    $conn = mysql_connect("localhost","root","123");/*数据库*/
    mysql_query("set names GB2312");
    $db = mysql_select_db("miaolaor");
    $sql="SELECT * FROM  news_listing where news_Id='$_GET[AId]'";
    $query=mysql_query($sql);
    if($_POST['Submit'])
    $sql="update news_listing set news_headline='$_POST[news_headline]',news_intro='$_POST[news_intro]',content='$_POST[content]' where news_Id='$_POST[AId]'";
   //$sql = 'UPDATE `news_listing` SET `news_headline` = \'$news_headline\', `news_intro` = \'$news_intro\', `content` = \'$content\' WHERE `news_listing`.`news_Id` = \'$news_Id\' ;';
   mysql_query($sql);//执行sql语句
    if($sql){
        echo "修改成功";
        echo "返回";
    }else{
        echo "修改失败";
        echo "返回";
    }
    //echo $sql;
   ?>


回复讨论(解决方案)

mysql_query($sql)  or die(mysql_error());//执行sql语句

把SQL 语句放到数据库执行就知道了

改成
if(isset($_POST["submit"])  
试试

提示什么错误了吗?把报错信息贴出来

已经弄好了  谢谢!
