ログインページにセッション変数を保存してからメンバーページに引き継ごうとしていますが、何らかの理由でメンバーページに移動したときにセッション変数が保存されません。
<?php
error_reporting(E_ALL ^ E_NOTICE);
session_start();
$userid = $_SESSION['userid'];
$username = $_SESSION['username'];
?>
それからhtmlの束。次のphpコードは...
<?php
$form = "<form action='login.php' method='post'>
<table>
<tr>
<td><input type='text' name='user' /></td>
</tr>
<tr>
<td><input type='password' name='password' /></td>
</tr>
<tr>
<td><input type='submit' name='loginbtn' value='Login' /></td>
</tr>
</table>
</form>";
if ($_POST['loginbtn']) {
$user = $_POST['user'];
$password = $_POST['password'];
if ($user) {
if ($password){
require("connect.php");
$password = md5(md5("kjfiufj".$password."GSA54"));
//make sure login info is correct
$query = mysql_query("SELECT * FROM users WHERE username='$user'");
$numrows = mysql_num_rows($query);
if ($numrows == 1) {
$row = mysql_fetch_assoc($query);
$dbid = $row['id'];
$dbuser = $row['username'];
$dbpassword = $row['password'];
$dbactive = $row['active'];
if ($password == $dbpassword) {
if ($dbactive == 1) {
//set session info
$_SESSION['userid'] = $dbid;
$_SESSION['username'] = $username;
echo "logged in as <strong>$dbuser</strong>. <a href='member.php'>Click here</a> to go to the member page.";
}
else
echo "User not active";
}
else
echo "Wrong password.";
}
else
echo "The username you entered was not found";
mysql_close();
}
else
echo "What's the password brah?";
}
else
echo "What's the user name brah?";
}
else
echo $form;
?>
会員ページのコードは
<?php
error_reporting(E_ALL ^ E_NOTICE);
session_start();
$userid = $_SESSION['userid'];
$username = $_SESSION['username'];
?>
<?php
if ($username && $userid) {
echo "Welcome <strong>$username</strong>,<a href='logout.php'>Logout</a>.";
}
else
echo "Please login to acces this page <a href='login.php'>Login here</a>";
?>
