我正在尝试用消息"表格提交成功回复一个div"一旦用户提交了表单,就在下一页上。
我试图通过使用$ _GET ['成功']来做到这一点,但似乎无法显示消息,有人可以指出我正确的方向。
代码:
submit_form.php:
session_start();
$_SESSION['success'] = "<div class='success'>Form Submitted Successfully</div>;
header("Location: index.php?success=$success");
的index.php:
<?php
$_GET['success'] ?>

session_start();
$_SESSION['success'] = "<div class='success'>Form Submitted Successfully</div>;
header("Location: index.php");
您正在使用短信设置会话,所以您只需要在index.php页面上回显会话变量
<?php
if(isset($_SESSION['success']))
{
echo $_SESSION['success'];
}
?>
同时将session_start();
放在每页的开头。

由于您已经设置了session
变量,只需在index.php文件中设置echo
session_start();
<?php echo $_SESSION['success']; ?>
答案 2 :(得分:0)
您将值存储在变量$_SESSION['success']
中并传递未定义的$success
以便抛出错误
使用以下代码替换您的代码:
session_start();
$success = "<div class='success'>Form Submitted Successfully</div>"; // use the $success
//encode the URL parameter as :
$success = urlencode($success);
header("Location: index.php?success=$success");
在index.php中,只需回显成功:
<?php
echo isset($_GET['success'])?$_GET['success']:'Error!';
?>
希望这会有所帮助!

您的第一页无需使用前两行。只需使用重定向,就像在第三行使用它一样,并在下一页显示消息&#34; index.php&#34;像这样:
第一页:
header("Location: index.php?success=done");
Index.php页面:
if(isset($_REQUEST['success'])=="done")
{
echo "<div class='success'>Form Submitted Successfully</div>";
}

代码中的错误数量巨大:
submit_form.php:
<?php
session_start();
$_SESSION['success'] = "<div class='success'>Form Submitted Successfully</div>"; // added " at the end
header("Location: index.php?success"); //Do NOT pass HTML in here. That makes an XSS security vulnerability
?>
的index.php:
<?php
session_start(); //ALWAYS start with session_start if you use sessions. session_start should be at the very beginning of your page.
if(isset($_GET['success']))
echo $_SESSION['success']; //you put your data in _SESSION, you echo it from _SESSION
?>

它应该100%工作。
第一页:
header("Location: index.php?success=done");
Index.php页面:
if(isset($_REQUEST['success'])=="done")
{
echo "<div class='success'>Form Submitted Successfully</div>";
}
