mysql_num_rows($result)總是等於0，為什嗎？急急
session_start();
$db=mysql_connect("localhost","root","205513")or die("unable to connect");
mysql_select_db("guanliku",$db)or die(mysql_error($db));
mysql_query("set names gb2312");
$name=(isset($_POST['name']))?trim($_POST['name']):'';
$password=(isset($_POST['passwrod']))?trim($_POST['password']):'';
$redirect=(isset($_REQUEST['redirect']))?$_REQUEST['redirect']:'tobiao.php';
if(isset($_POST['submit'])&&$_POST['submit']=='Login'){
$query='select access_level from cms_users
where '.'name="'.mysql_real_escape_string($name,$db).'"and
'.'password=PASSWORD("'.mysql_real_escape_string($password,$db).'")';
$result=mysql_query($query,$db)or die(mysql_error($db));
if(mysql_num_rows($result)>0){
$_SESSION['name']=$name;
$_SESSION['logged']=1;
header('Refresh: 5; URL='.$redirect);
echo '
'.$name.'你將進入你自己的首頁！
';
echo '
click here
';
}
else{
$error='
不合法的使用者名稱'.
'密碼! 請 點擊'.'註冊 如果你還沒有註冊
';
}
mysql_free_result($result);
}
?>
login
if(isset($error)){
echo $error;
}
?>
------解決方案--------------------
echo $query;
將$query的結果放到資料查詢工具運行下,看看結果是不是0.
------解決方案--------------------
$password=(isset($_POST['passwrod']))?trim($_POST['password']):'';
$password=(isset($_POST['password']))?trim($_POST['password']):'';
還是字母打錯了。
