Tip

The full list of options defined and inherited by this form type is available running this command in your app:

# replace 'FooType' by the class name of your form type
$ php bin/console debug:form FooType

Inherited Options

The following options are defined in the BaseType class. The BaseType class is the parent class for both the button type and the FormType, but it is not part of the form type tree (i.e. it cannot be used as a form type on its own).

attr

type: array default: []

If you want to add extra attributes to the HTML representation of the button, you can use attr option. It’s an associative array with HTML attribute as a key. This can be useful when you need to set a custom class for the button:

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

$builder->add('save', ButtonType::class, [
    'attr' => ['class' => 'save'],
]);

disabled

type: boolean default: false

If you don’t want a user to be able to click a button, you can set the disabled option to true. It will not be possible to submit the form with this button, not even when bypassing the browser and sending a request manually, for example with cURL.

label

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

Sets the label that will be displayed on the button. The label can also be directly set inside the template:

• Twig

  {{ form_widget(form.save, { 'label': 'Click me' }) }}
  

• PHP

  <?= $view['form']->widget($form['save'], ['label' => 'Click me']) ?>
  

label_html

type: bool default: false

New in version 5.1: The label_html option was introduced in Symfony 5.1.

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

translation_domain

type: string default: messages

This is the translation domain that will be used for any labels or options that are rendered for this button.

label_translation_parameters

type: array default: []

The content of the label option is translated before displaying it, so it can contain translation placeholders. This option defines the values used to replace those placeholders.

Given this translation message:

# translations/messages.en.yaml
form.order.submit_to_company: 'Send an order to %company%'

You can specify the placeholder values as follows:

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

$builder->add('send', ButtonType::class, [
    'label' => 'form.order.submit_to_company',
    'label_translation_parameters' => [
        '%company%' => 'ACME Inc.',
    ],
]);

The label_translation_parameters option of buttons is merged with the same option of its parents, so buttons can reuse and/or override any of the parent placeholders.

attr_translation_parameters

type: array default: []

The content of the title and placeholder values defined in the attr option is translated before displaying it, so it can contain translation placeholders. This option defines the values used to replace those placeholders.

Given this translation message:

# translations/messages.en.yaml
form.order.id.placeholder: 'Enter unique identifier of the order to %company%'
form.order.id.title: 'This will be the reference in communications with %company%'

You can specify the placeholder values as follows:

$builder->add('id', null, [
    'attr' => [
        'placeholder' => 'form.order.id.placeholder',
        'title' => 'form.order.id.title',
    ],
    'attr_translation_parameters' => [
        '%company%' => 'ACME Inc.',
    ],
]);

The attr_translation_parameters option of children fields is merged with the same option of their parents, so children can reuse and/or override any of the parent placeholders.

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' => '...'],
]);
