错误PHP更新Mysql行

what wrong with my PHP MySQL Update ?
this my php code :

<?
if(isset($_POST['update_judulanime'])){
$jdl_nime = trim($_POST['JDLAN']);
$setID = $_GET['nime_id'];
$queryUPJDL = "UPDATE `anime_completed` SET `judul_anime` = '$jdl_nime' WHERE `anime_completed`.`nime_id` = '".$setID."'";
$exUPJDL = mysql_query($queryUPJDL);
if($exUPJDL){
   echo "Success update Judul Anime";
}else{
   echo "Error Update".mysql_error();
}
?>

if i push this button, it doesn't execute that query this my html button code :

<button type="submit" name="update_judulanime">Update Title</button>

it just loading but doesn't update the row.. no error reports

Try this.. !!

    <?
    if(isset($_POST['update_judulanime'])){
    $jdl_nime = trim($_POST['JDLAN']);
    $setID = $_GET['nime_id'];
    $queryUPJDL = "UPDATE `anime_completed` SET `judul_anime` = '$jdl_nime' WHERE `anime_completed`.`nime_id` = '".$setID."'";
    $exUPJDL = mysql_query($queryUPJDL);
    if($exUPJDL){
       echo "Success update Judul Anime";
    }else{
       echo "Error Update".mysql_error();
    }
}
    ?>

You Haven't Closed if(isset($_POST['update_judulanime'])) { braces. So it will be showing empty screen or no errors.

Hope this helps.
