Question

我正在尝试发送名为＆＃34; topic＆＃34;的变量的值。从一个php文件到另一个php文件...代码中没有错误，但变量的值没有显示在其他php文件中... 请帮忙......谢谢

<?php

$name = $_POST['name'];

$to = $_POST['to'];

$from = $_POST['from'];

$subject = $_POST['subject'];

$topic = $_POST['topic'];

$message = "From: ".$name."\r\n";

$message .= $_POST['message'];

$headers .= "MIME-Version: 1.0\r\n";

$headers .= "Content-type: text/html\r\n";

$headers = "From:" . $from;


 session_start();

 $_SESSION['top'] = $topic;

 mail($to,$subject,$message,$headers);

?>

另一个php文件是

  <?php 

  session_start();

 $topic = $_GET['top'];

 ?> 

   <h1><center>Meeting Invitation</center></h1>

   <form action="my.php" method="post">

      You are invited for the meeting on <?php echo $topic;?>

       proposed dates are :<br><br>

        Date &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Time<br>

    (isset($dat) && $dat=="val1") echo "checked";?> value = "val1" checked="true" ><br>

Answer 1

您似乎在第二个文件中使用$_GET而不是$_SESSION。

更改

$topic = $_GET['top'];

到

$topic = $_SESSION['top'];

会话没有从一个php值到另一个值获取值
