Forum : Ce message ne me quitte pas ... Undefined property: PostsController

Bonjour,

Ce message ne me quitte pas depuis le début des tutos ...

J'ai revérifier les codes et je ne parviens pas à trouver la source du problème.

Au tuto numéro 6 il à fallu faire une nouvelle page "admin_index", au début la page s'affichait correctement mais dès que j'ai ajouté le :

<a href="<?php echo Router::url('admin/posts/edit/'.$v->id); ?>">Editer</a>

L'erreur est revenue ...

Voici le code ma page "admin_index.php":

<div class="page-header">
    <h1><?php echo $total; ?> Articles</h1>
</div>
<table>
    <thead>
        <tr>
            <th>ID</th>
            <th>En ligne ?</th>
            <th>Titre</th>
            <th>Action</th>
        </tr>
    </thead>
    <tbody>
        <?php foreach($posts as $k=>$v): ?>
            <tr>
                <td><?php echo $v->id; ?></td>
                <td><span class="label <?php echo($v->online==1)?'success':'error'; ?>"><?php echo ($v->online==1)?'En ligne':'Hors ligne'; ?></span></td>
                <td><?php echo $v->name; ?></td>
                <td>
                    <a href="<?php echo Router::url('admin/posts/edit/'.$v->id); ?>">Editer</a>
                    <a onclick="return confirm('Voulez vous vraiment supprimer ce contenu'); " href="<?php echo Router::url('admin/posts/delete/'.$v->id); ?>">Supprimer</a>
                </td>
            </tr>
        <?php endforeach; ?>
    </tbody>
</table>
<a href="<?php echo Router::url('admin/posts/edit'); ?>" class="primary btn">Ajouter un article</a>

et celui de ma page "PostsController.php" :

<?php

Et ci-dessous une partie du code de la page "Model.php" la ou l'erreur parle findFirst() :

public function find($req = array()){        
        $sql = 'SELECT ';

        if(isset($req'fields'])){
            if(is_array($req'fields'])){
                $sql .= implode(', ', $req'fields']);
            }else{
                $sql .= $req'fields'];
            }
        }else{
            $sql .= '*';
        }

        $sql .= ' FROM '.$this->table. ' as '.get_class($this).' ';

        // Construction de la condition
        if(isset($req'conditions'])){
            $sql .= 'WHERE ';
            if(!is_array($req'conditions'])){
                $sql .= $req'conditions'];
            }else{
               $cond = array();
               foreach($req'conditions'] as $k=>$v){
                   if(!is_numeric($v)){
                      $v = '"'.mysql_real_escape_string($v).'"';
                   }
                   $cond] = "$k=$v";
               }
               $sql .= implode(' AND ', $cond);
            }
        }

        if(isset($req'limit'])){
            $sql .= 'LIMIT '.$req'limit'];            
        }       

        $pre = $this->db->prepare($sql);
        $pre->execute();
        return $pre->fetchAll(PDO::FETCH_OBJ);        
    }

    public function findFirst($req){
        return current($this->find($req));
    }

Si vous avez un début de solution à me soumettre ...

Bonne journée à tous.
