私は今、頭を壁にぶつけています。私はこれを何時間もいじっていますが、理解できないようです。
あるページから別のページに移動すると、セッション データが保存されません。私はこれを WAMP で設定しました。
Cookie は保存されており、セッション データは、EVERY スクリプトの開始時にリセットした場合にのみ機能します。ここで何をすべきかよくわかりません。それはおそらくばかげたばかげたことですが、どんな意見でも大歓迎です。
私のログインスクリプト：
<?php
include('../partials/_header.php');
include('includes/connectvars.php');
if(!isset($_SESSION['id'])) { //logged in?
if(isset($_POST['submit'])) { // form submitted?
if(!empty($_POST['email']) && !empty($_POST['password'])) { /* Check to make sure post isn't empty in case of JS override/disable */
$email = mysqli_real_escape_string($dbc, trim($_POST['email']));
$password = sha1(mysqli_real_escape_string($dbc, trim($_POST['password'])));
/* query DB */
$query = "SELECT * FROM users WHERE email = '$email' AND password = '$password'";
$result = mysqli_query($dbc, $query) or die ("There was an error with your mySQL query:" . mysqli_error($dbc));
if(mysqli_num_rows($result)==1) { /* Check that matching row exists in users for login */
$row = mysqli_fetch_array($result);
$_SESSION['id'] = $row['id']; // set the session info
$_SESSION['type'] = $row['type'];
$_SESSION['name'] = $row['f_name'];
setcookie('id', $row['id'], time()+ (60*60*24*30));
setcookie('type', $row['type'], time()+ (60*60*24*30));
setcookie('name', $row['f_name'], time()+ (60*60*24*30));
$home_url = '/'; //redirect not working with $_SERVER variable in WAMP. keep an eye for the future
header('Location: '.$home_url);
mysqli_close($dbc);
} else { /* if no match in database ask to resubmit login info or register */?>
<script type="text/javascript" src="../js/jquery.validate.js"></script>
<script>
$(document).ready(function(){
$("#login_form").validate();
});
</script>
<div class="span-24 colborder">
<form id="login_form" action="<?php $_SERVER['PHP_SELF'] ?>" method="post">
<label class="error">Your email and/or password are incorrect. </label><br />
<label class="error">If you haven't already signed up, feel free to <a href="user_registration.php" > register</a> </label><br />

</form>
</div>
<?php
}/* end conditional to check $rows array for username pw match */
} /* end conditional to check that form isn't blank */
else { /* If form is blank ask to resubmit or register */?>
<script type="text/javascript" src="../js/jquery.validate.js"></script>
<script>
$(document).ready(function(){
$("#login_form").validate();

</script>
<div class="span-24 colborder">

</form>
</div>
<?php
} // end else to resubmit in case of blank form
} /* end check if form has been submitted */ else{ /* prompt for login if page visited but login form not submitted */ ?>
<script type="text/javascript" src="../js/jquery.validate.js"></script>

$(document).ready(function(){

<div class="span-24 colborder">

</form>
</div>
<?php
}
} /* end check if cookie isset */ else { //redirect if cookies & session is already set
$home_url = '/';
header('Location: '.$home_url);
}
?>
<?php include('partials/_footer.php'); ?>
これは私のヘッダーです（Cookieが設定されている場合、設定されたセッション変数が含まれます）
<?php //set session if isset cookie but not session
session_start();
if(!isset($_SESSION['id'])) {
if(isset($_COOKIE['id']) && isset($_COOKIE['name']) && isset($_COOKIE['type'])) {
$_SESSION['id'] = $_COOKIE['id'];
$_SESSION['name'] = $_COOKIE['name'];
$_SESSION['type'] = $_COOKIE['type'];
}
} //end if !isset session verify
?>
セッション ID に応じたメニュー出力の例:
<?php
if(isset($_SESSION['type']) && $_SESSION['type'] == "rnr") { //start special runner menu options
?>
<ul class="main_menu">
<li id="how_it_works" class="main_menu"><a class="main_menu" href="/user/bid_task.php">Bid on a task</a></li>
<li id="our_runners" class="main_menu"><a class="main_menu" href="/our_runners.php">Our Runners</a></li>
<li id="login" class="main_menu"><a class="main_menu" href="/user/my_account.php">My account</a></li>
<li id="register" class="main_menu"><a class="main_menu" href="/user/logout.php">Logout</a></li>
</ul>
<?php } /* end runner menu */ ?>
前もって感謝します。
