ho un piccolo problema con include:
Codice PHP:
[*][url="index_1.php?foto=adv"]Advertising[/url][*][url="index_1.php?foto=fashion"]Fashion portraits[/url]
.....
                <?php
                if (!isset($_GET['foto'])) {
                    echo <<<HTML
                        <div id="testo">
                            [img]images/logo.JPG[/img]
                        </div>
HTML;
                }
                if (isset($_GET['foto']) == adv) {
                    include_once 'advertising/adv.php';
                }
                if (isset($_GET['foto']) == fashion) {
                    include_once 'fashion_portraits/fashion.php';
                }
                ?>
quando clicco su uno dei due link mi vengono inclusi entrambi i file.
qualìè il problema??
