Question

我有一个文件，用于传递$ _SESSION数据库的内容

$uid = mysqli_real_escape_string($conn, $_POST['uid']);
$pwd = mysqli_real_escape_string($conn, $_POST['pwd']);
$sql = "SELECT * FROM users WHERE user_uid = '$uid' OR user_email = '$uid'";
$result = mysqli_query($conn, $sql);
$row = mysqli_fetch_assoc($result)
$_SESSION['u_id'] = row['user_id'];
$_SESSION['u_first'] = row['user_first'];
$_SESSION['u_last'] = row['user_last'];
$_SESSION['u_email'] = row['user_email'];
$_SESSION['u_uid'] = row['user_uid'];
header("Location: ../index.php?login=sucess");

在我的头文件中，我使用附加到index.php的session_start（）开始会话。

<?php
include_once 'header.php';
?>

<section class="main-container">
    <div class="main-wrapper">
        <h2>Home</h2>
        <?php
            if (isset($_SESSION['u_id'])) {
                echo "Bem-vindo!";
                print_r($_SESSION);
            }
        ?>
    </div>
</section>

<?php
    include_once 'footer.php';
?>

就是这样： enter image description here

所以看来我的数组都充满了“ r”，我真的不知道为什么，有什么想法吗？

Answer 1

请更新$row而不是row

示例

$_SESSION['u_id'] = row['user_id'];

替换为

$_SESSION['u_id'] = $row['user_id'];

所有变量。

Answer 2

$uid = mysqli_real_escape_string($conn, $_POST['uid']);
$pwd = mysqli_real_escape_string($conn, $_POST['pwd']);
$sql = "SELECT * FROM users WHERE user_uid = '$uid' OR user_email = '$uid'";
$result = mysqli_query($conn, $sql);
$row = mysqli_fetch_assoc($result)

session_start(); // You need to this function

$_SESSION['u_id'] = $row['user_id'];
$_SESSION['u_first'] = $row['user_first'];
$_SESSION['u_last'] = $row['user_last'];
$_SESSION['u_email'] = $row['user_email'];
$_SESSION['u_uid'] = $row['user_uid'];
header("Location: ../index.php?login=sucess");

Answer 3

由于您错过了$变量row。它应该像$row['user_id']

$_SESSION['u_id'] = $row['user_id'];
$_SESSION['u_first'] = $row['user_first'];
$_SESSION['u_last'] = $row['user_last'];
$_SESSION['u_email'] = $row['user_email'];
$_SESSION['u_uid'] = $row['user_uid'];

$ _SESSION个变量返回r
