Description
bootstrap_3_layout.html.twig, bootstrap_3_horizontal_layout.html.twig and foundation_5_layout.html.twig do not support help message for checkbox field ;
Originally reported in #29135 but closed due to lack of feedback.
How to reproduce
Standalone Controller: src/Controller/DefaultController.php
<?php declare(strict_types=1);
namespace App\Controller;
use Symfony\Component\Form\Extension\Core\Type\CheckboxType;
use Symfony\Component\HttpFoundation\Response;
use Symfony\Component\Routing\Annotation\Route;
class DefaultController extends AbstractController
{
/**
* @Route(methods={"GET"})
*/
public function index(): Response
{
$form = $this
->createFormBuilder()
->add('isChecked', CheckboxType::class, ['help' => 'foo'])
->getForm();
return $this->render('foo.html.twig', [
'form' => $form->createView(),
]);
}
}Template: templates/foo.html.twig
{#
form_div_layout.html.twig
form_table_layout.html.twig
bootstrap_3_layout.html.twig
bootstrap_3_horizontal_layout.html.twig
bootstrap_4_layout.html.twig
bootstrap_4_horizontal_layout.html.twig
foundation_5_layout.html.twig
#}
<h1>bootstrap_3_layout.html.twig</h1>
{% form_theme form 'bootstrap_3_layout.html.twig' %}
{{ form(form) }}
Possible Solution
form_help is not called in bootstrap_3_layout.html.twig or bootstrap_3_horizontal_layout.html.twig or foundation_5_layout.html.twig in the block checkbox_row.
See bootstrap_3_layout.html.twig here:
{% block checkbox_row -%}
<div{% with {attr: row_attr|merge({class: (row_attr.class|default('') ~ ' form-group' ~ (not valid ? ' has-error'))|trim})} %}{{ block('attributes') }}{% endwith %}>
{{- form_widget(form) -}}
{{- form_errors(form) -}}
</div>
{%- endblock checkbox_row %}You can spot the difference with the same block in bootstrap_4_horizontal_layout.html.twig:
{% block checkbox_row -%}
<div{% with {attr: row_attr|merge({class: (row_attr.class|default('') ~ ' form-group row')|trim})} %}{{ block('attributes') }}{% endwith %}>{#--#}
<div class="{{ block('form_label_class') }}"></div>{#--#}
<div class="{{ block('form_group_class') }}">
{{- form_widget(form) -}}
{{- form_help(form) -}}
</div>{#--#}
</div>
{%- endblock checkbox_row %}It was fixed for bootstrap 4 in 68a9a07.
