On IE8, camel case element attributes are NOT included in the object returned by $(elem).data(), meaning attrs defined in DateField.php (jqueryDateformat and isoDateformat) are NOT seen by the code in DateField.js (ie the "config" var doesn't have these set). Causing IE8 to fall back to using US date (mm/dd/yyyy) formats. This can subsequently cause validation issues if the user's date format is different. DateField.js already explicitly checks for jquerydateformat (all lowercase) so DateField.php has been modified to reflect the correct case for this attribute name

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