所以我在php中有这个页面。我想要做的是当用户在第一页中输入数量时，点击预览后，它将在第二页显示数量。
我只是PHP的初学者，希望有人能提供帮助。 谢谢。
第一页（这是用户输入数量的页面）
<?php
include("webconfig.php");
session_start();
$_SESSION['qty'] = $qty;
if(!isset($_SESSION["UID"]) || $_SESSION["ACTIVE"] == '0')
header("location:login.php");
$code = $_REQUEST["code"];
$desc = $_REQUEST["desc"];
$price = $_REQUEST["price"];
?>

答案 0 :(得分：0)
尝试使用此方法使用会话
从一个页面获取值到另一个页面<强> first.php
<?php
if(!empty($_POST)){
session_start();
//get the value form form submission and set it to session
$_SESSION['testvalue']=$_POST['test'];
header('location:second.php');
}
?>
<form action="first.php" method="post">
<input type="text" value="" name="test">
<input type="submit" value="test">
</form>
<强> second.php
<?php
session_start();
//get the value from session
$value=$_SESSION['testvalue'];
echo $value;
?>
