//echo $rr;
$er=mysql_query("select * from 013client where client_id='$app_id'");
$re=mysql_fetch_array($er);

$tr=mysql_query("insert into print_details values('',$prd_type,$prd_id,'$app_id','cash','$branch','$recpt_no','$dt_by','$date','renewal')");

If you get 0000-00-00 it means it was either not set, or invalid. You'll have to make sure the format is 'yyyy-mm-dd'

[mastermind2]

insert into 018renewal values('',2,25,'100404','2013-2-30',300,'paid','2013-2-30','HEAD_OFFICE',5)

check this i think it is
