顯示歡迎使用php登錄用戶名登錄用戶

Question

這是我的索引。 PHP

<?php 

// Inialize session 
session_start(); 
// Check, if username session is NOT set then this page will jump to login page 
if (!isset($_SESSION['username'])) { 
header('Location: index.html'); 
} 
echo "Welcome", $_SESSION['username']; 
?> 


<div id="content"> 
<p><?php 
if(isset($_SESSION['username'])){ 
    echo "Welcome", $_SESSION['username'];}?> 
</p> 
</div> 

這是我檢查的login.php這裏後，我提交的詳細信息，他們去這裏

<?php 

session_start(); 
ob_start();- 
$host="localhost"; // Host name 
$username=""; // Mysql username 
$password=""; // Mysql password 
$db_name="test"; // Database name 
$tbl_name="members"; // Table name 

// Connect to server and select databse. 
mysql_connect("$host", "$username", "$password")or die("cannot connect"); 
mysql_select_db("$db_name")or die("cannot select DB"); 

// Define $myusername and $mypassword 
$myusername=$_POST['myusername']; 
$mypassword=$_POST['mypassword']; 

// To protect MySQL injection 
$myusername = stripslashes($myusername); 
$mypassword = stripslashes($mypassword); 
$myusername = mysql_real_escape_string($myusername); 
$mypassword = mysql_real_escape_string($mypassword); 
$sql="SELECT * FROM $tbl_name WHERE username='$myusername' and password='$mypassword'"; 
$result=mysql_query($sql); 

// Mysql_num_row is counting table row 
$count=mysql_num_rows($result); 

// If result matched $myusername and $mypassword, table row must be 1 row 
if($count==1){ 

// Register $myusername, $mypassword and redirect to file "login_success.php" 
$_SESSION['username'] = $username; 
$_SESSION['password'] = $password; 
header("location:index1.php"); 
} 
else { 
echo "Wrong Username or Password"; 
} 
ob_end_flush(); 
?> 

我試圖讓登錄的用戶名的index.php歡迎後出現，但它似乎沒有工作，並花了數小時搜索它。

Answer 1

$_SESSION['username'] = 
$username; 
$_SESSION['password'] = 
$password; 

你應該更改爲：

$_SESSION['username'] = 
$myusername; 
$_SESSION['password'] = 
$mypassword; 

因爲$名爲myUsername和$輸入mypassword指從表單數據發送給腳本的用戶名和密碼。
