Deprecation: #109152 - Form DatePicker element 

Description 

The DatePicker form element type and its associated DatePickerViewHelper and TimePickerViewHelper have been deprecated as part of removing jQuery dependency from typo3/cms-form . The Date form element type serves as a replacement and uses native HTML5 <input type="date"> without needing a JavaScript library.

The following components are deprecated:

• \TYPO3\CMS\Form\Domain\Model\FormElements\DatePicker
• \TYPO3\CMS\Form\ViewHelpers\Form\DatePickerViewHelper
• \TYPO3\CMS\Form\ViewHelpers\Form\TimePickerViewHelper
• The EXT:form/Resources/Public/JavaScript/frontend/date-picker.js jQuery initialization script

Impact 

Using the DatePicker form element type in a form definition will trigger a PHP E_USER_DEPRECATED level error at runtime. The element, its ViewHelpers, and the JavaScript file will be removed in TYPO3 v15.

Affected installations 

All installations that use the DatePicker form element type in form definitions created with the TYPO3 Form Framework.

Migration 

Replace DatePicker with the Date form element type in your form definitions.

Before:

type: DatePicker
identifier: date-1
label: 'Pick a date'
properties:
  dateFormat: Y-m-d
  enableDatePicker: true

After:

type: Date
identifier: date-1
label: 'Pick a date'

The Date element uses a native HTML5 date input, which does not require jQuery or additional JavaScript. The dateFormat and enableDatePicker properties are no longer needed because the browser handles date formatting and the picker natively.

Alternatively, if the native HTML5 date input does not meet your requirements, you can create a custom form element with a date picker JavaScript library of your choice.
