button Field Type¶

2.3 新版功能: The button type was introduced in Symfony 2.3

A simple, non-responsive button.

Rendered as	`button` tag
Inherited options	attr disabled label translation_domain
Parent type	none
Class	`ButtonType`

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 form type, but it is not part of the form type tree (i.e. it can not be used as a form type on its own).

attr¶

type: array default: Empty array

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:

$builder->add('save', 'button', array(
    'attr' => array('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

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

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.
