Twig Template Form Function Reference

This reference manual covers all the possible Twig functions available for rendering forms. There are several different functions available, and each is responsible for rendering a different part of a form (e.g. labels, errors, widgets, etc).

form_label(, label, variables)

Renders the label for the given field. You can optionally pass the specific label you want to display as the second argument.

{{ form_label( }}

{# The two following syntaxes are equivalent #}
{{ form_label(, 'Your Name', { 'attr': {'class': 'foo'} }) }}
{{ form_label(, null, { 'label': 'Your name', 'attr': {'class': 'foo'} }) }}


Renders any errors for the given field.

{{ form_errors( }}

{# render any "global" errors #}
{{ form_errors(form) }}

form_widget(, variables)

Renders the HTML widget of a given field. If you apply this to an entire form or collection of fields, each underlying form row will be rendered.

{# render a widget, but add a "foo" class to it #}
{{ form_widget(, { 'attr': {'class': 'foo'} }) }}

The second argument to form_widget is an array of variables. The most common variable is attr, which is an array of HTML attributes to apply to the HTML widget. In some cases, certain types also have other template-related options that can be passed. These are discussed on a type-by-type basis.

form_row(, variables)

Renders the “row” of a given field, which is the combination of the field’s label, errors and widget.

{# render a field row, but display a label with text "foo" #}
{{ form_row(, { 'label': 'foo' }) }}

The second argument to form_row is an array of variables. The templates provided in Symfony only allow to override the label as shown in the example above.

form_rest(form, variables)

This renders all fields that have not yet been rendered for the given form. It’s a good idea to always have this somewhere inside your form as it’ll render hidden fields for you and make any fields you forgot to render more obvious (since it’ll render the field for you).

{{ form_rest(form) }}


If the form contains at least one file upload field, this will render the required enctype="multipart/form-data" form attribute. It’s always a good idea to include this in your form tag:

<form action="{{ path('form_submit') }}" method="post" {{ form_enctype(form) }}>
