我正在尝试将 POST 数据发送到 SESSION 变量中
$_SESSION["计划"] = $_POST["计划"]
信息.php显示会话已加载。浏览器 -> 检查元素似乎显示已初始化的会话，但没有键 => 值。
但是我无法显示会话值。Apache 日志中没有错误。
主动态框架：
猫指数.php
<?php
session_start();
?>
<!DOCTYPE html>
<html>
<head>
<meta name="robots" content="index,follow"/>
<link rel="icon" href="images/favicon.ico" type="image/x-icon">
<link rel="shortcut icon" href="images/favicon.ico" type="image/x-icon">
<link rel="stylesheet" type="text/css" href="style.css">
</head>
<body>
<nav class="nav">
<ul>
BLAH
</ul>
</nav>
<div id="content">
<?php
$pages_dir = 'pages';
if (!empty($_GET['p'])) {
$pages = scandir($pages_dir, 0);
unset($pages[0], $pages[1]);
$p=$_GET['p'];
if(in_array($p.'.inc.php', $pages)){
include($pages_dir.'/'.$p.'.inc.php');
}else {
echo 'Sorry, page not found.';
}
}else{
include($pages_dir.'/home.inc.php');
}
?>
</div>
</body>
</html>
用户表单页面：
cat pages/payment.inc.php
<?php
//$_SESSION['plan'] = $_POST['plan'];
?>
<div id="content_pay">
<form action="pages/scheckout.php" method="post">
<div>
<input type="radio" id="plan1" name="plan" value="2500"> Beta membership <br><br>
<input type="radio" id="plan2" name="plan" value="3500"> VIP membership <br><br>
<label for="plan"> If you would like to pay another amount, enter the amount here:</label>
<input type="text" id="plan3" name="plan" />
<br>
<label for="invoice_num"> Enter the invoice number here:</label>
<input type="text" name="invoice_num" /> <br>
<input type="submit" value="submit" name="submit">
</div>
</form>
</div>
基本上，此页面只是为了捕获POST并将其分配给SESSION，然后在加载SESSION的情况下重定向：
猫页/结帐.php
<?php
session_start();
$_SESSION['plan'] = $_POST['plan'];
//needed to prevent weird race conditions
session_write_close();
header("location: ../index.php?p=scheckout");
die();
echo "<br>";
echo $_SESSION['plan'];
?>
去哪里：
cat pages/scheckout.inc.php
<?php
require_once('pages/sconfig.php');
?>
<div id="content_pay">
<form action="pages/scharge.php" method="post">
<div>
<script src="https://checkout.stripe.com/checkout.js" class="stripe-button"
data-key="<?php echo $stripe['publishable_key']; ?>"
myElem.setAttribute('data-amount', <?php $_SESSION['plan']; ?>);
myElem.setAttribute('data-description', <?php $_SESSION['plan']; ?>); >
</script>
</div>
</form>
<br>
<br>
<br>
<br>
<br>
<br>
<br>
<br>
<br>
<br>
<br>
<?php
echo $_SESSION['plan'];
?>
如何让会话从开机自检加载到显示？
在 html 输出之前，您只需启动一次会话。会话将保持打开状态，直到您使用session_destroy或unset $_SESSION变量，或者关闭浏览器。我建议您删除除索引.php之外的所有session_start。
您使用 SESSION['plan']
，但应该使用 echo SESSION['plan']
<script src="https://checkout.stripe.com/checkout.js" class="stripe-button"
data-key="<?php echo $stripe['publishable_key']; ?>"
myElem.setAttribute('data-amount', <?php echo($_SESSION['plan']); ?>);
myElem.setAttribute('data-description', <?php echo($_SESSION['plan']); ?>); >
</script>
