Si,

Code PHP :

<?php 

    if(isset($_POST['pseudo']))

    {

        $pseudo = strtolower(protect($_POST['pseudo']));

        $mdp = strtolower(protect($_POST['mdp']));

        $exist = doquery("SELECT id,pseudo,mdp FROM user WHERE pseudo='{$pseudo}'",1);

         if(!$exist['pseudo']) { $erreur++; }

         if(empty($pseudo)) { $erreur++; }

         if(empty($mdp)) { $erreur++; }

         if($mdp != $exist['mdp']) { $erreur++; }

         $id = $exist['id'];

            if($erreur == 0)

            {

            

                $rep = doquery("SELECT id,nom FROM planete WHERE id_user = '$id'");

                $a = 1;

                while($req = mysql_fetch_assoc($rep))

                {

                    $_SESSION['planete_id'.$a] = $req['id'];

                    $_SESSION['planete_nom'.$a] = $req['nom'];

                $a++;

                }

                $_SESSION['nbr_planete'] = $a;

                $planete_id = $_SESSION['planete_id1'];

    

                $sql = doquery("SELECT  * FROM planete WHERE id_user ='$id' AND id='$planete_id'",1);

                $_SESSION['id_planete'] = $sql['id'];

                $_SESSION['id'] = $exist['id'];
