我的目的是存儲會話值并將其傳遞給我的page2_form.php。在將會話添加到我的代碼之前，我能夠將用戶定向到頁面，無論他/她從選擇->選項中選擇什么。我的 form 操作是 loadpage.php，每個選項都有一個 switch case，因為每個選項都是不同的形式（我現在只有一個，但稍后會添加更多）。添加會話變量后，我添加了 header('Location: loadpage.php'); 但它對我不起作用。它保存會話值但不引導我的頁面。我嘗試將表單操作更改回 header('Location: loadpage.php'); 但隨后我無法存儲會話值。我是 php/html 的新手，仍在學習，但找不到解決方案。如果需要，我可以發布更多代碼。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">

您有一些需要解決的問題，但我認為主要問題是，當您重定向時，您的帖子不再設置，因此您只想直接發布到目標頁面：
<form role="form" action="loadpage.php" method="POST" name="theForm" id="theForm">
然后在該頁面上執行會話操作。另外，我會創建一個函數來獲取您的請求，以便您可以進行一些過濾：
<?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 Se?mediniz.");
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;
如果您確實想先發布到同一頁面然后重定向，則在您的 loadpage.php 上您需要使用會話值而不是 $_POST 進行重定向值：
<?php
switch($_SESSION['selectedPage']) {
case "page_0":
# Since everything else redirects, just die here
die("Konu Se?mediniz.");
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.
