Question

我试图在会话变量中设置值并尝试访问另一个php文件但我得到未定义的索引错误，但使用的变量是相同的。第一个php文件中的代码是

<html>
<head>
login 
</head>
<body>


<?php


if(isset($_POST['name']))
{
//connecting to data base 

$con=mysqli_connect("localhost:3306","root","","recommender");

// Check connection
if (mysqli_connect_errno())
 {

echo "Failed to connect to MySQL: " . mysqli_connect_error();

}


// username and password sent from form
$myusername=$_POST['name'];
$mypassword=$_POST['password'];

// To protect MySQL injection (more detail about MySQL injection)
$myusername = stripslashes($myusername);
$mypassword = stripslashes($mypassword);
$myusername = mysql_real_escape_string($myusername);
$mypassword = mysql_real_escape_string($mypassword);
echo $myusername."<br>";
 echo $mypassword."<br>";
$sql="SELECT * FROM userlog WHERE name='$myusername' and password='$mypassword'";

$result = mysqli_query($con,$sql) or die(mysqli_error());


// Mysql_num_row is counting table row
$count=mysqli_num_rows($result);

// If result matched $myusername and $mypassword, table row must be 1 row

if($count==1){


session_start();

$_SESSION['user'] = $myusername;

var_dump($_SESSION);

header("location: http://127.0.0.1/proj/dele.html");
}
else {
header("location: http://127.0.0.1/proj/home.html");
}

}
else
{
 echo "not set";
}

?>
</body>
 </html>

第二个php文件是

<html>
<head> 
<title>simply</title>
 </head>
<body>
<?php 
session_start();


print $_SESSION['user'];

var_dump($_SESSION);


?>
</body>
</html>

会话变量不在页面之间共享
