无法同时存储会话值和重定向页面
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');
}
?>

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 cleanerfunction 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 $arr;}# Don't put this after any "if" statements, just make it first thing on top of# every top-level pagesession_start();# Just stop if invalidif(empty(getRequest('selectedPage'))) die("Invalid request.");# Assign the session variables$_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 runswitch(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: $page = "page1_form"; break;}# Just do one redirect hereheader("Location: {$page}.php");# This may be the end of the script anyway, but best to get in the habit of# exiting after redirectexit;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 $_POST 进行重定向值：<?phpswitch($_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: $pg = "page1_form"; break;}# Just do one redirect hereheader("Location: {$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.
