我的目的是存储会话值并将其传递给我的page2_form.php。在将会话添加到我的代码之前，我能够将用户定向到页面，无论他/她从选择->选项中选择什么。我的 form 操作是 loadpage.php，每个选项都有一个 switch case，因为每个选项都是不同的形式（我现在只有一个，但稍后会添加更多）。添加会话变量后，我添加了 header('Location: loadpage.php'); 但它对我不起作用。它保存会话值但不引导我的页面。我尝试将表单操作更改回 header('Location: loadpage.php'); 但随后我无法存储会话值。我是 php/html 的新手，仍在学习，但找不到解决方案。如果需要，我可以发布更多代码。page1_form.php <?php if(isset($_POST['ilerleButon'])){ session_start(); $_SESSION['sayi'] = htmlentities($_POST['sayi']); $_SESSION['madde'] = htmlentities($_POST['madde']); $_SESSION['tarih'] = htmlentities($_POST['tarih']); $_SESSION['selectedPage'] = htmlentities($_POST['selectedPage']); header('Location: loadpage.php'); } ?> <!DOCTYPE html> <html> <head> <!-- Gerekli Meta Tagleri --> <meta charset="utf-8"> <meta name="viewport" content="width=device-width, initial-scale=1, shrink-to-fit=no">

您有一些需要解决的问题，但我认为主要问题是，当您重定向时，您的帖子不再设置，因此您只想直接发布到目标页面：
<form role="form" action="loadpage.php" method="POST" name="theForm" id="theForm">
然后在该页面上执行会话操作。另外，我会创建一个函数来获取您的请求，以便您可以进行一些过滤：
<?php
# You could include this from a separate page, makes your script cleaner
function getRequest($key = false, $type = 'post')
{
switch($type) {
case('get'):
$arr = $_GET;
break;
case('post'):
$arr = $_POST;
break;
default:
$arr = $_REQUEST;
}
if(!empty($key))
return (isset($arr[$key]))? trim($arr[$key]) : null;
return $arr;
}
# Don't put this after any "if" statements, just make it first thing on top of
# every top-level page
session_start();
# Just stop if invalid
if(empty(getRequest('selectedPage')))
die("Invalid request.");
# Assign the session variables
$_SESSION['sayi'] = htmlentities(getRequest('sayi'));
$_SESSION['madde'] = htmlentities(getRequest('madde'));
$_SESSION['tarih'] = htmlentities(getRequest('tarih'));
$_SESSION['selectedPage'] = htmlentities(getRequest('selectedPage'));
# Modify the switch a bit. What you have is not wrong though.
# Make sure to use exit after he redirect so the script doesn't continue to run
switch(getRequest('selectedPage')) {
case "page_0":
# Since everything else redirects, just die here
die("Konu Seçmediniz.");
case "page_1":
$page = "page2_form";
break;
case "page_2":
$page = "page_2";
break;
default:
$page = "page1_form";
break;
}
# Just do one redirect here
header("Location: {$page}.php");
# This may be the end of the script anyway, but best to get in the habit of
# exiting after redirect
exit;
如果您确实想先发布到同一页面然后重定向，则在您的 loadpage.php 上您需要使用会话值而不是 $_POST 进行重定向值：
<?php
switch($_SESSION['selectedPage']) {
case "page_0":
# Since everything else redirects, just die here
die("Konu Seçmediniz.");
case "page_1":
$pg = "page2_form";
break;
case "page_2":
$pg = "page_2";
break;
default:
$pg = "page1_form";
break;
}
# Just do one redirect here
header("Location: {$pg}.php");
exit;
# If this is the end of the script, don't close it with a "?>" it is proper syntax to leave it off
# and then you don't have to worry about any hidden spaces that may mess you
# up down the road.
