这个delete删除 哪里异常了

这个delete删除 哪里错误了？

 
 




$con = @mysql_connect("localhost","root","")or die("failed to connect the database");
mysql_select_db("iccp",$con);
mysql_query("set names 'GBK'");
$sql="select * from t_paper where contributor_id=118";
$query = mysql_query($sql);
while($row=mysql_fetch_array($query)){
?>

	Paper Title	Comments	Upload Date	Delete
	=@$row['paper_title']?>		=@$row['upload_time']?>

}
if(!empty($_POST['name'])){
$str = explode(",",$_POST['name']);
  mysql_query("delete from t_paper where paper_title in($str)");}
?>


这里测试 为什么无法得到$_POST['name']的值

------解决方案--------------------
form 表单都没

------解决方案--------------------
另外，判断表单是否被提交应该用isset()

PHP code

if (isset($_POST['name'])) {    $str = explode(",",$_POST['name']);    mysql_query("delete from t_paper where paper_title in($str)"); //这里明显有问题，explode()函数返回的是一个数组，SQL语句语法错误了}<div class="clear">
                 
              
              
        
            </div>
