所以我有两页我用来测试的多页表单。当我单独测试表单的第一部分时，它工作正常。所有内容都根据它从我的数据库中检索的信息进行显示。在我单击提交按钮到下一页之前，一切看起来都很棒，这确认了所有值。当我尝试点击提交时，它也应该传递用户的输入并将其保存为$ _POST []，它会给我一个服务器错误。我对php很新，所以我不太熟悉我可能需要做的每件事。
这是我的第一部分代码：
<?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();
?>

很抱歉，如果代码太多，请告诉我，以便我可以将其删除，因为上次没有提供正确的信息而受到了很多惩罚。
但作为一个更普遍的问题，就是我正在做的，关于使用php变量来显示我的表单，好吗？ 或者这是个大问题？
答案 0 :(得分：0)
while (isset($_SESSION['campsessions']))
{
foreach ($weeklyPrice as $total)
{
$totalPrice = $totalPrice + $total;
}
}
这将是一个无限循环，因为变量永远不会被取消设置。
使用if，而不是while
答案 1 :(得分：0)
您的代码充满了错误 - 但我会说服务器关闭的原因是
while (isset($_SESSION['campsessions']))
如果isset($_SESSION['campsessions'])等于真，你可能也写了
while(true)
这是一个无限循环。 PHP会超时并给你一个错误。使用if代替。
这只是其中一件坏事。我不确定为什么你要发出5个查询来检索表中一行的6个字段，并且有一个if（空（$ _ POST ['campsessions []']））看起来不正确。
