url Field Type¶

The url field is a text field that prepends the submitted value with a given protocol (e.g. http://) if the submitted value doesn’t already have a protocol.

Rendered as	`input url` field
Options	default_protocol
Inherited options	max_length required label trim read_only error_bubbling
Parent type	text
Class	`Symfony\Component\Form\Extension\Core\Type\UrlType`

Field Options¶

default_protocol¶

type: string default: http

If a value is submitted that doesn’t begin with some protocol (e.g. http://, ftp://, etc), this protocol will be prepended to the string when the data is bound to the form.

Inherited Options¶

These options inherit from the field type:

max_length¶

type: integer

This option is used to add a max_length attribute, which is used by some browsers to limit the amount of text in a field.

required¶

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.

label¶

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(form.name, 'Your name') }}

trim¶

type: Boolean default: true

If true, the whitespace of the submitted string value will be stripped via the trim() function when the data is bound. This guarantees that if a value is submitted with extra whitespace, it will be removed before the value is merged back onto the underlying object.

read_only¶

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.

error_bubbling¶

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.
