怎么就删不掉呢!!!!

$F1 = $_POST['F1'];
       
$res = mysql_query("delete from photography where F1='$F1'");
               
     if($res)
{
             echo "$F1<br><p>The selected items were successfully deleted.</p>";
}
    else
{
             echo "<p>There was a problem deleting some of the selected items.</p>";
}


运行后显示:The selected items were successfully deleted.

但数据还在

解决了
