SubmitType Field ¶

validate ¶

type: boolean default: true

Set this option to false to disable the client-side validation of the form performed by the browser.

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:

1
2
3
4
5
6

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

$builder->add('save', SubmitType::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:

1

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

1

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

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 built 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, [
    'label_format' => 'form.address.%name%',
]);

$invoiceFormBuilder->add('invoice', AddressType::class, [
    '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);

フィールドへの完全なパスとフィールド名 (例: profile_address_street) で構成される、フィールドの一意の識別子。

%name%

The field name (e.g. street).

フィールド名 (通りなど)。

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

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:

1
2

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

You can specify the placeholder values as follows:

1
2
3
4
5
6
7
8
9

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

$builder->add('send', SubmitType::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:

1
2
3

# 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:

1
2
3
4
5
6
7
8
9

$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:

1
2
3

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

validation_groups ¶

type: array default: null

When your form contains multiple submit buttons, you can change the validation group based on the button which was used to submit the form. Imagine a registration form wizard with buttons to go to the previous or the next step:

1
2
3
4
5
6
7
8
9
10
11

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

$form = $this->createFormBuilder($user)
    ->add('previousStep', SubmitType::class, [
        'validation_groups' => false,
    ])
    ->add('nextStep', SubmitType::class, [
        'validation_groups' => ['Registration'],
    ])
    ->getForm();

The special false ensures that no validation is performed when the previous step button is clicked. When the second button is clicked, all constraints from the "Registration" are validated.
