Php mysql-从表行获取数据

我得到了一段代码，可以返回用户名和密码，看看它们是否匹配。现在，我想将会话变量设置为表中的“points”值，该值与用户名和pass位于同一行。。可以做些什么

    <?php $username="asdin";
$password="1sdA2";
$database="a75sdting";
$pword = $_REQUEST['pword'];
$uname = $_REQUEST['uname'];
mysql_connect('mysqsdst.com',$username,$password);
@mysql_select_db($database) or die( "Unable to select database");
$query = mysql_query("SELECT * FROM `username` WHERE `password` = '$pword' AND `username` = '$uname'");
$exsists = 0;

        WHILE($rows = mysql_fetch_array($query)){
         $exsists = 1;
         break;
         }
            if ($exsists){
            $_SESSION['usern']=$uname;
            $_SESSION['logged']=1;

            header('Location: http://wwsdipts/logged2.php');


                    }



mysql_close();

 ?>

您是对的，但在本例中，您的数组是
行
，它应该在

$_SESSION['points'] = $rows['points']

它应该在
while
循环中：

    WHILE($rows = mysql_fetch_array($query)){
     $exsists = 1;
     $_SESSION['points'] = $rows['points']
     break;
     }

但是，这样做可能更好：

if(mysql_num_rows($result) == 1) {
  //Login Successful
  rows = mysql_fetch_assoc($result);
  $_SESSION['points'] = $rows['points']
  $_SESSION['usern']=$uname;
  $_SESSION['logged']=1;

  header('Location: http://wwsdipts/logged2.php');
}


<?php

// start session (required on every page that uses sessions
session_start();

// db auth
$username="asdin";
$password="1sdA2";
$database="a75sdting";

// user auth
$pword = $_POST['pword']; // should use either $_POST or $_GET, NOT $_REQUEST
$uname = $_POST['uname']; // should use either $_POST or $_GET, NOT $_REQUEST

// open db connection
$conn = mysql_connect('mysqsdst.com',$username,$password);
@mysql_select_db($database,$conn) or die( "Unable to select database");

// check user
$query = mysql_query("SELECT * FROM `username` WHERE `password` = '$pword' AND `username` = '$uname'");

if(mysql_num_rows($query)){
    // user exists
    $row = mysql_fetch_assoc($query);
    $_SESSION['usern']=$uname;
    $_SESSION['logged']=1;
    header('Location: http://wwsdipts/logged2.php');
}else{
    header('Location: http://wwsdipts/login.php'); // take them back to login page if incorrect details
}

// close db connection
mysql_close($conn);

?>
