silverstripe-framework/Forms/DateField.php
Ingo Schommer 8f23fa99a5 API Moved CMS-specific JavaScript to admin/thirdparty
The 'admin' module will be split off from 'framework',
where 'framework' only provides (mostly) frontend-agnostic PHP classes.
For example, HTMLEditorField.php has a TinyMCEConfig.php driver,
but doesn't come with its own JS includes.

/**
* Form field to display an editable date string,
* either in a single `<input type="text">` field,
* or in three separate fields for day, month and year.
*
* # Configuration
*
* - 'showcalendar' (boolean): Determines if a calendar picker is shown.
* By default, jQuery UI datepicker is used (see {@link DateField_View_JQuery}).
* - 'jslocale' (string): Overwrites the "Locale" value set in this class.
* Only useful in combination with {@link DateField_View_JQuery}.
* - 'dmyfields' (boolean): Show three input fields for day, month and year separately.
* CAUTION: Might not be useable in combination with 'showcalendar', depending on the used javascript library
* - 'dmyseparator' (string): HTML markup to separate day, month and year fields.
* Only applicable with 'dmyfields'=TRUE. Use 'dateformat' to influence date representation with 'dmyfields'=FALSE.
* - 'dmyplaceholders': Show HTML5 placehoder text to allow identification of the three separate input fields
* - 'dateformat' (string): Date format compatible with Zend_Date.
* Usually set to default format for {@link locale} through {@link Zend_Locale_Format::getDateFormat()}.
* - 'datavalueformat' (string): Internal ISO format string used by {@link dataValue()} to save the
* date to a database.
* - 'min' (string): Minimum allowed date value (in ISO format, or strtotime() compatible).
* Example: '2010-03-31', or '-7 days'
* - 'max' (string): Maximum allowed date value (in ISO format, or strtotime() compatible).
* Example: '2010-03-31', or '1 year'
*
* Depending which UI helper is used, further namespaced configuration options are available.
* For the default jQuery UI, all options prefixed/namespaced with "jQueryUI." will be respected as well.
* Example: <code>$myDateField->setConfig('jQueryUI.showWeek', true);</code>
* See http://docs.jquery.com/UI/Datepicker for details.
*
* Caution: The form field does not include any JavaScript or CSS when used outside of the CMS context,
* since the required frontend dependencies are included through CMS bundling.
*
* # Localization
*
* The field will get its default locale from {@link i18n::get_locale()}, and set the `dateformat`
* configuration accordingly. Changing the locale through {@link setLocale()} will not update the
* `dateformat` configuration automatically.
*
* See http://doc.silverstripe.org/framework/en/topics/i18n for more information about localizing form fields.
*
* # Usage
*
* ## Example: German dates with separate fields for day, month, year
*
* $f = new DateField('MyDate');
* $f->setLocale('de_DE');
* $f->setConfig('dmyfields', true);
*
* # Validation
*
* Caution: JavaScript validation is only supported for the 'en_NZ' locale at the moment,
* it will be disabled automatically for all other locales.
