目前我有一个基本登录的网站，我只是想知道如何显示登录的唯一用户的名称，技能和描述。这是我到目前为止所做的。我只能找到有关如何将数据显示到表中的文章。这是更新后的代码：
<?php
include('session.php');
require 'config.php';
$sql = "SELECT * FROM profile";
$result = $conn->query($sql);
//echo "id: " . $row["id"]. " - Name: " . $row["firstname"]. " " . $row["lastname"]. "<br>";
?>

数据库表的图片：
session.php文件：
<?php
include('config.php');
session_start();
$user_check = $_SESSION['login_user'];
$ses_sql = mysqli_query($conn,"select email_adress from customer where email_adress = '$user_check' ");
$row = mysqli_fetch_array($ses_sql,MYSQLI_ASSOC);
$login_session = $row['email_adress'];
if(!isset($_SESSION['login_user'])){
header("location:login.php");
}
?>
的login.php：
<?php
include("config.php");
session_start();
if($_SERVER["REQUEST_METHOD"] == "POST") {
// username and password sent from form
$myusername = mysqli_real_escape_string($conn,$_POST['username']);
$mypassword = mysqli_real_escape_string($conn,$_POST['password']);
$sql = "SELECT customer_id FROM customer WHERE email_adress = '$myusername' and password = '$mypassword'";
$result = mysqli_query($conn,$sql);
$row = mysqli_fetch_array($result,MYSQLI_ASSOC);
$active = $row['customer_id'];
$count = mysqli_num_rows($result);
// If result matched $myusername and $mypassword, table row must be 1 row
if($count == 1) {
$_SESSION['login_user'] = $myusername;
header("location: index2.php");
}else {
$error = "Your Login Name or Password is invalid";
}
}
?>

答案 0 :(得分：2)
您需要个人资料上的一个字段链接到客户表（或反之亦然）。
电子邮件可以在两个表中，然后您可以链接到您的$ login_session
SELECT * FROM profile WHERE email = '$login_session' LIMIT 1
在这种情况下，请注意并且不要让用户更改他们的电子邮件（没有验证他们拥有它），也不要让我们创建一个与另一个帐户具有相同凭据的新帐户。
但作为数据库的一个好习惯，最好在客户上 profile_id
<强> session.php文件
$ses_sql = mysqli_query($conn,"select email_adress, profile_id from customer where email_adress = '$user_check' ");
<强> 的index.php
$sql = "SELECT * FROM profile WHERE profile_id = $profile_id LIMIT 1";
顺便说一句： - 尝试在数据库和表示层之间分离关注点。您应该阅读有关MVC的更多信息。
