php - 传递包含 php 变量的表单时遇到问题

Question

所以我有两页用于测试的多页表单。当我单独测试表单的第一部分时，它工作正常。一切都根据它从我的数据库中检索到的信息进行显示。一切看起来都很棒，直到我单击提交按钮到下一页，确认所有值。当我尝试点击提交时，它应该也传递用户的输入并将它们保存为 $_POST []，它给了我一个服务器错误。我对 php 很陌生，所以我对我可能需要的一切都不太熟悉。

这是我第一部分的代码：

<?php
    $db = mysql_connect(
  ':/Applications/MAMP/tmp/mysql/mysql.sock',
  'root',
  'root'
);
        if(!$db) die("Error connecting to MySQL database.");
        mysql_select_db('onlineform', $db);

        $newQuery = mysql_query("SELECT newPrice,numberOfWeeks FROM onlineformdata ORDER BY id DESC LIMIT 1");
$newRow = mysql_fetch_row($newQuery);



        $newQuery1 = mysql_query("SELECT newCampSessions FROM onlineformdata ORDER BY id DESC LIMIT 1") or die('Error ' . mysql_error());
$newFoo = mysql_fetch_array($newQuery1);


        $newQuery2 = mysql_query("SELECT pricePerWeek FROM onlineformdata ORDER BY id DESC LIMIT 1") or die('Error ' . mysql_error());
$newFoo1 = mysql_fetch_array($newQuery2);

        $newQuery3 = mysql_query("SELECT numberOfSchools FROM onlineformdata ORDER BY id DESC LIMIT 1");
$newRow1 = mysql_fetch_row($newQuery3);

        $newQuery4 = mysql_query("SELECT schools FROM onlineformdata ORDER BY id DESC LIMIT 1") or die('Error ' . mysql_error());
$newFoo2 = mysql_fetch_array($newQuery4);

$newOldString = $newFoo['newCampSessions'];
$newOldString2 = $newFoo1['pricePerWeek'];
$newOldString3 = $newFoo2['schools'];



$newChangedString = unserialize($newOldString);
$newChangedString2 = unserialize($newOldString2);
$newChangedString3 = unserialize($newOldString3);

$_SESSION['quickVariable'] = $newChangedString2;

settype($newRow[1], "integer");

$limit = $newRow[1];
$anotherLimit = $newRow1[0];
mysql_close();

抱歉，如果代码太多，请告诉我，以便我可以将其剪掉，因为上次没有提供正确的信息，我受到了很多惩罚。

但作为一个更普遍的问题，我在做什么，关于使用 php 变量来显示我的表单，好吗？还是这是大问题？

while (isset($_SESSION['campsessions']))
{   
    foreach ($weeklyPrice as $total)
        {
            $totalPrice = $totalPrice + $total;
        }
}

这将是一个无限循环，因为变量永远不会被取消设置。

使用if，而不是while

您的代码充满了错误 - 但我想说的是让服务器关闭的是

while (isset($_SESSION['campsessions']))

等于isset($_SESSION['campsessions'])true 你不妨写

while(true)

这是一个无限循环。PHP 将超时并给您一个错误。改用 if 。

但这只是正在发生的坏事之一。我不确定您为什么要发出 5 个查询来检索表中一行的 6 个字段，并且有一个 if (empty($_POST['campsessions[]'])) 看起来不正确。
