Datepicker in symfony with i18n
Some time ago we decided in Makoondi that would be better to have one of these jquery calendars where the user picks the date:

The first version was easy to implement with sfFormExtraPlugin , that implements sfWidgetFormJQueryDate.
$this->setWidget('available_from', new sfWidgetFormJQueryDate(array(
'image'=>'/images/icons/calendar.gif',
'culture' => sfContext::getInstance()->getUser()->getCulture(),
'format' => '%day%/%month%/%year%')
));
You will need, apart from the plugin, some jquery files that you can download from the jquery-ui website:
jquery-ui-1.7.2.custom.min.js
jquery.datePicker.js
and, in order to use the i18n, you will need the localized version of jpicker from this website. e. g. the file with translations to Spanish would be:
jquery.datepick-es.js
But be aware! you will need to change mentions to $.datepick to $datepicker in that file in order to get it working!
$.datepicker.regional['es'] = {
...
$.datepicker.setDefaults($.datepicker.regional['es']);
otherwise you will get a ”$.datepick is undefined” error :(
