PHP：会话状态存储和检索

我似乎无法检索一些值。对于这个PHP程序，我必须存储我的名字，姓氏，电话号码，单选按钮列表的值，以及从选择框/下拉列表中选择电脑游戏。我必须做的是从Ses1文件中存储这些值，并从Ses2文件中检索它们。目前，我可以存储所有5个不同的值。当我点击“提交信息”按钮时，我只能检索名字，姓氏和电话号码值。我能做些什么来从下拉列表中检索单选按钮列表和电脑游戏中的值。我现在的代码在下面。PHP：会话状态存储和检索

<?php 

// we always have to start session state 
session_start(); 

if(isset($_POST["firstNameTextBox"])) 
{ 
    $_SESSION["firstName"] = $_POST["firstNameTextBox"]; 
    header("Location: Session2.php"); 
} 
if(isset($_POST["lastNameTextBox"])) 
{ 
    $_SESSION["lastName"] = $_POST["lastNameTextBox"]; 
    header("Location: Session2.php"); 
} 
if(isset($_POST["telephoneNumberTextBox"])) 
{ 
    $_SESSION["telephoneNumber"] = $_POST["telephoneNumberTextBox"]; 
    header("Location: Session2.php"); 
} 
if (isset($_POST["occupation"])) 
{ 
    $_SESSION["staff"] = $_POST["occupation"]; 
    $_SESSION["sudent"] = $_POST["occupation"]; 
    $_SESSION["faculty"] = $_POST["occupation"]; 
    header("Location: Session2.php"); 

} 
if(isset($_POST["games"])) 
{ 
    $_SESSION["League of Legends"] = $_POST["games"]; 
    $_SESSION["Fallout 4"] = $_POST["games"]; 
    $_SESSION["Overwatch"] = $_POST["games"]; 
    $_SESSION["DOTA 2"] = $_POST["games"]; 
    header("Location: Session2.php"); 
}

你不必存储会话阵列中的每个单选按钮/选择框的选项。

您的SESSION数组索引应该匹配POST数组的索引。

E.g：中$_SESSION["occupation"] = $_POST["occupation"]代替

`$_SESSION["staff"] = $_POST["occupation"]; 
$_SESSION["sudent"] = $_POST["occupation"]; 
$_SESSION["faculty"] = $_POST["occupation"];`

试试这个：

if (isset($_POST["occupation"])) { 
    $_SESSION["occupation"] = $_POST["occupation"]; 
} 

if (isset($_POST["games"])) { 
    $_SESSION["games"] = $_POST["games"]; 
    header("Location: Session2.php"); 
}
