我正在嘗試使用POST的簡單表單，但無法將輸入傳遞到頁面。文件是「agenda.php」，代碼如下（最終形式部分）：無法使用POST傳遞表單信息
<?php
/* includes lib */
include_once("lib.php");
?>

<h2>Your Agenda</h2>
<?php
if(isset($_SESSION['name']))
{
if(isset($_SESSION['meetingCode']))

$firstDate = getFirstDate($_SESSION['meetingCode']);
if($firstDate != "")
{
echo "<h3>Organizing meeting starting from ".$firstDate."</h3>";
?>
<?php
}
else
{

unset($_SESSION['meetingCode']);
header("Location: agenda.php");
}

這段代碼的行爲是：
- 它總是顯示形式
- $ _ POST ['name']永遠不會設置
對於其他信息代碼不顯示問我，我會更新它。由於
僅供參考，lib.php如下：
<?php
$hostDB = "localhost";
$userDB = "root";
$passDB = "";
$dataDB = "scheduler";
function printAlertScript($msg)
{
echo "<script type=\"text/javascript\">
<!--
alert(\"$msg\");
//-->
</script>";

也addUser.php，在同一目錄下，並用相同的文件包括具有類似的形式工作正常：
<?php
/* includes lib */
include_once("lib.php");
global $meetingPassword;
/* if it is the first time tries to create the meeting */
if(isset($_POST['monthInput']) && isset($_POST['dayInput'])
&& isset($_POST['yearInput']) && isset($_POST['daysRange'])
&& isset($_POST['usernameInput']))
{
$unixTime = mktime(0,0,0, $_POST['monthInput'],
$_POST['dayInput'], $_POST['yearInput']);
if($unixTime === false || $unixTime < time())
{
printAlertScript("Unable to use date");
header("Location: index.php");
}
$meetingCode = createMeeting($unixTime, $_POST['daysRange']);
if(isset($meetingCode) && is_int($meetingCode) && $meetingCode >= 0)
{
addUser($meetingCode, $_POST['usernameInput']);
$_SESSION['name'] = $_POST['usernameInput'];
$_SESSION['meetingCode'] = $meetingCode;
}
else
header("Location: index.php");
unset($_POST['monthInput']);
unset($_POST['dayInput']);
unset($_POST['yearInput']);
unset($_POST['daysRange']);
unset($_POST['usernameInput']);
}
/* if someone has been invited */
if(isset($_POST['friendInput']) && isset($_SESSION['meetingCode']))
{
addUser($_SESSION['meetingCode'], $_POST['friendInput']);
unset($_POST['friendInput']);
}
?>

另外，如果我嘗試引用POST變量我得到

您發佈的文件的名稱是什麼？ – genesis
對不起，我忘了它「agenda.php」 – gc5
