from my last post I figured out how to logout users when they delete the accounts they're logged into and checking the sessions they're using, but it isn't automatic and needs a page refresh which means the user has time to delete other users on the admin page. I want to make it so the moment the account is deleted they're logged out without refresh... is that possible? this is the current code: <?php function pdo_connect_mysql() { $DATABASE_HOST = 'localhost'; $DATABASE_USER = 'root'; $DATABASE_PASS = ''; $DATABASE_NAME = 'phpticket'; try { return new PDO('mysql:host=' . $DATABASE_HOST . ';dbname=' . $DATABASE_NAME . ';charset=utf8', $DATABASE_USER, $DATABASE_PASS); } catch (PDOException $exception) { exit('Failed to connect to database!'); } } function getUser($email) { global $conn; if (empty($email)) { return null; } $stmt = $conn->prepare("SELECT id, username, email, role FROM users WHERE email = ?"); $stmt->bind_param("s", $email); $stmt->execute(); $result = $stmt->get_result(); if ($result->num_rows > 0) { $userData = $result->fetch_assoc(); $stmt->close(); $user = new stdClass(); $user->id = $userData['id']; $user->username = $userData['username']; $user->email = $userData['email']; $user->role = $userData['role']; $user->isActive = true; return $user; } $stmt->close(); return null; } ?> <!DOCTYPE html> <html> <head> <meta charset="utf-8"> <title>ALnasser | Ticketing System</title> <link href="style.css" rel="stylesheet" type="text/css"> <link rel="stylesheet" href="https://use.fontawesome.com/releases/v5.7.1/css/all.css"> </head> <body> <nav class="navtop"> <div> <img src="alnasser_nobg.png"><h1><a href="index.php" style="color:white;font-size:25px;font-weight: normal;">AlNasser Help Desk</a></h1> <a href="index.php"><i class="fas fa-ticket-alt"></i>Tickets</a> </div> </nav> </body> </html> <?php include 'functions.php'; include "config.php"; $currentUser = getUser($_SESSION['email']); if (!$currentUser || !$currentUser->isActive) { session_destroy(); setcookie('remember_token', '', time() - 3600, "/"); setcookie('email', '', time() - 3600, "/"); session_start(); $_SESSION['login_error'] = 'Session has expired.

for anybody wondering I fixed it I changed setcookie('email', $email, time() + (60 * 60 * 24 * 30), "/", "", true, true); to setcookie('email', $email, time() + (60 * 60 * 24 * 30), "/", "", false, true);

my code was working jus fine yesterday but when I woke up today and tried it out it wouldn't create cookies, and I'm wondering why? <?php session_start(); require_once 'config.php'; if (!isset($_SESSION['email']) && isset($_COOKIE['email'], $_COOKIE['remember_token'])) { $email = $_COOKIE['email']; $token = $_COOKIE['remember_token']; $stmt = $conn->prepare("SELECT u.*, rt.token FROM users u INNER JOIN remember_tokens rt ON u.id = rt.user_id WHERE u.email = ?

AND rt.expires_at > NOW()"); $stmt->bind_param("ss", $email, $token); $stmt->execute(); $result = $stmt->get_result(); if ($result->num_rows > 0) { $user = $result->fetch_assoc(); // Set session variables $_SESSION['username'] = $user['username']; $_SESSION['email'] = $user['email']; $_SESSION['role'] = $user['role']; $_SESSION['location'] = $user['location']; $_SESSION['used_remember_me'] = true; $newToken = bin2hex(random_bytes(32)); $expiresAt = date('Y-m-d H:i:s', time() + (60 * 60 * 24 * 30)); $updateStmt = $conn->prepare("UPDATE remember_tokens SET token = ?, expires_at = ?

I want to make it so when the email and password and remember_me cookies expire the user is logged out but only if they originally clicked remember me, if they didn't nothing will happen. how do I go about doing that? when I enter index and the cookies expired if I clicked remember me before it then it redirects to login page. if you didn't click remember me, you don't redirect anywhere and no cookies are there. also want to make the cookie password into a hashed password or token. how can I do this? how do I alter my already written code to do this? <?php session_start(); require_once 'config.php'; if (!isset($_SESSION['email']) && isset($_COOKIE['email'], $_COOKIE['password'], $_COOKIE['remember_me'])) { $email = $_COOKIE['email']; $password = $_COOKIE['password']; $stmt = $conn->prepare("SELECT * FROM users WHERE email = ?"); $stmt->bind_param("s", $email); $stmt->execute(); $result = $stmt->get_result(); if ($result->num_rows > 0) { $user = $result->fetch_assoc(); if (password_verify($password, $user['password'])) { $_SESSION['username'] = $user['username']; $_SESSION['email'] = $user['email']; $_SESSION['role'] = $user['role']; $_SESSION['location'] = $user['location']; if ($user['role'] === 'admin') { header("Location: admin.php"); } else { header("Location: index.php"); } exit(); } } setcookie('remember_me', '', time() - 3600, "/"); setcookie('email', '', time() - 3600, "/"); setcookie('password', '', time() - 3600, "/"); $stmt->close(); } $errors = [ 'login' => $_SESSION['login_error'] ??

I've made a PHP web crawler and then made a MySQL table called "dex" as in index, then I connected to the database through PDO and tweaked the code to "INSERT" websites that aren't already crawled into the table, "UPDATE" for websites that are crawled, and used URL hashes as an indicator or "id" for links. The terminal shows all the links and links related to them, the if statement works perfectly and there are no major errors, so why does it not insert the data into the "dex" table? every-time I check the table after the process I only find the row that I inserted manually to test the if statement for "UPDATE" or "INSERT". what can I do to fix this issue and insert the date the crawler retrieves?
