyType¶

currency¶

тип: string по умолчанию: EUR

Указывает валюту, в которой были указаны деньги. Определяет символ валюты, который должен быть отображён возле текстового поля. В зависимости от валюты - символ валюты может быть отображён до или после текстового поля ввода.

Это может быть любой `3-буквенный код ISO 4217`_. Вы также можете установить опцию, как "false", чтобы скрыть символ валюты.

divisor¶

тип: integer по умолчанию: 1

Если, по какой-то причине, вам нужно поделить ваше начальное значение на число, до того, как отображать его пользователю, вы можете использовать опцию divisor. Например:

1
2
3
4
5
6

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

$builder->add('price', MoneyType::class, array(
    'divisor' => 100,
));

В этом случае, если поле price установлено, как 9900, то значение 99 будет автоматически отображено пользователю. Когда пользователь отправляет значение 99, оно будет умножено на 100 и 9900 будет установлено в вашем объектк.

grouping¶

type: integer default: false

This value is used internally as the NumberFormatter::GROUPING_USED value when using PHP's NumberFormatter class. Its documentation is non-existent, but it appears that if you set this to true, numbers will be grouped with a comma or period (depending on your locale): 12345.123 would display as 12,345.123.

scale¶

тип: integer по умолчанию: 2

Если, по какой-то причине, вам нужна какая-то шкала, кроме 2 десятичных разрядов, вы можете изменить это значение. Вам скорее всего не понадобится это делать, разве что, к примеру, вы не захотите округлять до ближайшего доллара(установите шкалу, как 0).

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¶

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:

1
2
3
4
5
6

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

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

empty_data¶

type: mixed

Значение по умолчанию - '' (пустая строка).

This option determines what value the field will return when the submitted value is empty (or missing). It does not set an initial value if none is provided when the form is rendered in a view.

This means it helps you handling form submission with blank fields. For example, if you want the name field to be explicitly set to John Doe when no value is selected, you can do it like this:

1
2
3
4

$builder->add('name', null, array(
    'required'   => false,
    'empty_data' => 'John Doe',
));

This will still render an empty text box, but upon submission the John Doe value will be set. Use the data or placeholder options to show this initial value in the rendered form.

If a form is compound, you can set empty_data as an array, object or closure. See the How to Configure empty Data for a Form Class article for more details about these options.

error_bubbling¶

type: boolean default: false unless the form is compound

If true, any errors for this field will be passed to the parent field or form. For example, if set to true on a normal field, any errors for that field will be attached to the main form, not to the specific field.

error_mapping¶

type: array default: array()

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 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 right side contains simply 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:

1
2
3
4
5

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

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).

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', SomeFormType::class, array(
    // ...
    'invalid_message' => 'You entered an invalid value, it should include %num% letters',
    'invalid_message_parameters' => array('%num%' => 6),
));

label¶

type: string default: The label is "guessed" from the field name

Sets the label that will be used when rendering the field. Setting to false will suppress the label. The label can also be directly set inside the template:

label_attr¶

type: array default: array()

Sets the HTML attributes for the <label> element, which will be used when rendering the label for the field. It's an associative array with HTML attribute as a key. This attributes can also be directly set inside the template:

label_format¶

type: string default: null

Configures the string used as the label of the field, in case the label option was not set. This is useful when using keyword translation messages.

If you're using keyword translation messages as labels, you often end up having multiple keyword messages for the same label (e.g. profile_address_street, invoice_address_street). This is because the label is build for each "path" to a field. To avoid duplicated keyword messages, you can configure the label format to a static value, like:

1
2
3
4
5
6
7
8

// ...
$profileFormBuilder->add('address', AddressType::class, array(
    'label_format' => 'form.address.%name%',
));

$invoiceFormBuilder->add('invoice', AddressType::class, array(
    'label_format' => 'form.address.%name%',
));

This option is inherited by the child types. With the code above, the label of the street field of both forms will use the form.address.street keyword message.

Two variables are available in the label format:

%id%

A unique identifier for the field, consisting of the complete path to the field and the field name (e.g. profile_address_street);

%name%

The field name (e.g. street).

The default value (null) results in a "humanized" version of the field name.

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.

required¶

type: boolean default: true

If true, an HTML5 required attribute will be rendered. The corresponding label will also render with a required class.

This is superficial and independent from validation. At best, if you let Symfony guess your field type, then the value of this option will be guessed from your validation information.
