.. index:: single: Forms; Fields; TelType TelType Field =============== The ``TelType`` field is a text field that is rendered using the HTML5 ```` tag. Following the recommended HTML5 behavior, the value of this type is not validated in any way, because formats for telephone numbers vary too much depending on each country. Nevertheless, it may be useful to use this type in web applications because some browsers (e.g. smartphone browsers) adapt the input keyboard to make it easier to input phone numbers. +-------------+---------------------------------------------------------------------+ | Rendered as | ``input`` ``tel`` field (a text box) | +-------------+---------------------------------------------------------------------+ | Inherited | - `attr`_ | | options | - `data`_ | | | - `disabled`_ | | | - `empty_data`_ | | | - `error_bubbling`_ | | | - `error_mapping`_ | | | - `help`_ | | | - `help_attr`_ | | | - `help_html`_ | | | - `label`_ | | | - `label_attr`_ | | | - `label_format`_ | | | - `mapped`_ | | | - `required`_ | | | - `row_attr`_ | | | - `trim`_ | +-------------+---------------------------------------------------------------------+ | Parent type | :doc:`TextType ` | +-------------+---------------------------------------------------------------------+ | Class | :class:`Symfony\\Component\\Form\\Extension\\Core\\Type\\TelType` | +-------------+---------------------------------------------------------------------+ .. include:: /reference/forms/types/options/_debug_form.rst.inc Inherited Options ----------------- 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/empty_data.rst.inc :end-before: DEFAULT_PLACEHOLDER The default value is ``''`` (the empty string). .. include:: /reference/forms/types/options/empty_data.rst.inc :start-after: DEFAULT_PLACEHOLDER .. 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 .. include:: /reference/forms/types/options/trim.rst.inc
