  1. Hi! Thanks a lot for your help. I am going to change what you suggested me. I will let you know if it works. Once again thank you so much for helping.
  2. Hi there. I am actulally working on a login verification process in php. this like my first try i.e i am new on the php code. Ithink i did everything good, but each time i try to run my code by entering real data on the table of my data base, I got a undifined Privilege variable. I sent the code in here so you can give me some help please. the comments on the code are in french, sorry, too much lazy to change them. but I hope you get the logic of the code without the comments. <?php Session_start(); // Start a session on verify page after the verification process ?> <?php // define variables and set empty values $nameErr= $emailErr = $passwordErr = "" ; $name = $email = $password =""; $privilege = ""; $safename=""; #definition de la function function test_input($data) { $data = trim($data); $data = stripcslashes($data); $data = strip_tags($data); return $data; } #PROCESSUS DE VERIFICATION if ($_SERVER["REQUEST_METHOD"]=="POST")# this means if the form has been submited. { $safename= strip_tags($_POST["Username"]);// On rend inoffensives les balises HTML que le visiteur a pu rentrer if (filter_var($safename, FILTER_VALIDATE_EMAIL)) {$safename = $email ;} else {$safename = $name ; }# on ferme apres pour eviter confusion if (empty($_POST["Username"])) { $nameErr="Name is required";} else { $name = test_input($_POST["Username"]); // on évite les carateres non alfanumériques et les espaces blancs if (!preg_match("/^[a-zA-Z0-9]*$/", $name)) { $nameErr="only letters and white space allowed"; }} if (empty($_POST["Password"])) { $passwordErr="Password is required";} else { $password = test_input($_POST["Password"]);} if ($name != null and preg_match("/^[a-zA-Z0-9]*$/", $name) and $password != null or $email !=null and filter_var($email,FILTER_VALIDATE_EMAIL) and $password != null ) { #ici on va crypter le mot de passe # $password= Encrypter::encrypt($password); $username="root"; $password_bdd=""; // On se connecte à MySQL try { $bdd = new PDO('mysql:host=localhost;dbname=espacio_estudiantil;charset=utf8', $username, $password_bdd, array(PDO::ATTR_ERRMODE => PDO::ERRMODE_EXCEPTION)); } catch (Exception $e) // En cas d'erreur, on affiche un message et on arrête tout { die('Erreur : ' . $e->getMessage()); } $req = $bdd->prepare('SELECT * FROM users_list WHERE Email = :Email and Username = :Username and Password = :Password'); $req->execute(array( 'Email' => $email, 'Password' => $password, 'Username' => $name)); /* On affiche chaque entrée provenant de la variable $req une a une dans la nouvelle variable $données sous forme d'array pour la rendre plus lisible*/ while ($donnees = $req ->fetch()) {/*there we create a $Privilege variable with the array $donnees["Privilege"] from the table.[color=#878a85]*/[/size][/color] $Privilege= $donnees["Privilege"]; $Username= $donnees["Username"]; } $req->closeCursor(); // Termine le traitement de la requête //we verify if the person is admin if ($Privilege=="ADMIN") { // we create a session for the administrator $_SESSION["Usertype"] = "ADMIN"; $_SESSION["Username"] = $Username; // on rediriger le visiteur vers la page administrateur header('Location:adminpage.php'); } elseif($Privilege=="USER") // if the person is a user { // we create a session for the User $_SESSION["Usertype"] = "USER"; $_SESSION["Username"] = $Username ; // on rediriger le visiteur vers la page homepage header('Location:homepage.php'); } } } ?> <!DOCTYPE html> <html > <head> <meta charset="UTF-8"> <title>Esquina Estudiantil Form</title> <link rel="stylesheet" href="css-files/login-Style.css"> </head> <body> <!--<div class="esquina-estudiantil"> <div class="box_text"> <h1><span class="text"> Esquina Estudiantil</span></h1> </div> </div>--> <div class="login-page"> <div class="form"> <form class="login-form" method="POST" action="<?php echo htmlspecialchars($_SERVER["PHP_SELF"]);?>"> <label for="Username"></label> <input type="text" id="Username" name="Username" placeholder="Usuario" class="login-input" autocomplete="on"/> <span class="error"><?php echo $nameErr;?></span> <label for="Password"></label> <input type="password" placeholder="Contraseña" id="Password" name="Password" class="login-input" autofocus="ON" /> <span class="error"><?php echo $passwordErr;?></span> <button type="submit" name="Privilege" value="USER" class="login-btn">ENTRAR</button> <p class="message">Que Esperas! <a href="register.php"><em>Hazte miembro</em></a></p> </form> </div> </div> <!--<script src='[url=http://cdnjs.cloudflare.com/ajax/libs/jquery/2.1.3/jquery.min.js]http://cdnjs.cloudflare.com/ajax/libs/jquery/2.1.3/jquery.min.js[/url]'></script>--> <script src="js/index.js"></script> </body> </html>
  3. if you can give me any idea, i would be really grateful. the fact is that i made somee researches, and based on waht i found, it was like there nothing i could do to fix it. the only other solution i saw, was to send all the data to another page <action="verify.php"> and then retrieve the data with $_POST[] and make the connection to the database, after storing the data in tables, redirect user to homage with (header) but my problem was, what if the user didnt enter all the data from the form. i would like to send an error message to notify him there is a data missing but i am not good enough to do this, so i had to find a solution. but if you have any idea, please tell me.
  4. i found another solution. what i wanted to do is to redirect automaticly my user to the homepage after registering his data input in the data base after registering on my webpage. so i created a variable $redirect = ''thanks for registering, please click here to get access to all our services" and then i put a link <a href="homapage.php">Homepage</a>. thus he can keep going by himself on the next pages.
  5. hello there! i am new to php ! i was trying to create a login form. in line 202 <form class="login-form" method="POST" action="<?php echo htmlspecialchars($_SERVER["PHP_SELF"]);?>"> so i can make the verification process on the same page and send the errors to the users when there are some . if there is no error (i.e all data correct) process data and make connection to database(mysql), put the data(username, password, email) in table, then at least redirect user to the home page with (header('Location: homepage.php'). but i got an error while loading page. I know why the problem. I just want someone to give me an advice on how to solve it. please help me !!!!
