Wie lade ich dieses Bild zusammen mit meinem Benutzernamen hoch?

Question

Ich habe diesen Code ausgearbeitet, um mit einiger Hilfe richtig hochzuladen und jetzt kann ich nicht den Benutzernamen in der Datenbank sehen, wenn ich das Bild hochladen. Muss ich etwas wie session_start() in die Upload-Datei einfügen? Ich denke, ich habe bereits meine Sitzung eingestellt, wann immer ich mich anmelde.

Es könnte etwas mit meiner Frage falsch sein, glaube ich.

<?php 
session_start(); 

if(isset($_SESSION['user_id'])) { 
    header("Location: index.php"); 
} 

include_once 'dbconnect.php'; 

//set validation error flag as false 
$error = false; 

//check if form is submitted 
if (isset($_POST['signup'])) { 
    $first_name = mysqli_real_escape_string($con, $_POST['first_name']); 
    $last_name = mysqli_real_escape_string($con, $_POST['last_name']); 
    $username = mysqli_real_escape_string($con, $_POST['username']); 
    $email = mysqli_real_escape_string($con, $_POST['email']); 
    $password = mysqli_real_escape_string($con, $_POST['password']); 
    $cpassword = mysqli_real_escape_string($con, $_POST['cpassword']); 
    $quote = mysqli_real_escape_string($con, $_POST['quote']); 
    $who = mysqli_real_escape_string($con, $_POST['who']); 

    //name can contain only alpha characters and space 
     $sql = "SELECT * FROM users WHERE username = '".$username."'"; 
     $result = mysqli_query($con,$sql); 
     if(mysqli_num_rows($result)>=1){ 
      $error = true; 
      $username_error ='<div class="error-notice"> 
          <div class="oaerror danger"> 
          <strong>Uh oh!</strong> - That Username is already taken. Please use a different Username. 
          </div>'; 


     }else{ 
     } 
     $sql = "SELECT * FROM users WHERE email = '".$email."'"; 
     $result = mysqli_query($con,$sql); 
     if(mysqli_num_rows($result)>=1){ 
      $error = true; 
      $email_exist ='<div class="error-notice"> 
          <div class="oaerror danger">

          </div>'; 


     }else{ 
     } 

    if (!preg_match("/^[a-zA-Z ]+$/",$first_name)) { 
     $error = true; 
     $firstname_error = '<div class="error-notice">

    } 

    if (!preg_match("/^[a-zA-Z ]+$/",$last_name)) { 
     $error = true; 
     $lastname_error = '<div class="error-notice"> 
          <div class="oaerror danger"> 
          <strong>Uh oh!</strong> - Last Name must contain only alphabets and space. 
          </div>'; 

    } 

    if(!filter_var($email,FILTER_VALIDATE_EMAIL)) { 
     $error = true; 
     $email_error = '<div class="error-notice"> 
          <div class="oaerror danger"> 
          <strong>Uh oh!</strong> - Please Enter Valid E-mail. 
          </div>'; 
    } 
    if(strlen($password) < 6) { 
     $error = true; 
     $password_error = '<div class="error-notice"> 
          <div class="oaerror danger"> 
          <strong>Uh oh!</strong> - Password must be minimum of 6 characters. 
          </div>'; 
    } 
    if($password != $cpassword) { 
     $error = true; 
     $cpassword_error = '<div class="error-notice"> 
          <div class="oaerror danger"> 
          <strong>Uh oh!</strong> - Make sure your passwords match. 
          </div>'; 

    } 
    if (!$error) { 
     if(mysqli_query($con, "INSERT INTO users(first_name,last_name,username,email,password,quote,who) VALUES('" . $first_name . "', '" . $last_name . "', '" . $username . "', '" . $email . "', '" . md5($password) . "', '" . $quote . "', '" . $who . "')")) { 
      $successmsg = '<div class="error-notice"> 
          <div class="oaerror success"> 
          <strong>Wooh!</strong> - Successfully Registered! <a href="login.php">Click here to Login</a>

     } else { 
      $errormsg = '<div class="error-notice"> 
          <div class="oaerror info"> 
          <strong>Hmm.</strong> - Error in registering...Please try again later. 
          </div>'; 


     }

Answer 1

Sie haben $ username nicht in Ihrem Code festgelegt. Ihre Select-Abfrage funktioniert nicht ordnungsgemäß. Zuerst müssen Sie $ username setzen. Sonst können Sie den Benutzernamen aus der Datenbank durch andere Details wie useremail, userID usw. abrufen.
