我目前正在学习如何使用PHP制作登录系统。起初一切似乎都很容易-我将输入数据设置为git config merge.ff false
变量,然后在打开的下一页开始会话。但是,当我刷新页面时,会话仍在工作,但可变数据已删除并且无法识别。
这是我的php,用于设置变量:
$_SESSION
这是我用来检查下一页会发生什么的地方:
<?php
include ("connection.php"); //connects to the database.
if(isset($_POST['login']))
{
$user_name = $_POST['EMAIL'];
$password = $_POST['PASSWORD'];
// echo $user_name, " AND ", $password, "<br>";
$q = "SELECT * FROM ".$table." WHERE EMAIL='".$user_name."' AND PASSWORD= '".$password."' AND IS_ADMIN= 'YES';";
// echo "<br>",$q,"<br>";
$r = mysqli_query($conn, $q);
if(mysqli_num_rows($r) > 0)
{
if(session_id() == '' || !isset($_SESSION))
{
// session isn't started
session_start();
echo "<br>GREAT SUCCESS!!!<br>";
$_SESSION["SESSION_EMAIL"]= $user_name;
$_SESSION["SESSION_PASSWORD"]= $password;
echo $_SESSION["SESSION_EMAIL"], " ", $_SESSION["SESSION_PASSWORD"];
header("Refresh:0; url=\website2.php");
}
}
else echo "<br>FAIL!!!<br>";
}
?>

<?php
session_start();
include ("connection.php"); //connects to the database.
if(isset($_POST['login']))
{
$user_name = $_POST['EMAIL'];
$password = $_POST['PASSWORD'];
// echo $user_name, " AND ", $password, "<br>";
$q = "SELECT * FROM ".$table." WHERE EMAIL='".$user_name."' AND PASSWORD= '".$password."' AND IS_ADMIN= 'YES';";
// echo "<br>",$q,"<br>";
$r = mysqli_query($conn, $q);
if(mysqli_num_rows($r) > 0)
{
if(!isset($_SESSION["SESSION_EMAIL"]))
{
// session isn't started
echo "<br>GREAT SUCCESS!!!<br>";
$_SESSION["SESSION_EMAIL"]= $user_name;
$_SESSION["SESSION_PASSWORD"]= $password;
echo $_SESSION["SESSION_EMAIL"], " ", $_SESSION["SESSION_PASSWORD"];
header("Refresh:0; url=\website2.php");
}
}
else echo "<br>FAIL!!!<br>";
}
?>
然后在第二页上检查类似的内容
<?php
session_start();
if (isset($_SESSION["SESSION_EMAIL"]))
{
echo 'Session is active <br>';
echo $_SESSION["SESSION_EMAIL"];
} else echo"session is ded";
// it prints out an error if it screws up here
?>
希望获得帮助
或
您可以检查其他会话变量

我真的很讨厌这样说,老实说我应该早点做,但是在重新启动XAMPP和PHP服务器之后,一切似乎都已修复,并且该会话现在可以正常工作。现在什么都放不下,页面之间的所有转换都毫不费力。
对于所有对此我这个愚蠢的问题进行思考的人,我深表歉意,同时我还要感谢他们在回答问题上所付出的所有时间和精力。
再次感谢大家!
