/**
|
|
* 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.
|
|
*
|
|
* # 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/sapphire/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');
|
|
*
|
|
* # Validation
|
|
*
|
|
* Caution: JavaScript validation is only supported for the 'en_NZ' locale at the moment,
|
|
* it will be disabled automatically for all other locales.
|
