我有一个多步形式,让我们说为了方便它是两步。第一步我想选择一个单选按钮,并根据单选按钮选择它将我带到某个页面,但我也希望选择存储在会话中。我有2页: page1.php中
session_start();
if(isset($_POST['post'])) {
if (($_POST['country'] == 'US')) {
header("Location: US_Products.php"); }
elseif (($_POST['country'] == 'CDN')) {
header("Location: CDN_Products.php"); }
else { die("Error"); }
exit;
}
<form action="<?php echo $_SERVER['PHP_SELF']; ?>" method="post">
<label for="USA">USA:</label>
<input type="radio" name="country" value="US">
<label for="CDN">Canada:</label>
<input type="radio" name="country" value="CDN">
<input type="submit" name="post" value="Go To Filter">
</form>
Page2.php(A或B)
session_start();
$_SESSION['country'] = $_POST['country'];
<?php echo $_SESSION['country']; ?>
当我执行此条件重定向时,不会传递Country选项。会话变量和重定向或会话变量以及PHP_SELF还有问题吗?

第1页:
session_start();
if(isset($_POST['post'])) {
$_SESSION['country'] = $_POST['country'];
if (($_POST['country'] == 'US')) {
header("Location: US_Products.php"); }
elseif (($_POST['country'] == 'CDN')) {
header("Location: CDN_Products.php"); }
else { die("Error"); }
exit;
}
<form action="<?php echo $_SERVER['PHP_SELF']; ?>" method="post">
<label for="USA">USA:</label>
<input type="radio" name="country" value="US">
<label for="CDN">Canada:</label>
<input type="radio" name="country" value="CDN">
<input type="submit" name="post" value="Go To Filter">
</form>
第2页:
session_start();
<?php echo $_SESSION['country']; ?>
或者使用include方法,只需使用一页:
session_start();
if(isset($_POST['post'])) {
if (($_POST['country'] == 'US')) {
include("US_Products.php"); }
elseif (($_POST['country'] == 'CDN')) {
include("CDN_Products.php"); }
else { die("Error"); }
exit;
}
<form action="<?php echo $_SERVER['PHP_SELF']; ?>" method="post">
<label for="USA">USA:</label>
<input type="radio" name="country" value="US">
<label for="CDN">Canada:</label>
<input type="radio" name="country" value="CDN">
<input type="submit" name="post" value="Go To Filter">
</form>
你应该可以在US_Products.php和CDN_Products.php上使用echo $_POST['country']

在重定向之前设置会话变量 - 帖子丢失,因为重定向本质上是一个常规的GET请求
if (($_POST['country'] == 'US'))
{
$_SESSION['country'] = $_POST['country'];
header("Location: US_Products.php");
}
elseif (($_POST['country'] == 'CDN'))
{
$_SESSION['country'] = $_POST['country'];
header("Location: CDN_Products.php");
}
else
{
die("Error");
}
