upload

[Werwolfe]

Ragazzi ho fatto un upload con mkdir, ma non riesco a capire perchè non funziona

elseif(isset($_GET['action']) && $_GET['action'] == "upload") {
                                       $nome_documento = $_POST['nome_documento'];
                                        $id_condominio = $_POST['id_condominio'];
                                         $id_categoria = $_POST['id_categoria'];
                                        $id_amministratore= $_SESSION['ammid'];
                                        $kira='F';
                                        $a_sql = "SELECT * FROM documenti WHERE id_amministratore = '" . $_SESSION['ammid'] . "' AND link_documento = '" . $_FILES['UploadedFile']['name'] . "'";
                                        $a_query = @mysql_query($a_sql); 
                                        $a_result = @mysql_fetch_array($a_query);
                                    
                                        if($_FILES['UploadedFile']['name'] == $a_result['link_documento']){
