percent Field Type

The percent type renders an input text field and specializes in handling percentage data. If your percentage data is stored as a decimal (e.g. .95), you can use this field out-of-the-box. If you store your data as a number (e.g. 95), you should set the type option to integer.

This field adds a percentage sign "%" after the input box.

type: string default: fractional

This controls how your data is stored on your object. For example, a percentage corresponding to "55%", might be stored as .55 or 55 on your object. The two "types" handle these two cases:

  • fractional If your data is stored as a decimal (e.g. .55), use this type. The data will be multiplied by 100 before being shown to the user (e.g. 55). The submitted data will be divided by 100 on form submit so that the decimal value is stored (.55);
  • integer If your data is stored as an integer (e.g. 55), then use this option. The raw value (55) is shown to the user and stored on your object. Note that this only works for integer values.


type: integer default: 0

By default, the input numbers are rounded. To allow for more decimal places, use this option.

Inherited Options

These options inherit from the field type:


type: Boolean default: true

If true, an HTML5 required attribute will be rendered. The corresponding label will also render with a required class.

This is superficial and independent from validation. At best, if you let Symfony guess your field type, then the value of this option will be guessed from your validation information.


type: string default: The label is "guessed" from the field name

Sets the label that will be used when rendering the field. The label can also be directly set inside the template:

{{ form_label(, 'Your name') }}


type: Boolean default: false

If this option is true, the field will be rendered with the disabled attribute so that the field is not editable.


type: Boolean default: false

If true, any errors for this field will be passed to the parent field or form. 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.


type: string default: This value is not valid

This is the validation error message that's used if the data entered into this field doesn't make sense (i.e. fails validation).

This might happen, for example, if the user enters a nonsense string into a time field that cannot be converted into a real time or if the user enters a string (e.g. apple) into a number field.

Normal (business logic) validation (such as when setting a minimum length for a field) should be set using validation messages with your validation rules (reference).


type: array default: array()

When setting the invalid_message option, you may need to include some variables in the string. This can be done by adding placeholders to that option and including the variables in this option:

$builder->add('some_field', 'some_type', array(
    // ...
    'invalid_message'            => 'You entered an invalid value - it should include %num% letters',
    'invalid_message_parameters' => array('%num%' => 6),
