• jquery
• jquery-ui
• jquery-ui-datepicker

• 1 Can you include the PHP script where you get the variable ? are you casting to another type in PHP ? – Manse Commented Nov 2, 2011 at 10:29
• Following is the my PHP code $sdate = showDate($_POST['from_date'],'Y-m-d'); – Hardik Raval Commented Nov 2, 2011 at 10:32
• and the showDate() function ? – Manse Commented Nov 2, 2011 at 10:33
• my guess is that when using showDate or other date functions in PHP if the input is empty of null then the date that is created is epoch (ie 1970-01-01) – Manse Commented Nov 2, 2011 at 10:34
• 1 @Matteo - that wont work if the user can select that date .... – Manse Commented Nov 2, 2011 at 10:43

Change your PHP function is use empty instead of null

function showDate($date,$format='m-d-y, h:i a') {
   if(empty($date)) return ' ';
   return date($format,strtotime($date)); 
}

try to set defaultDate: '' or remove it at all

As you can find in jquery ui documentation (here), if you don't precise defaultDate option, default date is current date.
