Question

如下所示，我有一个登录页面，它将根据结果返回索引。当我来到这个页面它什么也没做。会话等注册和登录，但我必须手动重新进入我自己的页面？

<?php
session_start();

include("connect_db.php");

$tbl_name="users"; 
$email=$_POST['email']; 
$pass=$_POST['pass']; 

$sql="SELECT * FROM $tbl_name WHERE email='$email' and pass='$pass'";
$result=mysql_query($sql);
$count=mysql_num_rows($result);

if($count==1){

while($row = mysql_fetch_array($result))

$username=$row['username']; 

$_SESSION['username']=$username;


header('location: index.php?login=yes');

}else {

header('location: index.php?login=no');

}

?>

Answer 1

尝试如下：

<?php
session_start();

include("connect_db.php");

$tbl_name="users";
$email=$_POST['email'];
$pass=$_POST['pass'];

$sql="SELECT * FROM $tbl_name WHERE email='$email' and pass='$pass'";
$result=mysql_query($sql);
$count=mysql_num_rows($result);

if($count==1)
{
    while($row = mysql_fetch_array($result))
    {
        $username=$row['username'];
        $_SESSION['username']=$username;
    }
    header('location: index.php?login=yes');
}
else {
    header('location: index.php?login=no');
}
?>

登录时标头位置不起作用
