Adding "help" messages to fields

Question

I'm trying to add some help messages after each field in form in symfony2.

I have read about one solution in official docs : http://symfony.com/doc/current/cookbook/form/form_customization.html#adding-help-messages

But this solution makes little sense, because we've need to create all form manually. For example, it easy to define label: $formBuilder->add('myfieldname', 'text', array('label'=>'some my field label')); But how to pass help messages? (In other words, some custom variables)

Answer 1

A another method without another extension :

In your form builder class:

$builder->add('yourField',null, array('attr'=>array('help'=>'text help'))) 

In your form template rewrite:

{% block form_row %}     {% spaceless %}             {{ form_label(form) }}                 {{ form_widget(form) }}                 {% for attrname, attrvalue in attr %}                     {% if attrname == 'help' %}                         <span class="help-block">{{ attrvalue }}</span>                     {% endif %}                 {% endfor %}             {{ form_errors(form) }}     {% endspaceless %} {% endblock form_row %} 

Answer 2

$formBuilder->add('myFieldName', 'text', array('help' => 'My Help Message')); But it think you also need to add an extension that add this as a default option for all forms :

This makes you able to edit attributes directly from you FormTypes.

Since symfony 4.1 you can do :

$builder->add('email', null, [
    'help' => 'Make sure to add a valid email',
]);
