ใช้ datepicker แต่เวลาบันทึกลง database มันกลับขึ้น 0000-00-00 ค่ะ

<script type="text/javascript">
$(function(){
        $("#stopdate,#startdate").datepicker({minDate: 0});
 
  });


});
</script>

$banner = $_FILES['banner']['name'];
list($file_name,$ext_name) = split("\.",$banner) ;
$banner_name  =  time().".".$ext_name ;
//$_SESSION["banner_name"] = "old_name = ". $banner ." banner_name =".$banner_name . " file_name = ".$file_name . " ext = " . $ext_name . "Type = " . $_FILES['banner']['type'] ;
$url = $_POST["url_web"];
$position = $_POST["slcposition"];
$startdate = $_POST["startdate"];
$stopdate = $_POST["stopdate"];


$sql_add_banner = "insert into tblbanner (banner,url,position,start_date,stop_date) " ;
$sql_add_banner .= "values ('$banner_name','$url','$position','$startdate','$stopdate')" ;
