$ _SESSION übergibt keine Werte zwischen den Seiten. Php

Question

Ich habe 3 Dateien. (loginFunctions.php, login.php, index.php) in login.php, nehme ich die Werte und übergeben es an loginFunction.php die Werte zu überprüfen und die userID aus einer vorbereiteten Erklärung wählen sie login.php zurückzukehren. Danach ruft login.php eine Methode namens (get('value')) auf, um die userID zu übergeben und die Benutzerinformationen zurückzugeben. Ich habe die Sitzung in den Login- und Indexseiten gestartet. Ich habe versucht, die Informationen, die in der Sitzung gespeichert wurden, wiederzugeben, aber nichts kehrt zurück. Meine Codes

:

loginFunction.php

<?php 

function absolute_url($page = 'index.php') { 
    //header('Location: http:\\localhost'); 
    //exit(); //terminates the script 

    $url = 'http://' . $_SERVER['HTTP_HOST'] . dirname($_SERVER['PHP_SELF']); 
    $url = rtrim($url, '/\\'); 
    $url .= '/' . $page; 

    return $url; 
} 

function checkLogin($email = '', $password = '') { 
    $errors = array(); 

    if (empty($email)){ 
     $errors[] = 'You must enter your email'; 
    } 
    if (empty($password)){ 
     $errors[] = 'You must enter a password'; 
    } 
    if (empty($errors)) { 
////set up database econnection 
     require_once 'DO_Classes/mysqli_connect.php'; 

     $db = new Database(); 
     $dbc = $db->getConnection(); 

     $stmt = $dbc->prepare("SELECT user_ID FROM User WHERE user_email=? AND AES_DECRYPT(user_password, 'p0ly')=?"); 

     if ($stmt) { 
      $stmt->bind_param('ss', $email, $password); 

      if ($stmt->execute()) { 
       $stmt->store_result(); 
       $stmt->bind_result($user_ID); 
       $stmt->fetch(); 
       $stmt->close(); 
       if(!empty($user_ID)){ 
        return array(true, $user_ID); 
       }else{ 
        /* 
        * <div class=\"alert alert-success alert-dismissable\"> 
           <button type=\"button\" class=\"close\" data-dismiss=\"alert\" aria-hidden=\"true\">&times;</button> 
           Invalid email or password 
          </div> 
        */ 
        $errors[] = '<div class="alert alert-danger alert-dismissable"> 
           <button type="button" class="close" data-dismiss="alert" aria-hidden="true">&times;</button> 
           <p align="center">Invalid email or password</p> 
          </div>'; 
       } 

      } else { 
       $errors[] = 'Passwords do not match'; 
      } 
     }else { 
      echo '<p class="error"> Oh dear. There was a databse error</p>'; 
      echo '<p class = "error">' . mysqli_error($stmt) . '</p>'; 
     } 
    } 
    return array(false, $errors); 
} 

?> 

login.php

<?php 
if (isset($_POST['submitted'])) { 
    //require_once is similar to 'include' but ensures the code is not copied multiple times 
    require_once('Functions/loginFunctions.php'); 

    //list() is a way of assigning multiple values at the same time 
    //checkLogin() function returns an array so list here assigns the values in the array to $check and $data 
    list($check, $data) = checkLogin($_POST['email'], $_POST['password']); 


    if ($check) { 
     //setcookie('FName', $data['FName'], time()+ 900) ; //cookie expires after 15 mins 
     //setcookie('LName', $data['LName'], time() + 900) ; 
     session_start(); 
     require_once 'Classes/DO_Users.php'; 
     $user = new DO_User(); 
     $user->get($data); 
     //use session variables instead of cookies 
     //these variables should now be available to all pages in the application as long as the users session exists 
     $_SESSION['userID'] = $user->userID; 
     $_SESSION['userType'] = $user->userTypeID; 
     $_SESSION['last_activity'] = time(); //your last activity was now, having logged in. 
     $_SESSION['expire_time'] = 60 * 5; //expire time in seconds: three hours (you must change this) 
     //to enable $_SESSION array to be populated we always need to call start_session() - this is done in header.php 
     //print_r is will print out the contents of an array 
     //print_r($_SESSION); 
     // 
     //Redirect to another page 

     $url = absolute_url('index.php'); //function defined in Loginfunctions.php to give absolute path for required page 
     //this version of the header function is used to redirect to another page 
     header("Location: $url"); //since we have entered correct login details we are now being directed to the home page 
     exit(); 
    } else { 
     $errors = $data; 
    } 
} 


if (!empty($errors)) { 
    //foreach is a simplified version of the 'for' loop 
    foreach ($errors as $err) { 
     echo "$err <br />"; 
    } 

    echo '</p>'; 
} 

//display the form 
?> 

In index.php, rief ich require_once 'header.php'; die session_start(); aber nichts zurückkehrt, warum?

Answer 1

Ich fand das Problem, es war wegen der vorbereiteten Aussage. Die vorbereitete Anweisung funktionierte nicht, weil die Deklaration der vorbereiteten Anweisung fehlende Werte enthält.
