Question

我有一份很长的数据信息表，我将其分为三页我一直想做的是：

在第1页开始会话以将数组$ sda转移到第2页，

在第2页上有一个会话来将数组$ sda和$ sdb数据转移到第3页，

并在第3页上，将所有数组数据插入数据库并结束会话。

但是，在第3页上，第1页的数组$ sda变为null，只传输数组$ sdb。我没有做什么？

这是我的代码：
第1页，用户填写表单，将值放入数组$ sda，用户点击提交

session_start();
 $_SESSION['sda'] = $sda;
 header("location:enrol.php?a=2");

第2页

session_start();
 $sda = $_SESSION['sda'];
 print_r($_SESSION);

用户填写表单，将值放入数组$ sdb，（数组$ sda中的值应该保留并传递到第3页。它不需要在此页面中打印，但我这样做是为了检查我是否可以从上一页访问其内容 - 工作正常并打印

Array ( [sda] => Array ( [0] => First [1] => Mid [2] => Last [3] => Nick [4] => Cit [5] => Place [6] => January [7] => 1 [8] => 2012 [10] => Grade 1 [9] => School [11] => Home [12] => [13] => A@B.C [14] => [15] => [16] => Guard [17] => Rel [18] => 12345678 [19] => [20] => [21] => [22] => [23] => [24] => [25] => [26] => [27] => [28] => [29] => [30] => [31] => [32] => [33] => [34] => [35] => [37] => [39] => [41] => [36] => [38] => [40] => ) [sdb] => Array ( [9] => [10] => [11] => [12] => [13] => [14] => [15] => [16] => [17] => [18] => [19] => [20] => [21] => a [22] => b [23] => c [24] => d [25] => e [26] => f ) )

用户点击提交（我只想在下一页上看$ sda值。我做得对吗？：z）

session_start();
 $_SESSION['sda'] = $sda;
 $_SESSION['sdb'] = $sdb;
 header("location:enrol.php?a=3");

第3页

session_start();
 $sda = $_SESSION['sda'];
 $sdb = $_SESSION['sdb'];
 print_r($_SESSION);

错误在这里！虽然打印了$ sdb值，但SDA值仍然很低;

Array ( [sda] => [sdb] => Array ( [9] => [10] => [11] => [12] => [13] => [14] => [15] => [16] => [17] => [18] => [19] => [20] => [21] => a [22] => b [23] => c [24] => d [25] => e [26] => f ) )

提交
保存到数据库并销毁会话

Answer 1

从

之后返回的代码中删除此行

 user clicks submit (I just want $sda values on the next page. Am I doing it right? :z)

即

  $_SESSION['sda'] = $sda;

PHP会话数组值在第三页上丢失
