.. index:: single: Forms; Fields; RadioType RadioType Field =============== Creates a single radio button. If the radio button is selected, the field will be set to the specified value. Radio buttons cannot be unchecked - the value only changes when another radio button with the same name gets checked. The ``RadioType`` isn't usually used directly. More commonly it's used internally by other types such as :doc:`ChoiceType `. If you want to have a boolean field, use :doc:`CheckboxType `. +-------------+---------------------------------------------------------------------+ | Rendered as | ``input`` ``radio`` field | +-------------+---------------------------------------------------------------------+ | Inherited | from the :doc:`CheckboxType `: | | options | | | | - `value`_ | | | | | | from the :doc:`FormType `: | | | | | | - `attr`_ | | | - `data`_ | | | - `disabled`_ | | | - `empty_data`_ | | | - `error_bubbling`_ | | | - `error_mapping`_ | | | - `help`_ | | | - `help_attr`_ | | | - `help_html`_ | | | - `label`_ | | | - `label_attr`_ | | | - `label_format`_ | | | - `mapped`_ | | | - `required`_ | | | - `row_attr`_ | +-------------+---------------------------------------------------------------------+ | Parent type | :doc:`CheckboxType ` | +-------------+---------------------------------------------------------------------+ | Class | :class:`Symfony\\Component\\Form\\Extension\\Core\\Type\\RadioType` | +-------------+---------------------------------------------------------------------+ .. include:: /reference/forms/types/options/_debug_form.rst.inc Inherited Options ----------------- These options inherit from the :doc:`CheckboxType `: .. include:: /reference/forms/types/options/value.rst.inc These options inherit from the :doc:`FormType `: .. include:: /reference/forms/types/options/attr.rst.inc .. include:: /reference/forms/types/options/data.rst.inc .. include:: /reference/forms/types/options/disabled.rst.inc .. include:: /reference/forms/types/options/checkbox_empty_data.rst.inc .. include:: /reference/forms/types/options/error_bubbling.rst.inc .. include:: /reference/forms/types/options/error_mapping.rst.inc .. include:: /reference/forms/types/options/help.rst.inc .. include:: /reference/forms/types/options/help_attr.rst.inc .. include:: /reference/forms/types/options/help_html.rst.inc .. include:: /reference/forms/types/options/label.rst.inc .. include:: /reference/forms/types/options/label_attr.rst.inc .. include:: /reference/forms/types/options/label_format.rst.inc .. include:: /reference/forms/types/options/mapped.rst.inc .. include:: /reference/forms/types/options/required.rst.inc .. include:: /reference/forms/types/options/row_attr.rst.inc Form Variables -------------- .. include:: /reference/forms/types/variables/check_or_radio_table.rst.inc
