Question

我在两个页面的开头都声明了一个session_start（）函数，但仍然没有将变量传递给会话变量请帮忙这是我已经包含我的login.php

的地方

<?php
include("template/header.php");
include("template/content.php");
include("template/footer.php");
include("login.php");
?>

这是我的login.php文件，其中我已将$ email变量传递给SESSION

<?php
session_start();
include("includes/connection.php");
if(isset($_POST['login'])){
    $email= mysqli_real_escape_string($con,$_POST['email']);
    $pass= mysqli_real_escape_string($con,$_POST['pass']);
    $select_user = "select * from users where user_email= '$email' AND 
    user_pass='$pass' AND status='verified'";

    $query = mysqli_query($con,$select_user);
    $check_user= mysqli_num_rows($query);

    if($check_user===1){
        $_SESSION['usermail']=$email;

        echo "<script>window.open('home.php','_self')</script>";

    } else {

        echo "<script>alert('incorrect details try again')</script>";
    }
}
?>

这是我试图访问会话变量的地方，但它说undefined：usermail但我不明白我在开头给了session_start（）并检查了$ email是否成功从数据库中获取了它的值然后为什么这不起作用

<?php
session_start();
include("includes/connection.php");
?>
