Any submitted value will be ignored. This option determines what value the field will return when the submitted value is empty or missing. It does not set an initial value if none is provided when the form is rendered in a view.

This means it helps you handling form submission with blank fields. Use the data or placeholder options to show this initial value in the rendered form. This means that an empty string will be cast to null.

Use a custom data transformer if you explicitly want to return the empty string. For example, if set to true on a normal field, any errors for that field will be attached to the main form, not to the specific field.

Imagine you have a custom method named matchingCityAndZipCode that validates whether the city and zip code match. Unfortunately, there is no matchingCityAndZipCode field in your form, so all that Symfony can do is display the error on top of the form. For example: addresses[work]. By default, errors for any property that is not mapped will bubble up to the parent form.

You can use the dot. Its value is an associative array with HTML attribute names as keys. Set this option to true to not escape them, which is useful when the help contains HTML elements. Setting to false will suppress the label. The label can also be directly set inside the template: Twig.
