使用PHP在表单提交后将数据传递到另一个页面
我已经读过很多类似的问题,所以我知道这个问题以前已经得到了回答,但现在我的问题是为什么我所做的不起作用 我是web开发的新手,正在开发一个web表单,将提交的数据传递到CSV文件。我现在做的是,在表单页面“form.php”上完成所有表单验证之后,它将用户发送到另一个页面“submittedApplication.php”,在同一个语句中,我的所有代码都将数据推送到CSV中 我需要的是将一个特定变量从“form.php”传递到“submittedApplication.php”。这是一个参考号,我有一个随机生成器,在form.php上 在我的代码中,我使用一个函数来创建参考号,并将其存储在名为$result的变量中。在我使用的验证的底部使用PHP在表单提交后将数据传递到另一个页面,php,html,css,post,Php,Html,Css,Post,我已经读过很多类似的问题,所以我知道这个问题以前已经得到了回答,但现在我的问题是为什么我所做的不起作用 我是web开发的新手,正在开发一个web表单,将提交的数据传递到CSV文件。我现在做的是,在表单页面“form.php”上完成所有表单验证之后,它将用户发送到另一个页面“submittedApplication.php”,在同一个语句中,我的所有代码都将数据推送到CSV中 我需要的是将一个特定变量从“form.php”传递到“submittedApplication.php”。这是一个参考号,
header('Location: submittedApplication.php?result={$result}');
试着把它传过去,然后在第二页我用
echo $_GET['result'];
尝试获取变量
如果你在我的代码中发现了它,我也尝试了隐藏输入法,但也没有用
这是我的form.php主页

我通常处理在页面之间传递值的方法是使用会话变量
您可以在form.php页面中执行此操作
session_start();
$SESSION_u[“result”]=$result;
然后在另一页中执行以下操作
session_start();
if(isset($SESSION_["result"]) {
$result = $SESSION_["result"];
}
只需确保在处理完会话变量后销毁或取消设置它们。为什么这么长?D:@JustCarty你会怎么做呢?这里的代码太多了。找到相关部分并发布。我没有阅读您的所有代码,但此行中的{}不必要标题('Location:submittedApplication.php?result={$result}')代码>。它应该是header('Location:submittedApplication.php?result='.$result')
@Qirel我已经提取了之前存在的大约80%的代码,我只保留了表单的基本外壳,只有几个声明,但保留了随机ID生成器的部分以及提交它的验证(如果正确的话)。
session_start();
if(isset($SESSION_["result"]) {
$result = $SESSION_["result"];
}
