通过会话PDO查询数据库 [英] PDO Querying database through sessions

问题描述

我正在尝试从数据库中调用数据以显示在用户个人资料上.我在检查用户文件中使用户会话正常工作.但是下面的代码显然是;检索任何内容，因为它不会在我的HTML中的echo语句中回显.有人可以帮忙吗???

I am trying to call data from my database to display on a users profile. I have the user session working correctly in the check user file. However the code below obviously isn; retrieving anything because it won't echo out in the echo statment i have in my HTML. Can someone please help???

require_once 'check.php';

if(isset($_GET['full_name'])){
    $full_name = $_GET['full_name'];
    $username = $_GET['username'];
    $country = $_GET['country'];
    $bio = $_GET['bio'];
    $stmt = $dtb->prepare(" SELECT full_name=:full_name, username=:username, country=:country, bio=:bio FROM users WHERE id=:log_user_id AND username=:log_uname LIMIT 1");
    $arr = array(
        "full_name"     =>  $full_name,
        "username"      =>  $username,
        "bio"           =>  $bio,
        "country"       =>  $country,
        "log_user_id"   =>  $log_user_id,
        "log_uname"     =>  $log_uname
    );
    ArrayBinder($stmt,$arr);
    try{
        $stmt->execute();
        $dtb = null;
        exit();
    }
    catch(PDOException $e){
        echo $e->getMessage();
        $dtb = null;
        exit();
    }
}

推荐答案

因为要从所谓的代码"混乱中分辨出您要做什么是绝对不可能的-因此，只为您提供有关代码的想法需要基于存储在会话中的ID从数据库获取用户详细信息:

As it's absolutely IMPOSSIBLE to tell what are you trying to do from that mess you called "code" - so, just to give you an idea on the code you need to get user details from database based on id stored in a session:

$sql = "SELECT full_name,username,country,bio FROM users WHERE id=?";
$stmt = $dtb->prepare($sql);
$stmt->execute([$_SESSION['log_user_id']]);
$user = $stmt->fetch();

在$ user数组中，您应该使用bio和stuff的名称.检查会话变量名称

here in the $user array you should have name bio and stuff. Check session variable name
