WeekType Field ¶

placeholder ¶

type: string | array

If your widget option is set to choice, then this field will be represented as a series of select boxes. When the placeholder value is a string, it will be used as the blank value of all select boxes:

1
2
3
4
5

use Symfony\Component\Form\Extension\Core\Type\WeekType;

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

Alternatively, you can use an array that configures different placeholder values for the year and week fields:

1
2
3
4
5
6
7
8

use Symfony\Component\Form\Extension\Core\Type\WeekType;

$builder->add('startDateTime', WeekType::class, [
    'placeholder' => [
        'year' => 'Year',
        'week' => 'Week',
    ],
]);

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: array

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-W17")
  文字列 (例: "2011-W17")
• array (e.g. [2011, 17])
  配列 (例: [2011, 17])

The value that comes back from the form will also be normalized back into this format.

widget ¶

type: string default: choice

The basic way in which this field should be rendered. Can be one of the following:

• choice: renders two select inputs;
  選択: 2 つの選択入力をレンダリングします。
• text: renders a two field input of type text (year and week);
  text: テキスト型 (年と週) の 2 つのフィールド入力をレンダリングします。
• single_text: renders a single input of type week.
  single_text: 週型の単一の入力をレンダリングします。

years ¶

type: array default: ten years before to ten 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.

weeks ¶

type: array default: 1 to 53

List of weeks available to the week field type. This option is only relevant when the widget option is set to choice.

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.

empty_data ¶

type: mixed

The actual default value of this option depends on other field options:

• If widget is single_text, then '' (empty string);
  widget が single_text の場合、'' (空の文字列);
• Otherwise [] (empty array).
  それ以外の場合は [] (空の配列)。

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, [
    '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 ¶

default: 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:

1
2
3

$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:

1
2
3
4
5
6

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.

help ¶

type: string or TranslatableInterface default: null

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

1
2
3
4
5
6
7
8
9
10
11
12
13

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:

1
2
3
4
5

$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:

1
2
3

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