对于所有这些 php 函数，我都为 null：

echo gettype($row);

echo gettype($foo);

echo gettype($foo1);

echo gettype($oldstring);

echo gettype($oldstring2);

echo gettype($changedstring);

echo gettype($changedstring2);

当我没有进行所有查询时，代码就起作用了，我只是将它用作输入值的表单。除了现在，我需要在我的表单中使用 php 来显示某些值。

我还仔细检查了相应列下的数据库，它们确实具有正确和完整的值。查询确实在不同的页面上工作，但在此页面上显示为 null。

这是代码：

<?php
session_start();

    if($_POST['formSubmit'] == "Submit")
    {
    $errorMessage="";

    if (empty($_POST['camperpickedup'])) 
    {
        $errorMessage .="<li>You forgot to select whether the camper is being picked up!</li>";
    }
    if (empty($_POST['personPickingUpCamper'])) 
    {
        $errorMessage ="<li>You forgot to enter the person picking up the camper!</li>";
    }

    $_SESSION['camperpickedup'] = $_POST['camperpickedup'];
    $_SESSION['personPickingUpCamper'] = $_POST['personPickingUpCamper'];

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

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

$query1 = mysql_query("SELECT newCampSessions FROM onlineformdata ORDER BY id DESC    LIMIT 1") or die('Error ' . mysql_error());
$foo = mysql_fetch_array($query1);

$query2 = mysql_query("SELECT pricePerWeek FROM onlineformdata ORDER BY id DESC LIMIT 1") or die('Error ' . mysql_error());
$foo1 = mysql_fetch_array($query2);

$oldstring = $foo['newCampSessions'];
$oldstring2 = $foo1['pricePerWeek'];

$changedstring = unserialize($oldstring);
$changedstring2 = unserialize($oldstring2);

}
?>

您的 MySQL 逻辑包含在失败的布尔检查表单 $_POST['formSubmit'] 中。
