I need to hire a developer who can make the following customization to jQuery’s date picker ([login to view URL]):
• Date should be of the format DD-MMM-YYYY
• Date picker needs to be able to accept 'UNK' for either the day or month or year or any combination of the three
o Ex: 13-Feb-2013
o Ex: UNK-Feb-2012
o Ex: 13-UNK-2013
o Ex: 12-Feb-UNK
o Ex: UNK-UNK-2013
I would also like a PHP regular expression/function that would validate this date format.
If you have any questions please don’t hesitate to let me know.
