    So, I tried your suggestion. The problem was that the form got submitted before entering the data. Anyway, https://codeshack.io/secure-login-system-php-mysql/ I found this site and from here I made a working login. I need to read more about php sessions and post and get. But one last question, for example if I start a session on the config/database.php file must I start another one in the login.php? Or the session must be uniquely defined in one folder? Thank you for all the help. I will mark both answers as solution as they helped me kind of figure out the problem.

    I tried and implemented your suggestion, but the problem remains the same..

    So, I had some undefined variable errors and I solved them by deleting that code from the login_view.php file, as I don't need them now. But if I leave the input fields empty and hit submit, the problem remains the same: nothing happens, no error messages displayed

    cyberRobot, thanks for the advice. I noticed there is a problem with the if(isset($_POST["submit"])), but I don't know how to solve it

    I also tried to add session variables and the result is the same

    <?php if($error["alert"] != ''){ echo "<div class='alert'>".$error["alert"]."</div>"; } ?> I also tried to add session variables and the result is the same

    The error is not displayed. Actually, nothing is displayed. Only a refresh to the page is done. I used the same piece of code for the login page, and there it works wonders.

    Hi! I am trying to use the View Model Design Pattern in my application The problem is that it is the first time I use it and I am a beginner. So, I have the logic in the Model and the "front end" in View. I am talking about a sign up page. In the current Html file I am trying to access an error array from the model file and display it to the user above the input field. Here is the a snippet from the Model (Signup.php) $account = new Account($con); //the account which takes as param the db connection $error = null; //the array // anything the user writes gets inside this array if (isset($_POST["submitButton"])) { $firstName = UnifyFormInput::unifyUserFLName($_POST["firstName"]); $lastName = UnifyFormInput::unifyUserFLName($_POST["lastName"]); $username = UnifyFormInput::unifyFormUserName($_POST["username"]); $email = UnifyFormInput::unifyFormEmail($_POST["email"]); $password = UnifyFormInput::unifyFormPassword($_POST["password"]); //contain true or false based on the query being successful or not $success = $account->register($firstName, $lastName, $username, $email, $password); if ($success) { $_SESSION["userLoggedIn"] = $username; header("Location:index.php"); }else{ $error = $account->getError(Constants::$registerFailed); } } //compact — creates array containing variables and their values //call render function from View file to show the register page content View::render('register', compact('error')); And here is the view: <?php if (!empty($error)) { echo $account->getError(Constants::$loginFailed); } ?> <input type="text" class="form-control" name="firstName" placeholder= "First Name" value="<?php getInputValue("firstName"); ?>" required>
