？>



我尝试了什么：



i试过if（mysql_num_rows（$ result）== 1）{

我也试过if（mysql_num_rows（$ result）！= 1）{

解决方案

_POST ['submit']））{

uname =

_POST ['username'];

if(isset($_POST['submit'])){

$uname=$_POST['username'];
$password=$_POST['password'];

$sql="select * from regform where u_user='".$uname."'AND u_password='".$password."' limit 1";

$result=mysql_query($sql);

if(mysql_num_rows($result)){
header("location:loginform/home.php");
echo " You Have Successfully Logged in";
exit();

}
else{
echo " You Have Entered Incorrect Password";
exit();
}

}
?>

What I have tried:

i have tried if(mysql_num_rows($result)==1){
and also i have tried if(mysql_num_rows($result)!=1){

解决方案

_POST['submit'])){

uname=

_POST['username'];
