php createFromFormat fails with datepicker -

i have below datepicker in form:

$( '.datepicker' ).datepicker({ dateformat: 'dd-mm-yy' }); 

then in php code processes form have:

$campaigndate = datetime::createfromformat('d-m-y', $formdata['campaign']['campaign_date']         );          if ($campaigndate) {             $campaignunixdate = $campaigndate->gettimestamp();         } else {             $response = array(                 'status' => 'failed',                 'message' => 'failed create campaign date',                 'redirect' => ''             );             echo json_encode($response);             return;         } 

$campaigndate seems false, assume have wrong format createfrom cant work out issue.

solution

use uppercase y instead of lowercase y

$campaigndate = datetime::createfromformat(    'd-m-y',     $formdata['campaign']['campaign_date'] ); 

explanation

the date formats don't match

$( '.datepicker' ).datepicker({ dateformat: 'dd-mm-yy' }); 

would return

18-07-2015

while

$campaigndate = datetime::createfromformat(    'd-m-y',     $formdata['campaign']['campaign_date'] ); 

uses format

18-07-15

from php docs:

y
full numeric representation of year, 4 digits
examples: 1999 or 2003

y
2 digit representation of year (which assumed in range 1970-2069, inclusive) examples: 99 or 03 (which interpreted 1999 , 2003, respectively)
